What do we do when the power is down and the lights go out? This module expands on this real-life situation to let students explore the basics of chemical generation of electricity by exploring practical chemistry and designing their own emergency battery and LED light. Moving beyond the typical qualitative lemon battery experiment, students engage in a team design project to systematically investigate the electrochemical properties of different metals and common household electrolytes (vinegar and lemons, but also coke, coffee, salt and Smarties!) that could be used to make a emergency battery to power a night light. This data is then used by the teams to design and optimize batteries that can power an LED emergency light for several nights.
This workshop is sponsored by the PSU College of Engineering/MESA and the Lemelson Foundation. Participating teachers will receive a set of integrated curriculum materials (slides, worksheets, resources) and a full set of matching classroom supplies to support teaching the module, and an opportunity to join a cohort of supportive colleagues.
Presenters are Mihir Ravel, Cary Sneider and Jennifer Wells, research faculty at Portland State University.
