\subsubsection{Lab assignments}  After completing the short in-class exercise, students use the rest of the lab period to work on their lab, with their groups and the assistance of circulating instructors. Students are not expected to complete their labs during the lab period, but have the necessary software on their own laptops to complete the labs at home or in additional lab group study sessions. Students usually have one week to complete the lab, and submit them via Dropbox on D2L.  The lab assignments in AST 208 have been completely rewritten over the past two years. The lab now seeks to communicate learning goals through authentic research experiences, using the tools astronomers regularly use (Python, DS9, observatory archives). A central goal of the lab is to foster independence in our students, in both defining and tackling problems. For this reason, labs are often perceived as very open-ended and loosely defined, and instructors will often direct students towards google rather than handing out cleanly-defined documents containing the answer. Another goal of lab is to communicate what astronomy is like as a career, and how the science of astronomy is accomplished. We discuss telescope proposals, graduate school, career paths, and current research questions.   Here are some examples of current AST 208 labs (see also Fig.\ \ref{fig:hst}):\\
