- 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.
Answer: Photos and observations show acorns carried, buried, then dug up later.
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 squirrel changed the ground to meet winter food needs. 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. 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.

Specific evidence: morning shows empty, afternoon shows spider working, next morning shows completed web, day 2 shows web in use for food. The evidence supports that spider built a web which helped meet food needs. Choice A is correct because it connects evidence to explanation by describing we saw a web made, then an insect caught for spider food. The answer cites specific evidence: observations and photos showing progression and result, which directly supports the explanation that spider changed the space to meet food 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 gives irrelevant observations like spider color without documented evidence of change or connection to need.
