K-ESS2-2
The standard
Construct an argument supported by evidence for how plants and animals (including humans) can change the environment to meet their needs.
Next Generation Science Standards
What this standard means
Students need to explain that living things can change the places around them so they can get food, water, shelter, or space. They should use simple evidence from observations, pictures, or read-alouds, not just say what they think. Examples can include people building homes, beavers making dams, roots lifting sidewalks, or worms mixing soil.
Mastery sounds like, “The squirrel digs a hole because it needs a safe place for food. I know because I saw the hole and the acorn.” Students often get stuck naming needs without explaining the change, or giving opinions without evidence.
Ways to teach it
- Hands-on: Give pairs soil trays, plastic worms, sticks, and toy animals to model how one living thing changes its space to meet a need.
- Prompt: Show a photo of tree roots cracking pavement and ask, “What changed, who caused it, and what need might it help?”
- Quick assessment: Students draw one plant or animal changing its environment and label the change, the need, and one piece of evidence.
- Real-world connection: Take a schoolyard walk to find ant hills, nests, roots, worn paths, or human-built shade and discuss what needs they meet.
