In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.

In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

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 activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

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 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 activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.

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

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.
