This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners make a photographic image--without a camera!

How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners can observe chaotic motion. A magnet tied to a piece of string makes a pendulum, which swings over three sets of fixed magnets.

In this activity, learners follow simple directions to explore and create platonic solids.

In this activity, learners make a photographic image—without a camera!

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 activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

In this activity, learners will build a ball run contraption.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.
