Outcomes

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

• Applied Force (push/pull)
• Frictional Forces
• Normal Force (Reaction)
• Gravitational Force (Weight/gravitational pull)

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

Discuss how we represent forces. Lead the discussion to the idea of a free-body diagram. Pupils need to know that the direction of the arros is important as is the size. Also they should know that the diagram shows the forces acting on one object.

Main Body of Lesson

• The force circus has now been split in three. 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 4 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.

Additional Information

Resources Required

• Frictional- slope with different objects (car, glass block and wooden block) where they change and measure the angle + hovercraft
• Gravitational – different masses on a Newton Scale, planetry model
• Applied Force – Push or Pull and Thrust – pulling brick with Newton meter, sand to pour onto a balance
• Normal Force- block and strong card
