This module designed for middle school students uses simple, fun experiments to introduce some tools and concepts of astronomers. Students are asked to consider how astronomers answer questions like: How old is the Universe? How far away is a galaxy? What are stars made of? The exercise includes working with a simple spectrometer. This unit may be easily modified for other students.
