The Exploratorium

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

If you had a long tube with a 5 millimeter wide slit, would you see the entire Golden Gate Bridge?

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 activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.
