Contents
Outcomes
- Pupils should be able to give examples for, label and name a range of forces including Frictional Forces, Gravitational Force (Weight/gravitational pull), Tension Force, Electrical Force (elecrtostatic attraction/repulsion), Normal Force (Reaction), Magnetic Force, Air Resistance Force (drag), Applied Force (push/pull) and Spring Force.
Specification References
- 1.7 Express a force as a push or a pull of one body on another
- 1.8 Identify various types of force (e.g. gravitational, electrostatic etc)
Starter
Main Body of Lesson
Plenary
- Discuss the stations as a class. This is an opportunity to use the hand held white boards to test their understanding.
Homework
- file too large to upload
Additional Information
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
