10. Experiment description We are investigating the correlation between known air pollutants and water pollutants in Lake Michigan. First, we will launch electronics in the rocket containing several gas sensors, a camera, and a GPS unit. The gas sensors will take continuous data on the concentrations of various pollutants at various altitudes. The camera will take photos from the nosecone of the rocket during its descent. The GPS will be used to track the location of the rocket for recovery. We will then travel by boat along the route provided by the GPS in order to collect 100mL water samples of Lake Michigan. One sample will be collected every 50 feet. The water samples will be analyzed for pollution content by mass spectrometry.

11. Payload Description The gas sensors circuit board was designed with help from the Madison West SLI team Helios. The circuit includes sensors that detect concentration of CH 4 (methane), O 3 (ozone), CO 2 (carbon dioxide), and CO (carbon monoxide). The data will be processed by four Parallax Propeller processors and stored in the form of flash memory. The altitude will be calculated by an altimeter on the board.
