Launch –¬†It’s time to take off!

These activities are designed to take no more than three class periods and involve the discovery of an astronomy or engineering concept using SDSS data. For example, in the activity Launch РStar Color, students use their Preflight training in filters (Preflight РFilters) to discover the nature of a magnitude scale and the need for multiple filter measurements to compare star colors.

The Launch section itself is structured to support the development of an accurate mental model of the Universe. Launch activities are grouped in order of distance from Earth. 



Launch to SDSS

Let’s start here on Earth exploring the SDSS itself. This section enables students to explore the SDSS telescope, its associated instruments, and how data are stored and retrieved.
