Question 1

Canada geese: flying alone, 60% reach the destination and 30% die; in a V-formation, 90% reach the destination and they take turns in front. Which argument best uses the evidence to show flocks help geese survive?

  1. Geese survive better alone because only 60% reach the destination, which is higher than 90%.
  2. Flocks help geese survive because 90% reach the destination in V-formation, and taking turns in front helps them not get as exhausted. (correct answer)
  3. Geese fly in a V because it looks cool in the sky.
  4. In V-formation, 90% reach the destination and they take turns at the front.
Explanation: This question tests constructing arguments about Canada geese flock benefits (3-LS2-1). Students must create an argument with CLAIM, EVIDENCE, and REASONING about group survival advantages. The data shows that 90% of geese reach their destination in V-formation versus only 60% flying alone, and they take turns at the front position. Answer B correctly argues that flocks help survival by citing the 90% success rate and explaining how taking turns prevents exhaustion, which connects the behavior to survival. Answer A incorrectly interprets the data (60% is lower, not higher than 90%), C lacks evidence and scientific reasoning, and D only lists facts without argument structure. When teaching, emphasize reading data carefully and explaining mechanisms: not just that more geese survive in flocks, but WHY (energy conservation through turn-taking). Practice connecting specific behaviors to survival outcomes.

Question 2

Lion data: alone catches prey 15%, eats every 4 days, loses 20% body weight; pride of 5 catches prey 40%, all eat every 2 days, stay healthy; pride chases away hyenas and protects cubs. Construct an argument using the data to explain why prides help survival.

  1. Pride lions eat every 4 days, so they get less food than lions alone. (correct answer)
  2. Lions survive better in prides because they are the kings of the jungle.
  3. A single lioness loses 20% body weight.
  4. Pride life helps lions survive because the pride catches prey 40% of hunts (more than 15% alone), so lions eat every 2 days and stay healthy, and the pride can chase away hyenas and protect cubs, keeping more lions alive.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The lion data shows that alone, a lioness catches prey 15% of the time, eats every 4 days, and loses weight, while a pride catches 40%, eats every 2 days, stays healthy, and protects from hyenas and for cubs, showing enhanced nutrition and security in groups. The correct answer, choice A, works well because it states the claim that pride life helps lions survive, cites specific evidence like better catch rates and protection, and explains how these maintain health and life. Distractors fail, such as choice B using irrelevant titles, choice C being only evidence, and choice D stating incorrect eating frequencies. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like cub protection. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 3

Honeybee data: single bee builds nest in 10 days, stores food 5 days, 0 offspring survive winter; colony of 10,000 builds hive in 2 days, stores food 6 months, queen lays 1000 eggs, 5000 survive winter, and defends from wasps. Which argument best uses the evidence to show groups help honeybees survive?

  1. Single bees store food for 6 months, so they survive winter just as well as colonies. (correct answer)
  2. Bees live in colonies because colonies are big.
  3. A colony builds a hive in 2 days and stores food for 6 months.
  4. Bee colonies help survival because 10,000 bees build a hive in 2 days and store food for 6 months, and 5000 bees survive winter, while a single bee stores only 5 days of food and has 0 offspring survive, so the group has more food and protection.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The honeybee data shows that a single bee builds a nest in 10 days, stores food for only 5 days, and has 0 offspring survive winter, while a colony of 10,000 builds a hive in 2 days, stores food for 6 months, has the queen lay 1000 eggs with 5000 surviving winter, and defends from wasps, highlighting better resource storage and protection in groups. The correct answer, choice A, works well because it states the claim that bee colonies help survival, cites specific evidence like faster hive building and higher winter survival, and explains how these provide more food and protection. Distractors fail, such as choice B being only evidence without a claim or reasoning, choice C being a vague claim, and choice D using wrong data on food storage. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like increased offspring survival. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 4

Canada geese data: flying alone, 60% reach destination and 30% die; in a V-formation flock, 90% reach destination, they take turns at the front, and help injured geese. What evidence best supports the claim that groups help geese survive?

  1. Groups help geese survive because 90% in a V-formation reach the destination compared to 60% alone, and taking turns and helping injured geese means fewer get too tired or die.
  2. Geese survive better in groups because flying is fun with others. (correct answer)
  3. Geese in flocks honk loudly during migration.
  4. Flying alone is best because more geese reach the destination alone than in a flock.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The Canada geese data shows that flying alone, 60% reach the destination with 30% dying, while in a V-formation flock, 90% reach the destination as they take turns at the front and help injured geese, reducing exhaustion and deaths. The correct answer, choice B, works well because it states the claim that groups help geese survive, cites specific evidence like higher success rates and turn-taking, and explains how these mean fewer geese get tired or die. Distractors fail, such as choice A being only an observation without claim or reasoning, choice C using opinion, and choice D stating incorrect data on success rates. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like reduced fatigue. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 5

Wild dog data: alone catches prey 10% and travels 20 km daily; pack of 8 catches prey 50% and travels 10 km; adults bring food to pups and defend territory. Which argument best uses the evidence to show packs help survival?

  1. A pack of 8 travels 10 km daily. (correct answer)
  2. Packs help wild dogs survive because adults bring food to pups, packs catch prey 50% (not 10% alone), and they defend territory, so more dogs get food and stay protected.
  3. Packs help wild dogs survive because wild dogs can run fast.
  4. Packs make survival worse because packs catch prey only 5% of the time.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The wild dog data shows that alone, dogs catch prey 10% of the time and travel 20 km daily, while a pack of 8 catches 50%, travels 10 km, with adults bringing food to pups and defending territory, demonstrating improved hunting and protection in groups. The correct answer, choice A, works well because it states the claim that packs help wild dogs survive, cites specific evidence like higher catch rates and defense, and explains how these ensure more food and safety. Distractors fail, such as choice B using irrelevant facts, choice C being only evidence, and choice D stating wrong catch rates. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like better territory defense. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 6

Honeybee data: single bee builds nest in 10 days, stores food 5 days, 0 offspring survive winter; colony of 10,000 builds hive in 2 days, stores food 6 months, queen lays 1000 eggs, 5000 survive winter, and defends from wasps. Which is the strongest argument for colony benefits?

  1. Colonies help bees survive because they can defend the hive from wasps and store food longer, and the data shows 5000 bees survive winter in a colony while 0 offspring survive when a bee is alone. (correct answer)
  2. A single bee stores food for 6 months, so colonies are not needed.
  3. Bees should live in colonies because colonies are busy.
  4. A single bee builds a nest in 10 days.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The honeybee data shows that a single bee stores food for 5 days with 0 offspring surviving winter, while a colony stores for 6 months, defends from wasps, and has 5000 survive winter, indicating superior defense and resource management in groups. The correct answer, choice A, works well because it states the claim that colonies help bees survive, cites specific evidence like longer food storage and winter survival rates, and explains how these provide protection and sustenance. Distractors fail, such as choice B being a vague opinion, choice C being irrelevant evidence, and choice D using incorrect food storage data. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like hive defense. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 7

Zebra evidence: lone zebra was caught and killed; herd of 50 ran together, stripes confused lion, lion gave up; herd lookouts spotted predators early. Use the evidence to argue that herd behavior helps survival.

  1. Zebra herds help zebras survive because a lone zebra was killed, but in a herd of 50 the lion got confused by many moving stripes and gave up, and lookouts spot predators early so the herd can run away sooner. (correct answer)
  2. Lone zebras are safer than herds because the lion always gives up on lone zebras.
  3. A zebra herd has lookouts and stripes.
  4. Zebras survive in herds because herds are big.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The zebra evidence shows that a lone zebra was caught and killed, while a herd of 50 ran together confusing the lion with stripes leading it to give up, and lookouts spotted predators early, illustrating enhanced escape and detection in groups. The correct answer, choice A, works well because it states the claim that zebra herds help survival, cites specific evidence like stripe confusion and early spotting, and explains how these allow the herd to run away sooner and survive. Distractors fail, such as choice B being a vague claim without evidence, choice C listing features without reasoning, and choice D stating incorrect safety comparisons. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like better predator avoidance. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 8

Lion data: one lioness catches prey 15% of hunts, eats every 4 days, and loses 20% body weight; a pride of 5 catches prey 40%, all eat every 2 days, and stay healthy; the pride also chases away hyenas and protects cubs. Which argument best uses the evidence to show groups help lions survive?

  1. A pride catches prey 40% of hunts and eats every 2 days.
  2. Lions survive better alone because a single lioness can hunt by herself.
  3. Lion prides help survival because the pride catches prey more often (40% vs 15%), so lions eat every 2 days and stay healthy, and the pride can chase away hyenas and protect cubs, which keeps more lions alive. (correct answer)
  4. Lion prides help survival because lions like being together.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The lion data shows that a single lioness catches prey 15% of hunts, eats every 4 days, and loses 20% body weight, while a pride of 5 catches prey 40%, eats every 2 days, stays healthy, and chases away hyenas while protecting cubs, showing better hunting and protection in groups. The correct answer, choice C, works well because it states the claim that lion prides help survival, cites specific evidence like higher catch rates and defense, and explains how these keep lions healthy and alive. Distractors fail, such as choice A arguing incorrectly against groups, choice B being only evidence, and choice D using opinion without data. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like regular meals. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 9

Wild dog data: alone catches prey 10% and travels 20 km daily; pack of 8 catches prey 50% and travels 10 km; adults bring food to pups and defend territory. Which is the strongest argument for group benefits?

  1. Alone wild dogs catch prey 60% of the time, so groups are not needed.
  2. Wild dogs survive better in packs because a pack of 8 catches prey 50% of the time (not 10% alone), travels less, and adults bring food to pups and defend territory, so more dogs eat and stay safe. (correct answer)
  3. Packs help wild dogs survive because they travel 10 km a day and alone dogs travel 20 km.
  4. Wild dogs should be in packs because I think being with friends is better.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about how being in a group helps animals survive. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The wild dog data shows that alone, dogs catch prey 10% of the time and travel 20 km daily, while a pack of 8 catches prey 50% of the time, travels only 10 km, and adults bring food to pups while defending territory, indicating better food access and safety in groups. The correct answer, choice B, works well because it states the claim that wild dogs survive better in packs, cites specific evidence like higher catch rates and less travel, and explains how these lead to more dogs eating and staying safe. Distractors fail, such as choice A misusing travel data to suggest packs are worse, choice C relying on opinion without evidence, and choice D stating incorrect prey catch rates. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows benefits like improved hunting success. Practice by having students build arguments for different animals, identifying the claim first, then finding matching evidence, and explaining the connection to survival advantages.

Question 10

Use this data to argue why wild dogs survive better in packs than alone.

  1. Wild dogs survive better alone because a single dog catches prey 50% of the time and travels only 10 km each day.
  2. Packs help wild dogs survive because a pack of 8 catches large prey 50% of the time (vs 10% alone), travels less, and adults bring food to pups, so more dogs get fed and live. (correct answer)
  3. A pack of 8 catches large prey 50% of the time and travels 10 km daily.
  4. Wild dogs like being in packs because it feels safe.
Explanation: This question assesses constructing arguments about group survival benefits (3-LS2-1). A complete argument must have: CLAIM (packs help wild dogs survive), EVIDENCE (data comparing pack vs. alone performance), and REASONING (explaining how evidence proves the claim). The data shows packs of 8 catch large prey 50% of the time versus only 10% when alone, travel less distance daily, and adults bring food to pups. Answer B is correct because it presents all three components: states the claim about pack survival benefits, cites specific comparative data (50% vs 10% hunting success, less travel, food sharing), and explains how this helps survival (more dogs get fed and live). Answer A incorrectly interprets the data by claiming dogs survive better alone, Answer C only lists facts without making an argument, and Answer D provides no evidence just an opinion about feelings. To teach this skill effectively, have students practice identifying claims first ("packs help survival"), then finding supporting evidence in data tables or observations, and finally connecting evidence to survival outcomes using "because" statements.

Question 11

What evidence best supports the claim that zebra herds help zebras survive lion attacks?

  1. Zebras in herds eat grass together.
  2. A herd is always exactly 100 zebras, so lions cannot count them.
  3. Zebras have stripes that look nice.
  4. In a herd of 50, the lion got confused by many moving stripes and gave up, but a lone zebra was caught and killed. (correct answer)
Explanation: Students must identify evidence supporting the claim that zebra herds help survive lion attacks (3-LS2-1). When constructing arguments, evidence must directly show how groups provide survival benefits compared to being alone. The question asks specifically for evidence, not a complete argument. Choice B provides the best evidence by showing the contrast: a herd of 50 confused the lion with moving stripes causing it to give up (survival), while a lone zebra was caught and killed (death). Choice A describes appearance without survival connection, Choice C mentions behavior unrelated to lion attacks, and Choice D provides false information about herd size. To teach evidence selection, have students sort observations into "helps explain survival" and "doesn't help explain survival" categories, focusing on outcomes (escaped vs caught) rather than just descriptions. Practice identifying comparison evidence that shows group advantage versus individual disadvantage.

Question 12

Zebras: in a herd, lookouts spot predators early; a lone zebra was caught and killed. Use the evidence to argue that herd behavior helps survival. Which argument is best?

  1. Herds help zebras survive because lookouts can spot lions early and the herd can run together, so zebras have a better chance to escape than a lone zebra. (correct answer)
  2. Zebras survive in herds because zebras have stripes.
  3. A lone zebra was caught and killed, and herds have lookouts.
  4. Herds make zebras run slower, so lions can catch them more easily.
Explanation: This question tests constructing arguments about zebra herd survival advantages (3-LS2-1). Students must build an argument using CLAIM, EVIDENCE, and REASONING based on the provided observations. The evidence shows herds have lookouts that spot predators early, contrasted with a lone zebra being caught and killed. Answer A provides the best argument by claiming herds help survival, citing both the lookout behavior and the lone zebra's fate, then reasoning that early warning and group running improve escape chances. Answer B lacks evidence and proper reasoning, C only lists facts without making an argument, and D argues against the claim incorrectly. To teach this skill, emphasize how protective behaviors (like having lookouts) connect to survival outcomes. Practice identifying cause-and-effect relationships: lookouts spot danger → herd runs together → better escape chances → improved survival.

Question 13

Geese observations: in V-formation, geese take turns leading and help injured geese. Which argument best shows a survival benefit of flying in a flock?​

  1. Geese in a flock survive better because taking turns leading lets geese rest, and helping injured geese keeps more of them alive to reach the destination. (correct answer)
  2. Geese should fly in a flock because it makes a letter V in the sky.
  3. Geese take turns leading and sometimes help injured geese.
  4. Geese survive better alone because a flock makes them too crowded to fly.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about the benefits of animals living in groups for survival. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The stimulus provides geese observations: in V-formation, geese take turns leading and help injured ones, reducing fatigue and aiding recovery. The correct answer, choice A, works well because it states the claim that geese survive better in flocks, cites specific evidence like turn-taking and helping injured, and explains how this allows rest and keeps more alive. Distractors fail because choice B is vague without evidence, choice C only lists observations without a claim or reasoning, and choice D makes an incorrect claim favoring solitary flying. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows better survival outcomes. Practice by having students build arguments from multiple animal examples, identifying each part and discussing why incomplete arguments are weaker.

Question 14

Which argument best uses honeybee data to show colonies help bees survive winter?

  1. A colony of 10,000 builds a hive in 2 days and stores food for 6 months.
  2. Bees should live alone because one bee can build a nest in 10 days.
  3. Bee colonies help survival because the colony stores food for 6 months and 5,000 bees survive winter, but a single bee stores 5 days and 0 survive. (correct answer)
  4. Colonies are best because bees like being busy together.
Explanation: Students must construct arguments about how bee colonies help survival using winter survival data (3-LS2-1). A complete argument includes a CLAIM that colonies help survival, EVIDENCE from the data, and REASONING explaining the connection. The data shows colonies store food for 6 months with 5,000 bees surviving winter, while single bees store only 5 days of food with 0 surviving. Choice C correctly argues that colonies help survival, cites both pieces of comparative evidence (6 months vs 5 days storage, 5,000 vs 0 survivors), and connects this to survival. Choice A only lists colony facts without making an argument, Choice B incorrectly argues against group living, and Choice D provides no evidence. To teach this skill, use comparison charts showing group vs individual data, then guide students to identify which numbers show better survival and explain why (more food storage means surviving food shortages, more survivors means the strategy works).

Question 15

Bee data: single bee stores food 5 days and 0 offspring survive winter; colony stores food 6 months and 5000 survive. Which argument best supports group survival?​

  1. A colony stores food for 6 months and 5000 bees survive winter.
  2. Bee colonies help survival because 10,000 bees store food for 6 months and 5000 survive winter, but a single bee stores only 5 days and none survive, so working together helps them live through winter. (correct answer)
  3. Bees should live alone because building a small nest in 10 days is safer than a hive.
  4. Bee colonies are better because they look cooler and have more space to fly.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about the benefits of animals living in groups for survival. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The stimulus provides bee data: a single bee stores food for only 5 days with no offspring surviving winter, while a colony of 10,000 stores for 6 months and 5000 survive, demonstrating better resource storage in groups. The correct answer, choice B, works well because it states the claim that bee colonies help survival, cites specific evidence like the food storage durations and survival numbers, and explains how working together allows them to live through winter. Distractors fail because choice A only lists data without a claim or reasoning, choice C makes an incorrect claim favoring solitary living, and choice D is vague without evidence or survival connection. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows better survival outcomes. Practice by having students build arguments from multiple animal examples, identifying each part and discussing why incomplete arguments are weaker.

Question 16

Which argument best uses geese data (60% alone reach; 90% in V-formation reach) to show groups help survival?

  1. Flocks help geese survive because 90% reach the destination in V-formation, while only 60% reach it alone, so flying together helps them save energy and avoid dying. (correct answer)
  2. Geese should fly alone because 90% reach the destination alone.
  3. Geese in flocks reach the same place, so it does not matter how they fly.
  4. Many geese fly south when it gets cold.
Explanation: This question assesses constructing arguments about goose flock survival benefits using migration success data (3-LS2-1). Effective arguments include a CLAIM about group benefits, EVIDENCE comparing success rates, and REASONING linking evidence to survival. The data shows 60% of lone geese reach their destination while 90% in V-formation succeed. Choice C provides the complete argument: claims flocks help survival, cites both success rates showing 30% improvement in groups, and reasons that flying together saves energy and prevents death during migration. Choice A misreads the data claiming 90% succeed alone, Choice B incorrectly states outcomes are the same, and Choice D provides information without making an argument. Teaching strategy: Use percentage bars to visualize 60% vs 90% success, discuss what happens to the 40% vs 10% that don't reach destination (death/exhaustion), then practice constructing arguments that explain how higher success rates mean better survival.

Question 17

Which argument best uses the lion data to show prides help lions survive?

  1. Lions should live alone because one lioness only catches prey 15% of hunts.
  2. Pride life helps lions survive because a pride catches prey 40% of hunts, so they eat every 2 days and stay healthy. (correct answer)
  3. A pride of 5 lionesses catches prey 40% of hunts and eats every 2 days.
  4. Lions in prides are better because it feels safer to have friends.
Explanation: This question tests 3rd grade students' ability to construct arguments about how groups help animals survive (3-LS2-1). A strong argument needs three parts: a CLAIM that groups help survival, EVIDENCE from the data provided, and REASONING that explains how the evidence supports the claim. The stimulus shows that a pride of lions catches prey 40% of hunts and eats every 2 days, while a lone lioness only catches prey 15% of hunts. Choice B correctly includes all three parts: it makes the claim that pride life helps lions survive, cites the specific evidence that prides catch prey 40% of hunts, and provides reasoning that this means they eat every 2 days and stay healthy. Choice A incorrectly argues against group living, Choice C only states facts without making an argument, and Choice D provides no evidence from the data. To teach this skill, use the C-E-R framework: have students first identify their claim, then find evidence in the data, and finally explain the connection between evidence and survival.

Question 18

Zebra observations: lone zebra was caught; herd of 50 escaped and had lookouts. Which argument best uses evidence?

  1. A lone zebra escaped because its stripes confused the lion, so groups are not needed.
  2. Zebras survive better in herds because one lone zebra was caught, but a herd of 50 ran together, confused the lion's attack, and lookouts spotted danger early, so more zebras escape predators. (correct answer)
  3. Zebras should live in herds because herds are big and zebras like being together.
  4. The herd had 50 zebras and they ran together when the lion attacked.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about the benefits of animals living in groups for survival. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The stimulus provides observations of zebras: a lone zebra was caught by a predator, while a herd of 50 escaped with the help of lookouts spotting danger early. The correct answer, choice A, works well because it states the claim that zebras survive better in herds, cites specific evidence like the lone zebra being caught versus the herd confusing the lion and using lookouts, and explains how this leads to more zebras escaping predators. Distractors fail because choice B is vague without evidence or reasoning, choice C only restates evidence without a claim or explanation, and choice D makes an incorrect claim that groups are not needed based on misleading information. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows better survival outcomes. Practice by having students build arguments from multiple animal examples, identifying each part and discussing why incomplete arguments are weaker.

Question 19

Which argument best uses the geese migration data to show flocks help survival?

  1. Geese should fly alone because it is quieter.
  2. Flocks help geese survive because 90% reach the destination in V-formation, and they take turns in front so fewer get exhausted and die. (correct answer)
  3. Flocks help geese survive because geese are nicer when they share the sky.
  4. Geese in V-formation take turns at the front and help injured geese.
Explanation: Students must construct arguments about how goose flocks help survival during migration (3-LS2-1). Effective arguments include a CLAIM about group benefits, EVIDENCE from migration data, and REASONING explaining how evidence supports survival. The data shows 90% of geese in V-formation reach their destination, and they take turns leading to reduce exhaustion. Choice B correctly claims flocks help survival, provides specific evidence (90% reach destination, taking turns prevents exhaustion), and reasons that this prevents death during migration. Choice A incorrectly argues against flocking, Choice C lists behaviors without making an argument, and Choice D uses emotional reasoning instead of evidence. To teach this skill, use the C-E-R framework with sentence starters: "My claim is...", "The evidence shows...", "This helps survival because..." Practice identifying survival-related evidence (reaching destination, avoiding exhaustion) versus non-survival observations.

Question 20

Bee data: single bee stores food 5 days and 0 offspring survive winter; colony stores food 6 months and 5000 survive. Which argument best supports group survival?

  1. Bees should live alone because building a small nest in 10 days is safer than a hive.
  2. Bee colonies help survival because 10,000 bees store food for 6 months and 5000 survive winter, but a single bee stores only 5 days and none survive, so working together helps them live through winter. (correct answer)
  3. A colony stores food for 6 months and 5000 bees survive winter.
  4. Bee colonies are better because they look cooler and have more space to fly.
Explanation: The skill being assessed is 3-LS2-1, which involves constructing arguments about the benefits of animals living in groups for survival. A strong argument includes a claim that groups help animals survive, evidence from data or observations in the stimulus, and reasoning that explains how the evidence supports the claim. The stimulus provides bee data: a single bee stores food for only 5 days with no offspring surviving winter, while a colony of 10,000 stores for 6 months and 5000 survive, demonstrating better resource storage in groups. The correct answer, choice B, works well because it states the claim that bee colonies help survival, cites specific evidence like the food storage durations and survival numbers, and explains how working together allows them to live through winter. Distractors fail because choice A only lists data without a claim or reasoning, choice C makes an incorrect claim favoring solitary living, and choice D is vague without evidence or survival connection. To teach this, introduce the C-E-R structure: start with a Claim like 'groups help survival,' support it with Evidence from the data, and add Reasoning to connect how the evidence shows better survival outcomes. Practice by having students build arguments from multiple animal examples, identifying each part and discussing why incomplete arguments are weaker.
