Outcomes

Pupils should be able to give examples for, label and name a range of forces including

  • Upthrust
  • Tension Force
  • Spring Force
  • Electrical Force (electrostatic attraction/repulsion)
  • Magnetic 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

  • The force circus has now been split in half. To get through the circus I suggest talking through each station with the entire group having different pupils undertaking the experiment as you go. There is also a powerpoint with some simple definitions of the 6 forces covered in this lesson.
  • Laminated copies are provided with the circus- copy in science shared
  • You may be asked to have types of forces lesson 2 prior to lesson 1 so that kit can be easily shared.

Plenary

  • Set up a balloon which is electrostatically charged, on the ceiling, attach a string with a paperclip at the end. With a strong magnet on a retort stand, arrange it so that it is attacting the paperclip in the horizontal direction. The paperclip could have a wooden block attached to it which is floating in a beaker of water find set up here
  • Have students draw and label the forces acting on the balloon and paperclip. Ask them to consider the size, direction and type of force

Additional Information

Resources Required

  • Electrical Force - balloons for electrostatics, rice in a plastic bottle charging polythene rods and using watch glass show repulsion
  • Lift - wing
  • Magnetic - 2x bar magnets, iron filing in a boiling tube, horse shoe magnets attached to two vehicles with ability to reverse them, magic floating paperclip
  • Upthrust - pieces of wood in water, different sized paper boat with paper clips to add, transparent water bath
  • Spring force- spring and masses, rubber bands, squashy ball
