The Exploratorium

Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.

In this activity, learners will explore globes of frozen water to learn how to ask and then answer 'investigable' questions. The activity web page includes a short video demonstration.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

Your tongue can sense about 6 different flavors (salty, sweet, bitter, sour, umami/savory, and fat), but your nose provides a lot more "taste" information than you realize when you eat.

In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.

In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.
