This project is ideal for regular or advanced high school geometry courses. It teaches numerical approximation methods for finding volume of an irregularly shaped object, and is a great critical thinking challenge. This project also connects to Calculus, as it is essentially volume by slices of known cross section. It also requires organization, as students are asked to record the relevant measurements they collect. The project guide includes instructions for a written lab report, which is an excellent way to develop written reasoning skills and incorporate technology. My students have loved this project!
