This experiment is designed to illustrate how fluids, including water, have the ability to flow.

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

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

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

In this activity (p.26 of PDF), learners discover why mushrooms have spots. Learners use a balloon, toilet paper, and water to simulate what happens as mushrooms grow.

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

In this activity (page 13 of the PDF), learners discover how weathering and erosion change the Earth’s surface.

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

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 geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

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.
