In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

En esta actividad, los aprendices usarán la lógica para ganar un juego. Dos personas toman turnos quitando uno o dos "cuerdas" de las estacas en el suelo.

En esta actividad sobre la densidad de los líquidos, los participantes ven si las gotas de colorante se hunden en diferentes soluciones de agua.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

In this activity, learners conduct the "Stroop Effect" test and explore what happens when they try to complete two simple tasks at the same time.

During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

En esta actividad, los aprendices harán un terrario usando materiales simples.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
