My Precalculus class is predominantly focused on graphing. We graph polynomials, exponential functions, logarithmic functions, rational functions and trigonometric functions. In each chapter, we do labs involving regression equations such as motion of a ball on a ramp, parabolic shape of a water fountain, exponential graph of the bounce height of a ball, sinusoidal regression of a bouncing spring or swinging pendulum.
At the end of the year, this project puts it all together using data that interests the students. The students choose the data, research the history of the data, decide which regression equation best models the data and then use the trendline to predict the future. They create a six slide PowerPoint and present their project to the class. The project is perfect for the end of school when class life is hectic with students taking AP tests and state End-of-Course exams.
Included are directions for the project and the PowerPoint presentation, a rubric for scoring and sample presentations. Enjoy!
