In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

Learners and their families celebrate and recognize the importance of making healthy choices every day by participating in a health fair.

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
