Resources Required
- Electrical Force - balloons for electrostatics, rice in a plastic bottle charging polythene rods and using watch glass show repulsion
- Frictional- slope with different objects (car, glass block and wooden block) where they change and measure the angle + hovercraft
- Magnetic - 2x bar magnets, iron filing in a boiling tube, horse shoe magnets attached to two vehicles with ability to reverse them.
- Upthrust - pieces of wood in water, different sized paper boat with paper clips to add, transparent water bath
- Strain/Spring force- spring and masses, rubber bands, squashy ball
- Gravitational – different masses on a Newton Scale, planetry model
- Applied Force – Push or Pull and Thrust – pulling brick with Newton meter, stones on a tray and water jug, stream of peas to drop onto a balance, balloon with a small tube and placed over a large retort stand + balloon pump
- Air resistance force/drag– ball bearing dropping through oil, model of dolphin, dropping ball and feather
- Tension Force- ball and string, tyrolean traverse with barbie attached
- Normal Force- block and strong card

Skills Addressed
Safety/Hazards
- A tank with water in it will be heavy and so is only to be moved by the technician; please refer to the Manual handling section of the Laboratory Lessons Health and Safety Risk Assessment
- When using springs, goggles must be worn
- The main risk is from the vacuum pump and apparatus. The specific risk assessment must be read before using the apparatus.
- General Laboratory Health and Safety Risk Assessment
Notes
- None
