The lessons in this unit demonstrate the imaging process of astronomical satellites such as the Hubble Space Telescope. The Magic Wand activity shows how images can be divided and reassembled. The Color activity shows how astronomy satellites collect color data and how that data can be reassembled on the ground. The Binary Number and Paint by the Numbers activities familiarize students with the process of data transmission to Earth and its re-assembly into images. Reproducible student sheets are included.
