Reflection: Performance Tasks Poppers Investigation - Section 4: Closing


This lesson can serve as a summative assessment for the poppers unit. For many students, the poppers unit is their first exposure to the process of conducting a scientific investigation on a self-generated testable question. For this reason, when assessing student progress using their lab report, I look for progress, not mastery. I want students to gain an understanding of each step of the scientific process and to understand the basic function of a controlled experiment. I do not expect students to present sophisticated conclusions or rationales for their decision making process. Instead, I assess students on their participation, ability to safely conduct their investigation, and check to make sure that all sections of the lab report are complete. If you use student portfolios, this lab write-up can serve as an effective artifact to show student growth between their first investigation and subsequent efforts.
