Image Scaling is an important first step that all astronomers perform in understanding image-type data produced by satellites and telescopes. Each activity in this booklet has an image. The physical size of the object shown in the image is listed in the activity. Students measure the size of the image and divide the physical size by the image size to determine the scale factor. They can then use the scale factor to investigate sizes of objects within the image. Each word problem has background information about the image. The one-page assignments are accompanied by one-page answer keys. The “Extras for Experts” section is a set of problems for students who want a challenge.
