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 outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

Many people get water from a source deep underground, called groundwater.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

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

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