Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.

In this activity, learners investigate the properties of graphene and graphite.

In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

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.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

In this activity, learners control the (apparent) size of a hole with their brain.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.
