The Standard

Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.

What This Standard Means

What Students Need to Do

Students examine an organism's needs and traits, then compare them with the food, water, shelter, space, and conditions in one habitat. They use observations or provided facts to make and support a claim about how likely that organism is to live there.

What Mastery Looks Like

Students make a clear claim for several organisms and cite relevant evidence from both the organism and habitat. They explain the link, such as thick fur helping in cold conditions or gills requiring water for breathing.

Common Misconceptions

Students may decide based only on where they have seen an animal. They may treat survival as all or nothing, rather than recognizing that limited food, shelter, or water can reduce success. They may also assume any organism can adjust to any habitat.

How to Assess It

Exit ticket: A habitat is cold and snowy, with buried seeds and no ponds. Decide whether an animal with thick fur, one with thin fur, and one with gills would live well, less well, or not at all, then support each decision with one fact.

Ways to Teach It

  1. Build three habitat trays with sand, water, and leaf litter, then place organism models and justify each placement with a trait.

  2. Write: Could a pond frog live in a dry desert? Support your claim with two facts about frogs and deserts.

  3. Play Habitat Match with organism and habitat cards, earning a point only when the match includes a spoken evidence statement.

  4. Study photos of a local park, list available food and shelter, then predict which three local animals are most likely to live there.
