In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure. Learners will be surprised to see what...

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads. Since we do not typically feel atmospheric pressure, this activity allows...

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the...

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere. Learners...

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 quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind. Use this...

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle. Learners lay the two cans parallel to each other on a level surface...
