Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this fun and interactive online exhibit, the straight lines of a tile wall appear to curve. The learner moves the rows of tiles and changes the color of the grout to achieve the intriguing effect.

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device.

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

In this activity about electricity, learners suspend pieces of tape from a straw to construct an electroscope, a device that detects an electrical charge.

When baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back.

In this online activity exploring our perception of "cuteness," learners adjust various factors (like pupil size or length of limbs) on a face, a cat, and a hammer.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.

Sound can travel through a variety of media.

In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.

This activity shows learners (with adult supervision) how to make a Glitter Globe, a fabulous toy that shimmers when you shake it.

In this activity, learners make a stroboscope--a spinning disk with slits around the edge that you look through.

In this online version of the classic paper and pencil game, learners practice looking ahead to anticipate an opponent's move.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
