In this activity (on pages 29-35), learners examine water pollution and filtration.

In this outdoor activity, learners design devices that will catch prey or gather plants.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.
