Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

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.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.
