In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.

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.

Did you know that you would be a different age if you lived on Mars? It's true!

In this activity, learners explore center of gravity, or balance point, of stacked blocks.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

In this activity, learners explore their eye pupils and how they change.

In this activity, learners use simple materials to create giant bubbles.

In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

Did you know that a Slinky makes a handy model of earthquake waves?

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

In this activity about light and perception, learners create pictures in thin air.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.

In this activity, learners explore the invisible infrared radiation from an electric heater.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
