What This Standard Means
What Students Need to Do
- Students build a model of a local ecosystem, such as a pond or school garden. They use it to show how a change, such as drought or pesticide use, could affect plants and animals.
What Mastery Looks Like
- A student can show how plants, animals, water, and food connect in a model. When one part changes, they can trace a likely effect to another part and explain why it might happen.
Common Misconceptions
- Students may think losing one kind of animal affects only that animal. They may also treat a model as an exact forecast rather than a way to explain what could happen.
How to Assess It
- Give students this prompt: “A school garden has fewer insects after pesticide is sprayed. Draw plants, insects, and birds, then use your model to predict one effect on the birds.”

Ways to Teach It
Give groups plant, insect, and bird cards to connect with string, then remove the insect cards and have them explain what changes.
Ask partners to use a pond diagram to answer, “If the water drops, how might frogs be affected, and why?”
Hand out drought and pesticide event cards; students take turns changing a garden model and explaining one predicted effect.
Compare photos of a local garden before and after a dry spell, then mark likely changes to plants and insects on a diagram.
