This is a new twist on a familiar Science Olympiad event. By combining two possible outcomes, it allows students to make choices in an inquiry format. Students must think about materials, Newton’s first and second laws of motion, kinetic energy, and acceleration. Prior to doing this activity, students need to understand the following physical science concepts: changes in speed and direction are indicative of acceleration, the relationship between the application of a force and the resulting change in position and motion on an object, and the important features of the process of scientific inquiry.
