Applications of Cosine Curves

Students will have to read the assigned articles and video first to get an idea of what a power factor, watt, and the power grid is.  Next, they will conduct an experiment of three different light bulbs to determine what their power factor is, the temperature, and the amount of watts being used.  The students will have to learn how to use a device safely to record all of this. They will have to determine which lightbulb is the most effective for the power grid. Once the students have learned about the power factor, they should use their prior knowledge to graph a cosine function.
