In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
