In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.

In this activity, learners investigate circulation and measure their own your heartbeat. A heart rate, or pulse, is the number of times the heart beats per minute.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

In this activity, learners will test soil content using their sample, some water and a container that seals.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

We don't normally view people upside down and so our brains aren't accustomed to it.

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

In this activity, learners discover how hard their hearts work to pump blood.

In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

Can you deceive your eyes? When your eyes work normally, you see a nice 3 dimensional picture, but what happens when each eye sees something different?

This is a quick and simple demonstration about reflexes (second activity on the page).

This perception trick focuses on conflicting information to the brain...instead of trying to see two images, you're trying to get a bright spot by overlapping the image you see through two tubes.
