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

In this activity, learners investigate procedural memory.

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 (1st on the page), learners keep a "SLOG" or Sleep Log to study their sleep patterns.

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

In this activity about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

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.

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

In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

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

In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

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.

In this outdoor activity, learners play a game of Tag to discover how neurons attach themselves to each other to form a chain.

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.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.
