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

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

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

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.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

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

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

In this experiment, learners float colored ice cubes in hot and cold water.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

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

In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.
