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 activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

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

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

In this activity, learners follow a recipe to create play dough scented with fruit-flavored drink mix.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

In this activity, learners make a stroboscope--a spinning disk with slits around the edge that you look through.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

In this activity, learners make a Benham Top to explore visual illusions and optics.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

In this activity (15th activity on the page) about the sense of touch, learners use glue and cardboard to construct a maze they use with their eyes closed.

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