I need ideas for a Math Project (science related)?
posted by Olive .
So I was given a math project in which we need to gather "real world information" and make a scatter plot of the info. With this we must graph a line, parabola and exponential curve of best fit then find those formulas. The math is straight forward but I can't decide on a topic. I wanted to do something along the lines of electromagnetic radiation but I don't really care at this point. I just really want something in the science field. Any suggestions from anybody?

Why not measure the voltage output of a solar cell as a function of angle to the sun?
Data you would need is voltage max( cell panel facing sun), then voltage at several (many) angles to the sun.
It should correlate to a scatter plot fitting as best a cosine curve.
Solar cells are cheap, and available at Radio shack. You will need a voltmeter, and something to measure angles with, pencil, paper.
