Big Idea: Changing ecosystems are maintained by natural processes.

Mussels are a kind of invertebrate that filter food out of the water they live in. This makes them a great tool for monitoring environmental water quality and tracking bioaccumulation in aquatic food webs.

A study on bird feeders and beak sizes shows how an everyday human activity can affect the evolution of another species.

Do an experiment with celery to learn about the structures that help plants take up water.

You can make your own terrarium for growing plants!

When a species ends up outside of its natural zone, the consequences on other species, ecosystems and human industries can be severe. Climate change and human activities can introduce species into new zones.

How do different populations adapt to their environment? Let’s explore this concept through guppy speciation.

Arctic animals have evolved to thrive in harsh arctic ecosystems, but the environmental footprint created by climate change is affecting their survival.
