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.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this interactive game, learners will test their memory of animal and insect sounds. Flip over cards, listen to the sound, and try to find the ones that match.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

This game depicts a woman going through her day, faced with various loud sounds.

This game plays a dozen different sounds, altered to simulate what they would sound like if you had hearing loss.

In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

Use this hands-on activity to demonstrate infrared and thermal radiation.

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
