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 will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

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 outdoor activity, learners measure familiar objects in nature to practice working with the metric system.

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