Understanding Non-Linear Rates of Change

The lesson focuses on understanding the average rate of change, particularly in a geometry context. Students are instructed to watch a video of a cone being filled with water to observe how the rate of change in water height varies. The lesson includes exercises to calculate the volume of a cone and determine the time required to fill it at a constant rate. Students are guided to graph the rate of change and analyze the results. The lesson concludes with additional exercises and a summary of the key concepts learned.
