In this activity, learners discover a brain process called habituation.

In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.

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

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

In this activity about depth perception, learners create an optical illusion in a shoe box.

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

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

In this activity, learners will use their nose to sniff out hidden scents using extracts and cotton balls. Activity includes materials list, game instructions, STEM connections and more.

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

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 online game, learners practice memory recall. They are shown a collage of pictures for two minutes, then have to write down everything they remember and check how they did.

In this quick activity/demonstration (5th on the page), learners explore depth perception.

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 will make a thaumatrope, an old-fashioned optical illusion that dates back to the 1820s.

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

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

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

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.
