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

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 math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

Use this hands-on activity to demonstrate infrared and thermal radiation.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
