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

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

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

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 fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

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.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
