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) This activity relates to several NASA comet missions such as Deep Impact, Stardust, Stardust-NExT, and EPOXI and can be used to emulate a process that scientists and engineers follow on all missions.

Learners can read about the Deep Impact mission to encounter comet Tempel 1, including the mission, the experiment, results, the comet, the team, and how the results were transmitted back to Earth. Includes pre- and post-encounter fact sheets.
Learners will take and then compare the images taken by a camera - to learn about focal length (and its effects on field of view), resolution, and ultimately how cameras take close-up pictures of far away objects. Finally, they will apply this... (View More) knowledge to the images of comet Tempel 1 taken by two different spacecraft with three different cameras, in this case Deep Impact and those expected/obtained from Stardust-NExT. This lesson could easily be adapted for use with images from other NASA missions. (View Less)
