In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

In this activity, you'll make an electric motor--a simple version of the electric motors found in toys, tools, and appliances everywhere.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

In this activity about electricity, learners explore what happens when you blow a fuse.

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

In this activity, learners investigate sound and vibration by making a "bee hummer"--a toy that sounds like a swarm of buzzing bees when you spin it around.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

In this activity, learners make their own heat waves in an aquarium.
