The goal of this lesson is for two groups of students to exchange information (e.g., through poster presentations, Podcasts, debates, or PowerPoint presentations) about how two different theories explain a natural phenomenon: Newton's Law of... (View More) Gravitation and Einstein's General Theory of Relativity. The lesson will also illustrate how the scientific process allows a new, more complete theory to take the place of an older theory that does not produce accurate results for a new discovery. Students will need to have either studied both Newton's Law of Gravitation and Einstein's Theory of Relativity or be given the time and resources to look up this information. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1919 Cosmic Times Poster. (View Less)

In this activity, identified on the Infrared Zoo website as Lesson 3, students explore the Cool Cosmos Infrared Zoo database and investigate the differences between warm and cold-blooded animals. As a result, students discover how infrared imagery... (View More) provides biologists/zoologists detailed information on how warm-blooded and cold-blooded animals thermoregulate. This lesson features background information for the teacher, background information for students, a mini-exploration of Infrared Image Technology, image sets, assessment information, student worksheets, extension and transfer activities, and additional resources.

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) and infrared light images. As a result, students discover that the relative temperature of water from a geyser, as well as the nearby landscape, is revealed in the infrared images. This lesson features background information for the teacher, background information for students, a mini-exploration of Infrared Image Technology, image sets, assessment information, student worksheets, extension and transfer activities, and additional resources.
