  1. PhysicsWheeled and levitating vehicles STEM Box Challenge Launch, 22.10.13 Dr Stephen Gibson, Lecturer in Physics

  2. Physics challenge overview: Phase one, Wheeled Vehicles • Farthestdistance travelled. • Fastestvehicle over a set distance. • Fattest(heaviest) load pulled over a set distance. Challenge your students: • Using only the items in the box and your ingenuity, design a self-powered, wheeled vehicle that is powered by an elastic band or a balloon. • Experimentally test which power source to choose and optimise the vehicle differently to compete in three challenges:

  3. Physics challenge overview: Phase one, Wheeled Vehicles • Mechanical piece for vehicle construction: 4 wheels, chassis pieces,/ straws. axles, bearings. • Power sources; elastic bands of different strengths / sizes, including spares; balloons + straws. • Small weights for testing elastic band extension. • Document showing outline of vehicle construction • Worksheet with ideas for experiment test and vehicle optimisation What’s in the box? • Box include the essentials to construct your vehicles:

  4. Physics challenge overview: Phase one, Wheeled Vehicles Some vehicle ideas: • The design is up to your students, but must use one of the power sources provided. • The challenge is how to optimize the design for the three different tasks: • Think about vehicle mass, acceleration, stored energy, speed of release…

  5. Physics challenge overview: Phase II, compete at RHUL + levitation! • On completing the challenges at your school, enter your vehicle in a summer competition at Royal Holloway, University of London. • In the final challenge, make your vehicles levitate with a little help from our liquid nitrogen cooled superconductors and watch it take off and soar along a magnetic track.

  6. Curriculum links • stored (potential) energy in the elastic band or balloon and conversion of energy to other forms (kinetic + heat). • kinematics: time, distance, speed and acceleration. • forces, motion and reducing friction. • Students learning outcomes are linked to the most recent Key Stage 3 curriculum: • Aim to bring the concepts to life through the practical demonstrations! • No knowledge of superconductors is needed…

  7. Added value: • Royal Holloway will support your school with two contact/interface sessions: • Interface 1: Initial skype meeting with teacher / pupils regarding the wheeled vehicle challenges in the competition. • Explain challenge and give pointers on optimising the models for the three challenges. • Interface 2: School visit to include demonstration with liquid nitrogen, to test static levitation with a short test track.

  8. Added value: • Superconductors manufactured via the crystal growth facility in the RHUL Physics. • Diamagnetic (pyrolytic graphite) can be used for static levitation demonstration. • We’ll also provide a magnetically levitating racetrack for the competition at RHUL. • A glimpse of what’s possible: • Superconducting / low temperature technology support through Royal Holloway Physics Department: http://www.youtube.com/watch?v=DJV5PSpYPL0#t=183
