All questions
Question 1
Look at the evidence. What evidence shows the spider changed the space?
- A web appeared, and next day an insect was caught. (correct answer)
- Spiders have eight legs, so they can catch food.
- The corner was dark, so a web grew there.
Explanation: We look for evidence of change. First a web appeared in the corner. Next day an insect was caught.
Question 2
Look at the evidence. How do we know ants changed the ground?
- Photos show a dirt mound growing bigger each week. (correct answer)
- Ants are tiny, so they can live anywhere.
- It rained, so dirt piles appeared by themselves.
Explanation: We need evidence of change. The photos show the dirt mound. It got bigger each week.
Question 3
Look at the evidence. What shows the beaver changed the stream?
Claim: Beaver changed the stream to meet a safety need.
Evidence 1 (Before photo): A shallow, fast stream; no pond.
Evidence 2 (During photo): Jamal saw a beaver carrying sticks and mud.
Evidence 3 (After photo): A dam blocks water; a deep pond formed.
Evidence 4 (Observation): Beaver swims to a lodge in the pond.
- We saw the beaver swim, so it must like water.
- Before and after photos show no dam, then a dam and pond. (correct answer)
- The stream was cold, so the beaver built a warm home.
- Jamal thinks beavers are smart, so they changed the stream.
Explanation: This question tests kindergarten understanding of using evidence to support explanations of how organisms change environment to meet needs (K-ESS2-2: Construct an argument supported by evidence for how plants and animals including humans can change the environment to meet their needs). An evidence-based explanation uses observations, photos, measurements, or other documentation to support a claim. For environmental change: Claim: [Organism] changed [environment] to meet [need]. Evidence: What we observed (saw beaver building dam, photographed before/after, measured pond depth, watched bird gathering twigs, found holes in ground, saw organism using structure). Reasoning: How evidence connects to claim (photos show dam was built, observations prove beaver did it, seeing beaver safe in pond shows need met). Multiple pieces of evidence make explanation stronger. Kindergarteners learn: we need evidence (not just guesses) to support explanations, evidence comes from observations and documentation, evidence shows what happened and helps explain why. In this example, the claim is beaver changed the stream to meet a safety need. Evidence provided includes: Evidence 1 (Before photo): A shallow, fast stream; no pond; Evidence 2 (During photo): Jamal saw a beaver carrying sticks and mud; Evidence 3 (After photo): A dam blocks water; a deep pond formed; Evidence 4 (Observation): Beaver swims to a lodge in the pond. Specific evidence: before picture shows shallow stream, during observation shows beaver working, after picture shows dam and pond, observation shows beaver using it for safety. The evidence supports that beaver built a dam which helped meet safety needs. Choice B is correct because it identifies actual evidence documented in stimulus by citing before and after photos showing the change from no dam to a dam and pond. The answer cites specific evidence: photos showing before and after, which directly supports the explanation that beaver changed the stream to meet safety needs. The answer shows understanding that evidence is what we can observe/document, multiple evidence pieces strengthen explanation, evidence must support the claim. Choice A is incorrect because it states claim without evidence, citing an observation but adding a guess ('must like water') instead of documented change. Kindergarteners often state conclusions without saying how we know or confuse what happened (claim) with how we know (evidence). To help students use evidence to support explanations: Teach claim-evidence-reasoning framework simplified: 'What happened? How do we know? Why does it matter?' Practice with beaver example: Claim: 'Beaver changed stream to pond.' How do we know? (Evidence): 'We have photos showing stream before and pond after. We observed beaver cutting trees and piling sticks. We measured pond - it's deeper now than stream was.' Why does it matter? (Reasoning): 'Deep pond keeps beaver safe from predators. The change helped beaver meet its safety need.' Emphasize evidence types kindergarteners can collect: Photos/pictures (before and after), observations (what we saw), measurements (counted, measured with ruler/thermometer), sequences (day 1, day 2, day 3 showing progression). Practice identifying: 'Is this evidence or just a guess? What photos do we have? What did we observe?' Create evidence charts: Claim at top, evidence boxes listing each piece (Photo 1, Observation 2, Measurement 3), reasoning connecting evidence to claim. Use sentence starters: 'We know [organism] changed environment because we [observed/photographed/measured]...' or 'Evidence shows... We saw... This tells us...' Compare strong vs weak evidence: Strong = specific observable documentation ('Photo shows dam built'). Weak = vague ('Something happened'). Watch for: students who state conclusions without evidence, those who confuse evidence with opinions ('I think' vs 'We observed'), or those who don't connect evidence to explanation. Build skill: collect multiple pieces of evidence, document observations, use evidence to support explanations about what organisms do and why.
Question 4
Look at the evidence. How do we know the squirrel changed the ground?
- We saw new holes and watched the squirrel bury acorns. (correct answer)
- Squirrels have fluffy tails, so they can dig holes.
- We saw snow in winter, so the squirrel made the snow.
Explanation: This tests finding proof of change. The correct answer shows what we watched - new holes and the squirrel burying acorns. This is evidence we can see.
Question 5
What evidence shows the woodpecker changed the tree for a nest?
- We heard pecking, saw wood chips, and the hole got bigger. (correct answer)
- Woodpeckers are loud birds, so trees must have holes.
- The tree was tall, so the woodpecker felt happy there.
Explanation: We need evidence of the woodpecker's work. The correct answer tells us what we heard and saw. We heard pecking sounds, saw wood chips falling, and watched the hole get bigger.
Question 6
Look at the evidence. What shows the beaver changed the stream?
- Before water was shallow; after a dam, a deep pond formed. (correct answer)
- The beaver was brown and had a flat tail.
- It might rain later, so the stream could get deeper.
Explanation: We need evidence that shows change. The correct answer tells us what was different before and after. The water was shallow, then the beaver made a dam and it became deep.
Question 7
Look at the evidence. How do we know a child changed the yard?
- We saw grass before, then dug soil, then plants, then vegetables eaten. (correct answer)
- The child likes vegetables, so the yard became a garden.
- We saw clouds over the yard, so plants grew by themselves.
- We saw a rainbow, so the yard changed by itself.
Explanation: The evidence shows grass first, then dug soil, then plants, then vegetables to eat, which shows the child changed the yard.
Question 8
Look at the evidence. Which shows the beaver changed water for safety?
- We saw fish in the stream, so the beaver must be safe.
- We saw the beaver cut sticks, then a dam, then a pond and lodge. (correct answer)
- Beavers like swimming, so the stream probably changed itself.
Explanation: We look for evidence of change for safety. The right answer shows all the beaver's actions in order. We saw it cut sticks, build a dam, make a pond, and build a lodge home.
Question 9
Use the evidence to explain how the spider changed its space.
- We saw an empty corner, then a web, then an insect caught. (correct answer)
- Spiders are scary, so they probably make webs everywhere.
- The spider is small, so it could not change anything.
Explanation: We need evidence that shows change. The correct answer tells us what we saw happen step by step. First the corner was empty, then we saw a web, then an insect got caught.
Question 10
Look at the evidence. What shows the woodpecker changed the tree?
- We heard pecking, saw wood chips, and the hole grew bigger. (correct answer)
- Woodpeckers have beaks, so trees always have holes.
- We saw a squirrel, so the squirrel made the hole.
Explanation: This asks for evidence of change. The right answer tells what we heard and saw - pecking, wood chips, and a bigger hole. This shows the woodpecker changed the tree.
Question 11
Look at the evidence. Which proof shows the beaver needed safety?
- Before photo shows beaver on land near a fox. (correct answer)
- Beavers have big teeth, so they are never in danger.
- After photo shows clouds, so the beaver made the sky.
Explanation: This tests finding evidence of need. The correct answer describes the before photo - beaver on land near a fox. This shows danger and need for safety.
Question 12
Look at the evidence. What shows the squirrel changed the ground?
Claim: Squirrel changed the ground to meet winter food needs.
Evidence 1 (Day 1 photo): Chen saw a squirrel carrying acorns.
Evidence 2 (Day 3 observation): New small holes in the dirt.
Evidence 3 (Day 7 map): Three spots marked where acorns were buried.
Evidence 4 (Winter photo): Squirrel digs and eats an acorn.
- The squirrel ran fast, so it changed the ground.
- We saw holes and a map, but no squirrel using them.
- Photos and observations show acorns carried, buried, then dug up later. (correct answer)
- Acorns are tasty, so squirrels always have enough food.
Explanation: This question tests kindergarten understanding of using evidence to support explanations of how organisms change environment to meet needs (K-ESS2-2: Construct an argument supported by evidence for how plants and animals including humans can change the environment to meet their needs). An evidence-based explanation uses observations, photos, measurements, or other documentation to support a claim. For environmental change: Claim: [Organism] changed [environment] to meet [need].

Evidence provided includes: Evidence 1 (Day 1 photo): Chen saw a squirrel carrying acorns; Evidence 2 (Day 3 observation): New small holes in the dirt; Evidence 3 (Day 7 map): Three spots marked where acorns were buried; Evidence 4 (Winter photo): Squirrel digs and eats an acorn. Specific evidence: photo shows squirrel carrying acorns, observation shows holes, map marks burial spots, winter photo shows digging up acorns. The evidence supports that squirrel dug holes which helped meet food needs. Choice C is correct because it lists multiple pieces of evidence and connects them to the explanation by describing photos and observations of acorns carried, buried, then dug up. The answer cites specific evidence: photos showing before and after actions, observations of change, results showing need met, which directly supports the explanation that squirrel changed the ground to meet winter food needs. The answer shows understanding that multiple evidence pieces strengthen explanation and evidence must support the claim. Choice A is incorrect because it gives irrelevant observations like squirrel running fast without citing documented evidence of change. Kindergarteners often think any observation counts as evidence even if doesn't support claim or state opinions not evidence. To help students use evidence to support explanations: Teach claim-evidence-reasoning framework simplified: 'What happened? How do we know? Why does it matter?' Practice with beaver example: Claim: 'Beaver changed stream to pond.' How do we know? (Evidence): 'We have photos showing stream before and pond after.

Question 13
Use the evidence. Which proof shows the bird changed the branch?
Claim: Bird changed a branch to meet nesting needs.
Evidence 1 (Before): No nest on the branch.
Evidence 2 (During): Maya watched the bird place twigs.
Evidence 3 (After): Nest is on the branch.
Evidence 4 (Result): Chicks hatch in the nest.
- Maya watched twigs placed, and later saw a nest with chicks. (correct answer)
- Birds can fly, so a nest will appear on any branch.
- The branch moved in wind, so the nest built itself.
- The bird is small, so it cannot change a branch.
Explanation: This question tests kindergarten understanding of using evidence to support explanations of how organisms change environment to meet needs (K-ESS2-2: Construct an argument supported by evidence for how plants and animals including humans can change the environment to meet their needs). An evidence-based explanation uses observations, photos, measurements, or other documentation to support a claim. For environmental change: Claim: [Organism] changed [environment] to meet [need].

Evidence provided includes: Evidence 1 (Before): No nest on the branch; Evidence 2 (During): Maya watched the bird place twigs; Evidence 3 (After): Nest is on the branch; Evidence 4 (Result): Chicks hatch in the nest. Specific evidence: before shows no nest, during observation shows bird working, after shows completed nest, result shows chicks hatching. The evidence supports that bird built a nest which helped meet nesting needs. Choice A is correct because it identifies actual evidence like Maya watched twigs placed, and later saw a nest with chicks. The answer cites specific evidence: observations showing during and result, which directly supports the explanation that bird changed the branch to meet nesting needs. The answer shows understanding that evidence is what we can observe/document, multiple evidence pieces strengthen explanation, evidence must support the claim. Choice B is incorrect because it states claim without evidence and gives general fact like birds can fly without documented change. Kindergarteners often confuse what happened (claim) with how we know (evidence) or give irrelevant details. To help students use evidence to support explanations: Teach claim-evidence-reasoning framework simplified: 'What happened? How do we know? Why does it matter?'

Question 14
Look at the evidence. What shows ants changed the ground surface?
- Photos show a mound grew bigger each week near the crack. (correct answer)
- Ants are tiny, so they always make big hills.
- We saw a bird fly over, so ants made a nest in trees.
Explanation: This asks for evidence of change. The right answer uses photos that show the mound growing bigger. This proves the ants changed the ground.
Question 15
Look at the evidence. What does it show about the squirrel?
- We saw new holes and later the squirrel dug up acorns. (correct answer)
- The squirrel has a fluffy tail, so it stores food.
- We heard birds singing, so the squirrel buried acorns.
Explanation: We look for evidence about the squirrel. We saw new holes in the ground. Later the squirrel dug up acorns there.
Question 16
Look at the evidence. What shows ants changed the ground surface?
Claim: Ants changed the ground to meet colony needs.
Evidence 1 (Week 1 photo): Flat crack in pavement, no dirt pile.
Evidence 2 (Week 2 photo): Small dirt pile appears.
Evidence 3 (Week 3 observation): Amir watched ants carrying dirt out.
Evidence 4 (Week 4 photo): Big ant mound is built.
- The pavement is gray, so ants made a mound.
- Photos show a dirt pile growing bigger each week into a mound. (correct answer)
- Amir saw ants, but we did not see any dirt change.
- Ants are tiny, so they cannot change the ground.
Explanation: This question tests kindergarten understanding of using evidence to support explanations of how organisms change environment to meet needs (K-ESS2-2: Construct an argument supported by evidence for how plants and animals including humans can change the environment to meet their needs).

Specific evidence: week 1 photo shows no pile, week 2 shows small pile, observation shows ants working, week 4 shows completed mound. The evidence supports that ants built a mound which helped meet colony needs. Choice B is correct because it identifies actual evidence documented in stimulus by describing photos showing a dirt pile growing bigger each week into a mound. The answer cites specific evidence: photos showing sequence of change, which directly supports the explanation that ants changed the ground surface to meet colony needs. The answer shows understanding that evidence is what we can observe/document, multiple evidence pieces strengthen explanation, evidence must support the claim. Choice A is incorrect because it cites things not documented and gives irrelevant observations like pavement color without evidence of change. Kindergarteners often give one small observation when multiple strong evidence available or confuse claim with evidence. To help students use evidence to support explanations: Teach claim-evidence-reasoning framework simplified: 'What happened? How do we know? Why does it matter?' Practice with beaver example: Claim: 'Beaver changed stream to pond.' How do we know? (Evidence): 'We have photos showing stream before and pond after.

Question 17
Look at the evidence. How do we know the spider changed the space?
- We saw an empty corner, then a web with an insect. (correct answer)
- Spiders are scary, so they must make webs everywhere.
- We saw rain, so the spider filled the air with water.
Explanation: This tests finding evidence. The correct answer tells what we saw - first an empty corner, then a web with an insect. This shows the spider changed the space.
Question 18
Look at the evidence. How do we know the gopher changed the ground?
- The grass is green, so a gopher must live there.
- A dirt mound appeared, and we saw the gopher enter a hole. (correct answer)
- We think the burrow is cozy, so the gopher dug it.
Explanation: We need evidence of change. A dirt mound appeared on the ground. We saw the gopher enter a hole.
Question 19
Look at the evidence. How do we know the child changed the yard?
- We saw digging, planting seeds, and later vegetables picked to eat. (correct answer)
- The child likes green, so plants grew by themselves.
- We saw a dog nearby, so the dog planted the garden.
Explanation: This tests finding evidence. The correct answer lists what we saw - digging, planting, and picking vegetables. This proves the child changed the yard.
Question 20
Look at the evidence. What shows the bird changed the tree?
- We saw the bird building, then a nest with eggs appeared. (correct answer)
- The bird is small, so it must live in a nest.
- We heard thunder, so the nest must have fallen down.
Explanation: This asks about evidence of change. The right answer tells what we saw - the bird building and then eggs in a nest. This shows the bird changed the tree.
