Students will perform quadratic regression on the calculator and compare the resulting equation to the model P = I2R they had calculated by hand. Outline: Record the data points in a table with current as the independent variable and power as the dependent variable. Store and graph the data points on a graphing calculator.

You can use your calculator to find a Power Regression equation the same way you used it to find a Linear Regression equation. For example: A period of a pendulum is the time required for one oscillation. An experiment is conducted in which pendulums are created with different lengths, l, and the corresponding periods are recorded.
