In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

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

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

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

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 activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

In this activity related to flight, learners conduct two simple tests to explore how lift works.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.
