Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

This is a series of demonstrations about different electrical and magnetic phenomena.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

In this activity, learners explore the parts of a circuit by modeling, as a group, a “human” circuit.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity, learners use simple materials to build their own compass.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.
