This is an activity about observation. Learners will make a 3-dimensional model of a mock planetary surface inside a box, and then place a lid on top. They will then introduce a simple probe, such as a pencil or stick, at various points through regularly-placed holes in the box top to touch the surface below. Then, they will record the depth at which the probe descends, using the data to make a contour map of its surface. This will help learners see how scientists can research objects which are not easily studied strictly by visual means. This is Activity C-7 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which is available for purchase.
