Make two firefly lanterns, then program them to blink to one another and change colors.

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.

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

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
