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 (electrostatic attraction/repulsion), Normal Force (Reaction), Magnetic Force, Air Resistance Force (drag), Applied Force (push/pull) and Spring Force.

1.23 recall and use the relationship between the moment of a force and its distance from the pivot: moment = force x perpendicular distance from the pivot
1.24 recall that the weight of a body acts through its centre of gravity

File too large to upload - laminated copies are provided with the circus- copy in science

Set up a balloon which is electrostatically charged, on the ceiling, attach a string with a

Electrical Force - balloons for electrostatics, rice in a plastic bottle charging polythene rods and using watch glass show repulsion

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.
