In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

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.

In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners create their own weather forecast map.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this activity, learners discover that sand is the major ingredient in glass.
