In this activity, learners replicate the scientific processes of observing, forming an explanation, revising and communicating about a model of a comet. Learners construct a model of features of a comet using an assortment of common craft supplies.... (View More)

In this lesson, learners will discover how certain snakes (pit-vipers) can find prey using a natural infrared sensor and will extend their understandings by exploring infrared technology applications. The lesson features background information for... (View More)

In this multi-day activity, students use infrared and visible images of animals and sort them into broad categories based upon the learner's own reasoning and observations of the images. Further explorations reveal that warm and cold-blooded animals... (View More)

In this introductory activity, learners investigate and discuss infrared images of various everyday objects, such as toasters, hairdryers, and running water, to learn about infrared imaging. Student questions about the false-color images help guide... (View More)

This is a lesson about using gravity to assist in spacecraft navigation. Learners will relate an elastic collision to the change in a satellite's or spacecraft's speed and direction resulting from a planetary fly-by, often called a "gravity assist"... (View More)
