This is a variation of the activity originally located at:

(Observing Images of the Solar System)

1. From the linked pages, choose three images to evaluate in detail, and an additional 8-10 images to sort into groups (you may do more images if you wish). Suggestion: choose images that seem to have been taken in the same way (B&W, or color; and from similar points of view).

2. List the three images (by number) and describe what you see in them.(CP participants: turn in these descriptions as part of your homework.)

3. Using the 8-10 (or more) images you have chosen, sort them into groups. You may need to try several arrangements before you find one that satisfies you. There is no right answer, but some groupings may give clues to some underlying science. Try to find groupings that tell you something about the worlds or features of the worlds, or that lead you to questions you might be able to investigate further. "Camera angle" is not an inherent feature of a world.

4. CP participants: turn in your groupings as part of your homework, using the following format for each group:

Designation of the group

(These can be letters or numbers, or something more descriptive name.)

Members of the group

(List images by number.)

Criteria used to determine the members of a group

(Please describe these so that someone else, given the criteria and the images, could re-create your groups.)


(If you think your groups show some underlying science, or if you need to justify the placement of an image that's questionable, you may do so here.)
