The featured curriculum is part 4 of a 4-part series exploring the different impacts of climate change. This section focuses on climate change and ecosystems. The goal is to have students research the interdependencies among plants and animals in an ecosystem and explore how climate change might affect those interdependencies and the ecosystem as a whole.

The activity requires students not only to gain a general understanding of ecosystems and climate change, but also to apply that knowledge to a local ecosystem, looking at the changes that have occurred and also forming hypotheses about future changes, and thinking about how to test those hypotheses.
