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.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

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 discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

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

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

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

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

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

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity, learners explore how salt water freezes in comparison to fresh water.

This activity was designed for blind learners, but all types of learners can use it to investigate how different materials vary in their conduction of heat.
