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.

In this activity, learners discover if carbon dioxide has an effect on temperature.

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

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

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 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 activity, learners explore the devices used over time to measure changes in temperature.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

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

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

In this activity, learners explore Charles' Law in a syringe.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

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

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.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

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