Pupils are invited to label photographs of levers so that they can get better at finding the lines of action of the forces...

Classroom Activity 11-14

Here pupils get their hands on devices based on levers, and get to describe and analyse them as such. You might choose to do...

Classroom Activity 11-14

You can use this model to bring out and keep to the fore the central qualitative relationships between the forces, lengths and...

Classroom Activity 11-14

The purpose of this activity is to engage the pupils in making calculations based on levers. These can be hard to do...

Classroom Activity 11-14

Here, pupils shift fluid from one cylinder to another, making predictions about the forces generated from the distances moved...

Classroom Activity 11-14

To allow some practical experience with using a pair of linked cylinders as levers. To reinforce the idea that the forces...

Classroom Activity 11-14

Many levers work as force-multipliers. In this case a small force (or effort) acting on the lever moves a large distance to...
