Students were tasked with completing their lab report Introduction sections and creating a graph of their data.  Previously, students were instructed to write their own Introduction sections.  However, given the time constraints, students were encouraged to collaborate today and create one strong Introduction section per lab group.   Prior to collaborating, students reviewed one particularly strong Introduction section written by one of my students.  After completing Introduction paragraphs, students worked with their lab partners to create at least one graph of their data.  Many students used class time to work on the classroom computers, with encouragement to use Microsoft Excel as the graphing program.
