Outcomes

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

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)

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.

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
Air resistance force/drag– ball bearing dropping through oil, model of dolphin, dropping ball and feather, parachute person
Normal Force- block and strong card
Thrust - balloon (long ones and fat ones), straws, 2 lines of string to go from the front of the lab to the back of the lab close to the ceiling

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.
