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.

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

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

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

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 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.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

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 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 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 oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

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 chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.
