In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

In this quick activity, learners explore static electricity using a plastic comb, wool cloth, puffed rice, and a plastic bag.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners discover a trick to release the air out of a balloon without popping it.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.

In this activity, learners electrically plate zinc onto brass objects.
