This lesson provides a way for students to determine the relationship between the distance from a light source and its brightness. Once students discover the relationship, they can begin to understand how astronomers use this knowledge to determine... (View More)

In this investigation, students use "point-source" light, light meters, and graphing software to quantify the reduction in light over distance. Through careful measurement of light received at several distances, students discover the best fit of the... (View More)

This is an educators guide to accompany the Journey to the Stars planetarium show. The materials for grades 9-12 include suggestions for activities to do before and after viewing the planetarium show, including class discussions about units of... (View More)

In this lesson, students will read the 1919 edition of the Cosmic Times (see related resources) and respond by raising questions to be answered with further research. They will make a model of curved space to view the motion of spheres as explained... (View More)

This booklet introduces electromagnetic waves, their behaviors, and how scientists visualize these data. Each region of the spectrum is described and illustrated with examples of NASA science. It is a companion piece to the video series under the... (View More)

In this multi-day activity, identified on the Infrared Yellowstone website as Lesson 1, students use observation skills to determine what information can be gathered from images taken in both visible and infrared light. Students compare the visible... (View More)

This is a lesson about the shape of objects in space. Learners will observe the surface of rotating potatoes to help them understand how astronomers use variations in reflective brightness to determine the shape of asteroids.

This is a hands-on lab activity about the properties and states of water. Learners will complete activities using different liquids to understand the three states of matter, explain how the high heat capacity and abundance of liquid water makes life... (View More)

Students are introduced to classification through progressive activities. Initially, the teacher models the task by classifying buttons. Students then devise a classification scheme for paper clips. Subsequent activities use objects brought from... (View More)
