Biodiversity and Human Impact Worksheets and Activities

In the earliest grades, students begin by identifying basic needs of plants and animals and recognizing that living things live in habitats that provide food, water, and shelter. As they move through grades 2-3, they explore simple food chains, how changes in habitats affect organisms, and the concept of endangered species. By grades 4-5, students investigate ecosystems more deeply, examining food webs, the effects of pollution and deforestation, and conservation strategies. Related concepts include interdependence, adaptation, extinction, renewable and nonrenewable resources, and human impact on land, water, and air.

Our resources build skills such as observing, classifying, comparing, cause-and-effect reasoning, and using evidence to support claims. Across the grade range, students practice reading informational texts, analyzing data, and communicating scientific ideas. The progression ensures that foundational ideas are reinforced while complexity increases, preparing students for middle school science.
