Question 1

The observations show what happened when a student let go of a tennis ball in three different places.

Observation A: On the playground, the ball fell to the ground.
Observation B: In the gym, the ball fell to the floor.
Observation C: At home, the ball fell to the carpet.

Based on these observations, what claim about gravity is best supported?

Gravity only works outside where there is fresh air.
Gravity can be stopped if you hold an object still.
Gravity pulls objects toward Earth in many places. (correct answer)
Gravity pulls harder on tennis balls than on other objects.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically constructing evidence-based claim from multiple observations. Scientific arguments require identifying patterns across observations to form general claims - here, ball falling in three different locations (playground, gym, home) shows gravity acts consistently across different places. For this question, students must recognize the common pattern (ball falls downward) across varied locations and form appropriate claim about gravity's consistency. Choice C is correct because it constructs claim that evidence actually supports - 'gravity pulls objects toward Earth in many places' directly follows from observations of ball falling in multiple locations. This shows the student understands how to generalize from specific observations to broader claim about gravity's universal nature. Choice A represents a common error where students add unsupported restrictions to claim - nothing in observations suggests gravity only works with fresh air. This typically happens because 5th graders may confuse correlation (observations happened in certain places) with causation (those place characteristics are necessary for gravity). To help students: Practice identifying what observations actually show versus what students might assume - ask 'What did we observe? Ball fell in all three places. What can we claim? Gravity works in different places.' Emphasize sticking to what evidence shows without adding extra conditions. Watch for: Students who create overly specific claims that add requirements not supported by evidence, or who focus on irrelevant details (indoor/outdoor, floor type) rather than consistent pattern of falling.

Question 2

A student wrote an argument about gravity.

Claim: "Gravity pulls objects toward Earth."
Evidence: "When we dropped a ball, it fell to the ground."

Which sentence best completes the reasoning that connects the evidence to the claim?

This supports the claim because the ball is round and easy to drop.
This supports the claim because falling to the ground shows the ball was pulled toward Earth. (correct answer)
This supports the claim because the ground is hard and makes a sound.
This supports the claim because balls fall only when they are heavy.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically completing argument by providing appropriate reasoning that connects evidence to claim. Scientific arguments require reasoning that explains how evidence supports claim - here, students must explain why ball falling to ground demonstrates gravity pulling toward Earth. For this question, the claim states gravity pulls toward Earth, evidence shows ball falling to ground, and reasoning must connect these by explaining falling demonstrates pulling toward Earth. Choice B is correct because it provides clear reasoning explaining how evidence logically supports claim - 'falling to the ground shows the ball was pulled toward Earth' directly connects the observed motion (falling) to the claimed force (gravity pulling toward Earth). This shows the student understands reasoning must explain the logical connection between what was observed and what is claimed. Choice A represents a common error where students provide irrelevant characteristics instead of logical connection - being round and easy to drop doesn't explain how falling demonstrates gravity's pull. This typically happens because 5th graders may describe general features rather than focusing on how specific observation (falling) demonstrates specific claim (pulled toward Earth). To help students: Use sentence frames like 'This evidence supports the claim because [explain how observation shows what claim states]' and model thinking aloud: 'The ball fell down. The claim says gravity pulls toward Earth. Falling down means moving toward Earth, so this shows pulling toward Earth.' Watch for: Students who describe object properties or experimental conditions rather than explaining the logical connection between observed behavior and claimed force.

Question 3

The observations show what happened when students used a scale to measure different objects.

Claim: "Gravity pulls on objects even when they are not moving."

Which piece of data best supports the claim?

The apple weighed 2 N on the scale while sitting still. (correct answer)
The apple was red and the book cover was blue.
The scale was made of metal and had numbers on it.
The book was longer than the apple.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically identifying which observations support a claim about gravity acting on stationary objects. Scientific arguments about forces on non-moving objects require evidence of force presence even without motion - scale measurements provide this by showing weight (gravity's pull) on stationary objects. For this question, claim states gravity pulls on non-moving objects, so evidence must demonstrate gravity's effect on stationary items, which scale weight measurements directly show. Choice A is correct because it identifies observation that directly demonstrates the claim - 'apple weighed 2 N on scale while sitting still' shows gravity pulling on stationary apple, as weight is measure of gravity's force. This shows the student understands that scales measure gravitational force and this measurement proves gravity acts even without motion. Choice B represents a common error where students select observation that doesn't relate to claim - describing colors has nothing to do with whether gravity acts on stationary objects. This typically happens because 5th graders may not recognize that weight measurements specifically indicate gravity's pull, or may think any observation about the objects counts as evidence. To help students: Explicitly teach that weight on scale equals gravity's pull, demonstrating with spring scale to show continuous pulling even when object isn't falling. Use examples like 'book on table still pulled by gravity, table pushes back' to show forces present without motion. Watch for: Students who think gravity only acts on falling objects, missing that weight measurements prove gravity's continuous action on all objects whether moving or still.

Question 4

The observations show what happened when a student let go of a tennis ball in three different places.

Observation A: On the playground, the ball fell to the ground.
Observation B: In the gym, the ball fell to the floor.
Observation C: At home, the ball fell to the carpet.

Based on these observations, what claim about gravity is best supported?

Gravity only works outside where there is fresh air.
Gravity can be stopped if you hold an object still.
Gravity pulls objects toward Earth in many places. (correct answer)
Gravity pulls harder on tennis balls than on other objects.

Question 5

The observations show what happened when a student dropped a coin three times from the same height:

Trial 1: The coin fell right away.
Trial 2: The coin fell right away.
Trial 3: The coin fell right away.

Based on this evidence, what claim about gravity is best supported?

Gravity only pulls on metal objects like coins.
Gravity always acts as soon as an object is released. (correct answer)
Gravity sometimes pushes objects upward.
Gravity depends on the color of the object.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically constructing evidence-based claims from patterns in data. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For this question, students must analyze repeated trials showing a coin falling 'right away' each time and determine what claim this pattern supports. Choice B is correct because it constructs a claim that the evidence actually supports - the consistent pattern of the coin falling immediately in all three trials demonstrates that gravity acts as soon as objects are released. This shows the student understands how to draw appropriate conclusions from patterns in data. Choice A represents a common error where students make claims that go beyond what the evidence shows - the data only involves a metal coin, so we cannot conclude gravity only pulls on metal objects. This typically happens because 5th graders may overgeneralize from limited data or confuse the specific example (coin) with a general principle about all objects. To help students: Practice identifying what claims can and cannot be supported by given evidence - 'The data shows a coin falling. Can we claim gravity only works on coins? No, we'd need to test other objects.' Emphasize the difference between 'This happened with a coin' and 'This only happens with coins.' Use multiple examples to build general claims. Watch for: Students who make claims about properties not tested (color, material restrictions), students who ignore the consistent pattern focusing instead on irrelevant details, or students who make claims opposite to the evidence (gravity pushes upward).

Question 6

A student makes this argument:

Claim: "Gravity pulls objects toward Earth."
Evidence: "When I let go of my keys, they fell to the ground."
Reasoning: "Because the keys moved toward the ground without me pushing them down, gravity must be pulling them toward Earth."

Does the evidence support the claim? Why or why not?

Yes, because the keys fell toward the ground when released, which is what the claim predicts. (correct answer)
No, because keys are made of metal and gravity only pulls on metal.
No, because one observation can never be used as evidence in science.
Yes, because the keys are small, and gravity only pulls on small objects.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically evaluating whether evidence actually supports claim and explaining the connection. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For this question, students must evaluate a complete argument about gravity pulling objects toward Earth, with keys falling as evidence. Choice A is correct because it correctly evaluates that evidence does support claim and explains clear connection - keys falling toward ground when released is exactly what we'd expect if gravity pulls objects toward Earth, making this valid supporting evidence. This shows the student understands both how to evaluate evidence-claim relationships and explain the connection. Choice B represents a common error where students add incorrect limitations to gravity - claiming gravity only pulls on metal contradicts scientific understanding that gravity acts on all objects with mass. This typically happens because students may create false rules based on limited examples or everyday misconceptions, not recognizing gravity's universal nature. To help students: Explicitly teach that gravity acts on all objects with mass, not just certain materials. Practice evaluating arguments: 'Does the evidence match what the claim predicts? If claim says gravity pulls toward Earth and we see object move toward Earth, that's a match.' Address misconceptions about gravity being selective. Watch for: Students who add false restrictions (only metal, only small objects), students who reject valid evidence for incorrect reasons (one observation can be evidence), or students who accept evidence without explaining why it supports the claim.

Question 7

The data from a class drop test are shown below. Students dropped each object from the same height and watched what happened.

Claim: "Gravity pulls on all objects."

Which observation from the data best supports the claim?

The paper clip was shiny and the sponge was dull.
All five different objects fell downward when released. (correct answer)
Some objects made a louder sound when they hit the floor.
The objects were dropped in the classroom instead of outside.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically identifying which observations support a specific claim about gravity. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For gravity, common claims include 'gravity pulls all objects toward Earth,' 'gravity always pulls downward,' or 'gravity acts on all objects.' Evidence must be observable (what we see/measure) and directly relevant to the claim. For this question, evaluating which observation best supports 'gravity pulls on all objects' requires finding evidence showing multiple different objects being affected by gravity. Choice B is correct because it identifies observation that directly demonstrates the claim - 'all five different objects fell downward' shows gravity acting on multiple objects, providing pattern-based evidence rather than single instance. This shows the student understands scientific claims must be supported by evidence that directly relates to the claim, and stronger evidence comes from patterns across multiple observations. Choice A represents a common error where students select observation that doesn't relate to claim - describing appearance (shiny/dull) has nothing to do with whether gravity pulls on objects. This typically happens because 5th graders may not yet clearly distinguish between any observation about objects and relevant evidence for specific claim about gravity. To help students: Model identifying relevant evidence by asking 'Does this observation show gravity pulling on objects?' for each choice, emphasizing that evidence must directly demonstrate what claim states. Watch for: Students who think any observation about the objects is evidence for claim about gravity, missing need for observations to show gravity's effect (falling/pulling) not just object properties.

Question 8

Two students gave arguments about gravity.

Student 1:
Claim: "Gravity pulls objects toward Earth."
Evidence: "We dropped 10 different classroom objects, and all of them fell to the floor."
Reasoning: "Because every object moved downward when released, gravity must be pulling them toward Earth."

Student 2:
Claim: "Gravity pulls objects toward Earth."
Evidence: "My favorite ball falls when I drop it."
Reasoning: "Gravity is strong, so it makes the ball fall."

Which argument is better supported by evidence, and why?

Student 2, because one example is enough to prove a claim.
Student 1, because it uses many observations and connects them to the claim. (correct answer)
Student 2, because it uses the word "strong," which is scientific evidence.
Student 1, because dropping objects only works if the objects are the same size.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically evaluating strength of complete arguments and distinguishing between strong and weak evidence. Scientific arguments are stronger when based on multiple observations with clear reasoning versus single examples with vague connections - Student 1 uses pattern across 10 objects while Student 2 uses single instance. For this question, students must compare two complete arguments, evaluating which has stronger evidence (multiple observations vs. single example) and clearer reasoning (logical connection vs. vague statement). Choice B is correct because it identifies the stronger argument based on evidence quality - Student 1's use of 10 different objects provides pattern-based evidence, and reasoning clearly connects observation (all fell) to claim (gravity pulls toward Earth). This shows the student understands that multiple observations create stronger evidence than single instances, and clear logical reasoning strengthens arguments. Choice A represents a common error where students think one example suffices for scientific claims - this misses that patterns across multiple observations provide much stronger evidence than single instances. This typically happens because 5th graders may not yet understand that scientific claims require consistent patterns, not just single supporting examples, and may not recognize importance of sample size. To help students: Compare arguments side-by-side, counting observations and evaluating reasoning clarity. Demonstrate how multiple consistent observations (10 objects falling) provide stronger support than single observation (one ball falling). Practice identifying vague reasoning ('gravity is strong') versus specific connections ('moved downward shows pulled toward Earth'). Watch for: Students who focus on superficial features like favorite objects or word choice rather than evaluating evidence quantity and reasoning quality.

Question 9

The observations show what happened when two students dropped objects at the same time from the same height.

Student 1 dropped a small rubber ball. It fell straight down.
Student 2 dropped a wooden block. It also fell straight down.

What claim about gravity is best supported by these observations?

Gravity only pulls on objects that are round.
Gravity pulls different objects downward toward the ground. (correct answer)
Gravity pushes objects sideways when they are dropped.
Gravity works only when two people drop objects at the same time.

Explanation: This question tests a 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically constructing evidence-based claim. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For gravity, common claims include 'gravity pulls all objects toward Earth,' 'gravity always pulls downward,' or 'gravity acts on all objects.' Evidence must be observable (what we see/measure) and directly relevant to the claim. Reasoning explains the logical connection: 'BECAUSE all dropped objects fall toward ground (evidence), we can conclude that gravity pulls objects toward Earth (claim).' For this question, specific context: evaluating whether observation 'all dropped objects fell toward ground' supports claim 'gravity pulls objects toward Earth' - yes, consistent with claim / identifying which evidence best supports 'gravity pulls on all objects' - would be observation showing different objects (heavy, light, big, small) all fall / explaining how 'water flows downhill' supports 'gravity pulls toward Earth' - water pulled downward by gravity toward Earth. Choice B is correct because it constructs claim that evidence actually supports. This shows the student understands scientific claims must be supported by evidence and reasoning, not just stated / evidence must directly relate to claim / reasoning connects evidence to claim by explaining relationship / stronger evidence is more direct, consistent, and based on multiple observations / complete argument has claim, evidence, and reasoning. Choice A represents a common error where students match evidence to wrong claim / choose weak single observation over strong pattern / provide evidence without reasoning, missing connection to claim / state opinion or belief instead of observation / use circular reasoning (claim supports claim) / ignore that evidence could have alternative explanation. This typically happens because 5th graders may not yet clearly distinguish between claim (statement to be supported), evidence (observations), and reasoning (explanation of connection) / students may restate claim thinking they're providing evidence / students may think any observation about falling is evidence for any claim about gravity, missing need for specific relevance / students may not recognize that stronger evidence comes from patterns across multiple observations, not single instance / everyday language doesn't distinguish 'I think' (opinion) from 'I observed' (evidence) so students may blur these / students may provide evidence but forget to explain how it connects to claim. To help students: Explicitly teach and practice Claim-Evidence-Reasoning structure using graphic organizer with three sections / Model identifying each component: 'What is the claim (statement about gravity)? What is the evidence (what did we observe)? What is the reasoning (how does evidence support claim)?' / Practice with multiple examples: present claims, have students identify what evidence would support them / Compare strong and weak evidence: 'One object fell' vs. 'Every object we dropped fell' - which is stronger evidence for 'gravity pulls all objects'? / Use sentence frames: 'Claim: [statement about gravity]. Evidence: [observation or data]. Reasoning: This evidence supports the claim because [explanation].' / Emphasize that evidence must be observable (what we see/measure, not what we think/believe) and must directly relate to claim. Watch for: Students who restate claim when asked for evidence ('Gravity pulls things down' as evidence for 'gravity pulls things down') / Students who provide reasoning when asked for evidence ('because gravity is a force' is not observation) / Students who provide evidence but can't explain how it supports claim (missing reasoning component) / Students who think any observation about gravity is evidence for any claim about gravity / Students who choose single weak observation over consistent pattern / Students who state opinions ('I think gravity is strong') as if they're evidence / Students who can complete teacher-provided argument structure but can't independently identify claim, evidence, and reasoning in text.

Question 10

The observations show two students discussing gravity:

Student 1 Claim: "Gravity pulls objects toward Earth."
Student 1 Evidence: "When I drop my water bottle, it falls to the ground."

Student 2 Claim: "Gravity pulls objects toward Earth."
Student 2 Evidence: "My water bottle has a cap."

Which student's evidence is better, and why?

Student 1, because the bottle falling is an observation that matches the claim. (correct answer)
Student 2, because the cap proves gravity is pulling the bottle down.
Student 2, because describing the object is the same as giving evidence.
Student 1, because gravity only works when an object is made of plastic.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically distinguishing between strong and weak evidence for claims. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For this question, students must evaluate which student provides better evidence for the claim 'gravity pulls objects toward Earth' - Student 1 observes the bottle falling, while Student 2 describes the bottle having a cap. Choice A is correct because it accurately identifies that Student 1's observation of the bottle falling matches the claim about gravity pulling objects toward Earth, while Student 2's description of the cap is irrelevant to gravity. This shows the student understands evidence must be relevant observations that demonstrate the claim. Choice C represents a common error where students confuse description with evidence - describing an object's features (having a cap) is not the same as providing observational evidence of gravity's effects. This typically happens because students may not yet clearly distinguish between describing objects and providing evidence of forces acting on them, thinking any statement about the object counts as evidence. To help students: Practice sorting statements into 'descriptions of objects' vs. 'observations of what happened.' Emphasize that evidence for gravity must show gravity's effects (falling, pulling) not just object features. Use comparison activities: 'Which tells us about gravity: The ball is red, or The ball fell down?' Watch for: Students who think any statement about an object is evidence, students who don't recognize irrelevant observations, or students who choose based on which student they like rather than evidence quality.

Question 11

A student wrote an incomplete argument.

Claim: "Gravity pulls objects toward Earth."
Evidence: "When we dropped a tennis ball, it fell to the ground."
Reasoning: missing

Which sentence best completes the reasoning?

The tennis ball fell because tennis balls are round and smooth.
This supports the claim because the ball moved downward toward Earth when it was released. (correct answer)
This supports the claim because the ball is used in sports games.
This supports the claim because gravity is the name of a force.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically completing argument by providing missing reasoning that connects evidence to claim. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For this question, students must provide reasoning explaining how a tennis ball falling to the ground supports the claim that gravity pulls objects toward Earth. Choice B is correct because it provides clear reasoning explaining how evidence logically supports claim - explicitly stating that the ball's downward movement toward Earth when released demonstrates gravity's pull, creating the necessary logical connection. This shows the student understands reasoning must explain why the evidence demonstrates the claim. Choice A represents a common error where students provide alternative explanations unrelated to the claim - explaining the fall by the ball's shape rather than gravity misses the point entirely. This typically happens because students may list any explanation for why something happened rather than specifically connecting evidence to the stated claim about gravity. To help students: Use reasoning frames: 'This evidence supports the claim because [specific connection].' Practice identifying whether reasoning actually connects evidence to claim or provides unrelated explanations. Emphasize that reasoning must mention both the evidence and claim, showing their relationship. Watch for: Students who explain evidence using irrelevant properties (round, smooth), students who provide circular reasoning (gravity exists because it's a force), or students who mention unrelated facts instead of connecting evidence to claim.

Question 12

The observations show what happened when a student released a toy car on a ramp.

Observation: The toy car rolled down the ramp toward the floor.

Which reasoning best explains how this observation supports the claim "Gravity pulls downward"?

It supports the claim because the car rolled down toward the lower end, which is closer to Earth. (correct answer)
It supports the claim because the car is made of plastic and plastic likes ramps.
It supports the claim because ramps are smoother than flat floors.
It supports the claim because the car rolled down only because someone pushed it hard.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically explaining reasoning that connects evidence to claim about gravity's downward pull. Scientific arguments require reasoning that explains how observations demonstrate claimed phenomenon - here, car rolling down ramp toward floor must be connected to gravity pulling downward. For this question, students must identify reasoning that logically explains how ramp observation supports claim about downward pull, focusing on direction of motion relative to Earth. Choice A is correct because it provides clear reasoning connecting observation to claim - 'car rolled down toward lower end, which is closer to Earth' explains how downward ramp motion demonstrates gravity's downward (earthward) pull. This shows the student understands that 'downward' means 'toward Earth' and can connect inclined motion to vertical gravitational force. Choice D represents a common error where students attribute motion to other causes, missing gravity's role - claiming car only rolled because pushed ignores that gravity causes downward component of motion on ramps. This typically happens because 5th graders may not recognize that gravity acts on inclined surfaces, causing objects to roll/slide downward even without pushing, or may think horizontal push explains all motion. To help students: Demonstrate releasing objects on ramps without pushing, showing gravity alone causes downward rolling. Use diagrams showing gravity's downward pull creates component of force along ramp. Practice connecting various downward motions (falling, rolling down, sliding down) to gravity's consistent downward pull. Watch for: Students who attribute all motion to pushes/initial forces, missing gravity's continuous role, or who don't recognize that motion along inclines still demonstrates gravity's vertical downward pull.

Question 13

To support the claim that "Gravity is always acting on objects," a student collected these observations:

Observation A: A book resting on a bathroom scale showed a weight reading.
Observation B: A book resting on a desk did not move.
Observation C: A book had a blue cover.
Observation D: A book was made of paper.

Which observation is the best evidence that gravity is always acting, even when an object is not moving?

A book resting on a desk did not move.
A book had a blue cover.
A book resting on a bathroom scale showed a weight reading. (correct answer)
A book was made of paper.

Explanation: This question tests a 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically evaluating whether evidence actually supports claim. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For gravity, common claims include 'gravity pulls all objects toward Earth,' 'gravity always pulls downward,' or 'gravity acts on all objects.' Evidence must be observable (what we see/measure) and directly relevant to the claim. Reasoning explains the logical connection: 'BECAUSE all dropped objects fall toward ground (evidence), we can conclude that gravity pulls objects toward Earth (claim).' For this question, specific context: evaluating whether observation 'all dropped objects fell toward ground' supports claim 'gravity pulls objects toward Earth' - yes, consistent with claim / identifying which evidence best supports 'gravity pulls on all objects' - would be observation showing different objects (heavy, light, big, small) all fall / explaining how 'water flows downhill' supports 'gravity pulls toward Earth' - water pulled downward by gravity toward Earth. Choice C is correct because it correctly evaluates that evidence does support claim and explains clear connection. This shows the student understands scientific claims must be supported by evidence and reasoning, not just stated / evidence must directly relate to claim / reasoning connects evidence to claim by explaining relationship / stronger evidence is more direct, consistent, and based on multiple observations / complete argument has claim, evidence, and reasoning. Choice A represents a common error where students select observation that doesn't relate to claim (claim about direction, evidence about object size) / confuse description with evidence (restate claim instead of providing observation) / confuse evidence (what we observe) with reasoning (why observation supports claim) / match evidence to wrong claim / choose weak single observation over strong pattern / provide evidence without reasoning, missing connection to claim / state opinion or belief instead of observation / use circular reasoning (claim supports claim) / ignore that evidence could have alternative explanation. This typically happens because 5th graders may not yet clearly distinguish between claim (statement to be supported), evidence (observations), and reasoning (explanation of connection) / students may restate claim thinking they're providing evidence / students may think any observation about falling is evidence for any claim about gravity, missing need for specific relevance / students may not recognize that stronger evidence comes from patterns across multiple observations, not single instance / everyday language doesn't distinguish 'I think' (opinion) from 'I observed' (evidence) so students may blur these / students may provide evidence but forget to explain how it connects to claim. To help students: Explicitly teach and practice Claim-Evidence-Reasoning structure using graphic organizer with three sections / Model identifying each component: 'What is the claim (statement about gravity)? What is the evidence (what did we observe)? What is the reasoning (how does evidence support claim)?' / Practice with multiple examples: present claims, have students identify what evidence would support them / Compare strong and weak evidence: 'One object fell' vs. 'Every object we dropped fell' - which is stronger evidence for 'gravity pulls all objects'? / Use sentence frames: 'Claim: [statement about gravity]. Evidence: [observation or data]. Reasoning: This evidence supports the claim because [explanation].' / Emphasize that evidence must be observable (what we see/measure, not what we think/believe) and must directly relate to claim. Watch for: Students who restate claim when asked for evidence ('Gravity pulls things down' as evidence for 'gravity pulls things down') / Students who provide reasoning when asked for evidence ('because gravity is a force' is not observation) / Students who provide evidence but can't explain how it supports claim (missing reasoning component) / Students who think any observation about gravity is evidence for any claim about gravity / Students who choose single weak observation over consistent pattern / Students who state opinions ('I think gravity is strong') as if they're evidence / Students who can complete teacher-provided argument structure but can't independently identify claim, evidence, and reasoning in text.

Question 14

The data from a class drop test are shown below.

Claim: "Gravity pulls on all objects."

Evidence (what the class observed):

A crumpled paper ball dropped from shoulder height fell to the floor.
A small rock dropped from the same height fell to the floor.
A plastic spoon dropped from the same height fell to the floor.
A tennis ball dropped from the same height fell to the floor.

Which observation best supports the claim that gravity pulls on all objects?

The plastic spoon was white and the tennis ball was yellow.
All four different objects fell to the floor when they were dropped. (correct answer)
Gravity is a force that makes things fall, so the objects fell.
The rock fell because it was heavier than the paper ball.

Explanation: This question tests a 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically identifying which observations support a specific claim about gravity. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For gravity, common claims include 'gravity pulls all objects toward Earth,' 'gravity always pulls downward,' or 'gravity acts on all objects.' Evidence must be observable (what we see/measure) and directly relevant to the claim. Reasoning explains the logical connection: 'BECAUSE all dropped objects fall toward ground (evidence), we can conclude that gravity pulls objects toward Earth (claim).' For this question, specific context: evaluating whether observation 'all dropped objects fell toward ground' supports claim 'gravity pulls objects toward Earth' - yes, consistent with claim / identifying which evidence best supports 'gravity pulls on all objects' - would be observation showing different objects (heavy, light, big, small) all fall / explaining how 'water flows downhill' supports 'gravity pulls toward Earth' - water pulled downward by gravity toward Earth. Choice B is correct because it identifies observation that directly demonstrates the claim (if claim is 'gravity pulls all objects,' shows different objects falling). This shows the student understands scientific claims must be supported by evidence and reasoning, not just stated / evidence must directly relate to claim / reasoning connects evidence to claim by explaining relationship / stronger evidence is more direct, consistent, and based on multiple observations / complete argument has claim, evidence, and reasoning. Choice C represents a common error where students confuse description with evidence (restate claim instead of providing observation) / confuse evidence (what we observe) with reasoning (why observation supports claim) / match evidence to wrong claim / choose weak single observation over strong pattern / provide evidence without reasoning, missing connection to claim / state opinion or belief instead of observation / use circular reasoning (claim supports claim) / ignore that evidence could have alternative explanation. This typically happens because 5th graders may not yet clearly distinguish between claim (statement to be supported), evidence (observations), and reasoning (explanation of connection) / students may restate claim thinking they're providing evidence / students may think any observation about falling is evidence for any claim about gravity, missing need for specific relevance / students may not recognize that stronger evidence comes from patterns across multiple observations, not single instance / everyday language doesn't distinguish 'I think' (opinion) from 'I observed' (evidence) so students may blur these / students may provide evidence but forget to explain how it connects to claim. To help students: Explicitly teach and practice Claim-Evidence-Reasoning structure using graphic organizer with three sections / Model identifying each component: 'What is the claim (statement about gravity)? What is the evidence (what did we observe)? What is the reasoning (how does evidence support claim)?' / Practice with multiple examples: present claims, have students identify what evidence would support them / Compare strong and weak evidence: 'One object fell' vs. 'Every object we dropped fell' - which is stronger evidence for 'gravity pulls all objects'? / Use sentence frames: 'Claim: [statement about gravity]. Evidence: [observation or data]. Reasoning: This evidence supports the claim because [explanation].' / Emphasize that evidence must be observable (what we see/measure, not what we think/believe) and must directly relate to claim. Watch for: Students who restate claim when asked for evidence ('Gravity pulls things down' as evidence for 'gravity pulls things down') / Students who provide reasoning when asked for evidence ('because gravity is a force' is not observation) / Students who provide evidence but can't explain how it supports claim (missing reasoning component) / Students who think any observation about gravity is evidence for any claim about gravity / Students who choose single weak observation over consistent pattern / Students who state opinions ('I think gravity is strong') as if they're evidence / Students who can complete teacher-provided argument structure but can't independently identify claim, evidence, and reasoning in text.

Question 15

To support the claim that "Gravity is always acting, even when an object is not moving," a student gives this evidence: "A book resting on a bathroom scale still shows a number."

Which reasoning best connects the evidence to the claim?

The scale number shows the book is being pulled downward, even while it is resting. (correct answer)
The scale number shows the book is colorful and easy to see.
The scale number shows the book wants to move downward by itself.
The scale number shows gravity can be turned off when the book is lifted.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically explaining reasoning that connects evidence to claim. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For this question, the claim states 'gravity is always acting, even when an object is not moving,' and the evidence is 'a book on a scale shows a number.' The reasoning must explain how the scale reading proves gravity is still pulling on the stationary book. Choice A is correct because it provides clear reasoning explaining how evidence logically supports claim - the scale number indicates the book is being pulled downward by gravity even while resting, directly connecting the observation to the claim about gravity always acting. This shows the student understands reasoning must create a logical bridge between evidence and claim. Choice C represents a common error where students use imprecise language that anthropomorphizes objects - saying the book 'wants to move' assigns human desires to an inanimate object rather than explaining the physical force of gravity. This typically happens because everyday language often uses metaphors like 'wants to fall' instead of precise scientific language about forces, and 5th graders may not yet distinguish between these modes of explanation. To help students: Model precise scientific language - 'Gravity pulls the book downward' not 'The book wants to go down.' Use sentence frames for reasoning: 'The evidence shows [observation], which means [connection to claim].' Practice identifying and correcting anthropomorphic language in student explanations. Watch for: Students who use vague or metaphorical language instead of describing forces, students who restate evidence or claim instead of explaining the connection, or students who add incorrect ideas (like gravity being turned off) that weren't part of the original evidence.

Question 16

A student claims, "Gravity always pulls objects downward, toward the ground." During recess, the student observed these events:

A soccer ball rolled down a small hill.
A book slid off a desk and fell to the floor.
A leaf was blown sideways by the wind.
A helium balloon rose to the ceiling.

Which observation provides the strongest evidence for the student's claim?

The leaf was blown sideways by the wind.
A helium balloon rose to the ceiling.
A book slid off a desk and fell to the floor. (correct answer)
The soccer ball rolled down a small hill.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically evaluating whether evidence actually supports claim about gravity's direction. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For this question, the claim states 'gravity always pulls objects downward, toward the ground,' so evidence must show objects moving downward due to gravity, not other forces. Choice C is correct because it identifies observation that directly demonstrates the claim - a book sliding off a desk and falling to the floor shows clear downward motion toward the ground caused by gravity. This shows the student understands evidence must directly demonstrate the specific claim being made. Choice B represents a common error where students select observation that actually contradicts the claim - a helium balloon rising upward appears to go against gravity pulling downward, though actually buoyancy overcomes gravity's downward pull. This typically happens because 5th graders may not yet distinguish between observations that support versus contradict a claim, or may not recognize when other forces are involved. To help students: Practice evaluating whether evidence supports, contradicts, or is unrelated to claims using a three-column sort. Emphasize matching evidence to the specific wording of the claim - 'always pulls downward' means we need examples of downward motion. Discuss how some observations (like helium balloons) involve multiple forces, making them poor evidence for simple gravity claims. Watch for: Students who choose any observation involving motion without considering direction, students who select dramatic or interesting observations (balloon rising) over simple direct evidence, or students who don't recognize when evidence contradicts rather than supports a claim.

Question 17

The observations show these results from a classroom investigation:

When a student dropped a marker, it fell to the floor.
When a student dropped an eraser, it fell to the floor.
When a student dropped a plastic spoon, it fell to the floor.

Which conclusion does this evidence best support?

Gravity pulls objects sideways when they are dropped.
Gravity pulls objects toward Earth when they are released. (correct answer)
Only school supplies are affected by gravity.
Objects fall because they are the same color as the floor.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically constructing evidence-based claims from patterns in observational data. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For this question, students must analyze a pattern where three different objects (marker, eraser, plastic spoon) all fell to the floor and determine what conclusion this evidence supports. Choice B is correct because it constructs a claim that the evidence actually supports - the consistent pattern of different objects falling to the floor when dropped demonstrates that gravity pulls objects toward Earth when released. This shows the student understands how to draw appropriate conclusions that match the scope and nature of the evidence. Choice C represents a common error where students make overly restrictive claims - limiting gravity to 'only school supplies' when the evidence could support a broader claim about gravity acting on objects in general. This typically happens because students may focus on superficial categories (these happen to be school supplies) rather than the underlying pattern (all objects fell), missing the broader principle. To help students: Practice identifying patterns vs. superficial similarities - 'What's important: that these are school supplies, or that they all fell?' Guide students to make claims that match evidence scope - not too narrow or too broad. Discuss how scientists look for underlying patterns, not surface features. Watch for: Students who make claims about unrelated factors (color, sideways motion), students who create unnecessary restrictions based on the specific examples used, or students who miss the consistent pattern focusing on irrelevant details.

Question 18

The data from a class drop test are shown below. Students dropped each object from the same height and watched what happened.

Claim: "Gravity pulls on all objects."

Which observation from the data best supports the claim?

The paper clip was shiny and the sponge was dull.
All five different objects fell downward when released. (correct answer)
Some objects made a louder sound when they hit the floor.
The objects were dropped in the classroom instead of outside.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically identifying which observations support a specific claim about gravity. Scientific arguments require three components: (1) Claim - statement about gravity, (2) Evidence - observations or data from experiments/models, and (3) Reasoning - explanation of how evidence supports claim. For gravity, common claims include 'gravity pulls all objects toward Earth,' 'gravity always pulls downward,' or 'gravity acts on all objects.' Evidence must be observable (what we see/measure) and directly relevant to the claim. For this question, evaluating which observation best supports 'gravity pulls on all objects' requires finding evidence showing multiple different objects being affected by gravity. Choice B is correct because it identifies observation that directly demonstrates the claim - 'all five different objects fell downward' shows gravity acting on multiple objects, providing pattern-based evidence rather than single instance. This shows the student understands scientific claims must be supported by evidence that directly relates to the claim, and stronger evidence comes from patterns across multiple observations. Choice A represents a common error where students select observation that doesn't relate to claim - describing appearance (shiny/dull) has nothing to do with whether gravity pulls on objects. This typically happens because 5th graders may not yet clearly distinguish between any observation about objects and relevant evidence for specific claim about gravity. To help students: Model identifying relevant evidence by asking 'Does this observation show gravity pulling on objects?' for each choice, emphasizing that evidence must directly demonstrate what claim states. Watch for: Students who think any observation about the objects is evidence for claim about gravity, missing need for observations to show gravity's effect (falling/pulling) not just object properties.

Question 19

A student claims, "Gravity always pulls objects downward (toward Earth)." The student used these observations:

When a book was released, it fell to the floor.
Water poured from a cup flowed down into the sink.
A helium balloon floated up to the ceiling.

Does the evidence support the claim? Why or why not?

Yes. Two observations show things move downward when not pushed up by another force. (correct answer)
No. The balloon floated up, so gravity sometimes pulls upward.
No. The book fell because it is heavy, not because of gravity.
Yes. The balloon floated up because gravity is turned off indoors.

Explanation: This question tests 5th grader's ability to support claims about gravity using observations or models (NGSS 5-PS2-1), specifically evaluating whether evidence actually supports claim and explaining reasoning that connects evidence to claim. Scientific arguments require examining whether all evidence is consistent with claim - if claim states 'gravity always pulls downward,' then any upward movement needs explanation. For this question, the helium balloon floating up appears to contradict the claim, but deeper analysis shows balloon is pushed up by buoyancy force stronger than gravity's downward pull. Choice A is correct because it accurately evaluates that evidence does support claim and provides clear reasoning - book and water moving downward directly support claim, while balloon's upward movement is due to another force (buoyancy) overcoming gravity's downward pull, not gravity pulling upward. This shows the student understands that gravity still pulls downward on balloon, but stronger upward force causes net upward movement. Choice B represents a common error where students confuse object's motion with direction of gravity's pull - seeing balloon go up, they conclude gravity must pull upward. This typically happens because 5th graders focus on visible motion rather than understanding multiple forces can act simultaneously, with strongest force determining motion. To help students: Use examples of competing forces like holding book against gravity or wind pushing against walking direction to show that force can act one way while object moves another way due to stronger opposing force. Watch for: Students who think gravity changes direction based on object motion rather than understanding gravity always pulls downward but can be overcome by stronger forces.

Question 20

Two students gave arguments about gravity.

Student 2:
Claim: "Gravity pulls objects toward Earth."
Evidence: "My favorite ball falls when I drop it."
Reasoning: "Gravity is strong, so it makes the ball fall."

Which argument is better supported by evidence, and why?

Student 2, because one example is enough to prove a claim.
Student 1, because it uses many observations and connects them to the claim. (correct answer)
Student 2, because it uses the word "strong," which is scientific evidence.
Student 1, because dropping objects only works if the objects are the same size.
