Instructional Ideas

  • Invite an engineer to discuss centripetal acceleration
Classroom Considerations

  • Learners should have some basic mathematics and physics knowledge, such as being able to use the equations for angular velocity and centripetal acceleration
  • Activity requires a variety of materials; see materials list for more information

  • Directions are clear and include pictures
  • Provides a list of vocabulary terms with their definitions

  • Without robotics kit and software, the activity cannot be performed as written
