In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).

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.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

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 quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

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.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

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 use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
