Learners follow a three-step process to start their own rock collection.

In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

In this activity, learners build an instrument for catching and observing flies. Learners act as entomologists, attract flies into a jar using a slice of apple, and then observe the flies' behavior.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
