This lab activity has students making the connection between energy, the conservation of energy, work, and power. The lesson provides enough guidance to help students without directly stating what procedural steps to follow. This allows students to develop their own computational models During the lab, students will need to run or walk up stairs so that they can compute a change in gravitational potential energy, which will also be equal to the work done in raising their mass up the height of the stairs. By simply timing their ascent, the students can then calculate their power. In the end, students are to calculate how many stairs they would need to climb to burn off the calories in an Oreo cookie.
The lesson comes complete with a warm up activity, notes to the instructor, an example of student work, and a wrap up activity.
