Propeller-driven thrusters maneuver ROV Hercules above the seafloor. Students will design rubberband-powered thrusters to race as fast as possible along a zipline track. Documenting and comparing designs challenges groups to identify the most successful solutions. Use this module as an inquiry-driven introduction to forces and motion or to the engineering design process. The module includes animations of ROV thrusters and a basic construction timelapse video for educators or younger students.
Objectives & learning outcomes
- practice the engineering design process.
- discuss the basics of propulsion using STEM vocabulary.
- produce a thruster model powered by a rubber band and propellor to race down a racetrack as fast as possible.
- understand how modifications to their design produce changes in the speed it can move.
