The Exploratorium

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

Are there boxes, is this an illusion, or is this real life Q-bert? Illusions are always fun to build especially when you can build them.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

Experience a spinning spiral...you won't be hypnotized, but you'll see what happens when you look away. It's like getting off a merry-go-round and everything keeps moving.

This is a great activity about human energy production. Learners will work out with a clothespin to investigate why hockey players jump on a stationary bike after an intense game.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.
