In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing

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

If you had a long tube with a 5 millimeter wide slit, would you see the entire Golden Gate Bridge?

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners conduct a simple test to find their blind spot.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this game (4th activity on the page) about hearing, learners test their ability to identify various sounds without looking.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity, learners investigate procedural memory.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

This activity (9th activity on the page) about hearing demonstrates to learners the importance of having two ears.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

Learners use two mirrors to explore how images of images of images can repeat forever.

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

In this fun and imaginative writing assignment (page nine of the pdf), students will flex the creative side of their brains to learn more about the laws of motion and the scientific process.
