In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners make their own heat waves in an aquarium.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

In this activity, learners discover that our hands are not reliable thermometers.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

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 activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.
