In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity, learners play with a fuzzy-colored dot that has no distinct edges seems to disappear. As learners stare at the dot, its color appears to blend with the colors surrounding it.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t

With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

This is an activity to do when there is a solar eclipse!

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.

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.

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.

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

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

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.

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

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.
