See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

This is a game that is sure to sharpen players' basic math skills. Players must use four randomly selected numbers to create an equation that equals a fifth number.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

Balance a ball in the air with a hair dryer! This Exploratorium produced activity shows learners concepts like lift and air streams. You can try many different angles, speeds, and ball types.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

In this activity, learners will learn how igneous rock, metamorphic rock, and sedimentary rock are formed as part of the rock cycle and that the same forces that produce/change rocks also produce/chan

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

In this activity, learners find the answer to the question, "if you have a pile of 8 cards, and you remove half, then half again, how many times can you do this until you get to just one card?" This w

This activity (9th activity on the page) about hearing demonstrates to learners the importance of having two ears.

In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

The goal of this activity is to design, build and test a house or toy for an animal.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

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.

If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.
