In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

This is an activity about inertia, Newton's First Law of Motion. Learners will discover how an egg at rest, or any object at rest, stays that way.

In two separate bags, learners mix water with Epsom salts and detergent.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.
