In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

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

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

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

In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

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

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

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

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

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

In this activity, learners discover how solar energy can be used to heat water.

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

In this activity, learners explore the different heating properties of soil and water.

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