Learn how wheels and axles use friction to move objects easily and how big tyres compare to small tyres. Find out how an inclined plane can be used for lifting heavy objects and how another form of inclined plane, the wedge, is used in every day applications. Build 14 working models such as a launching platform, a door with knob, a well, an airport staircase, an experimental ramp and a splitting wedge. You can find easy-to-follow building instructions for all models in the booklet included. The booklet provides detailed explanations of the different scientific principles applied and incorporates innovative experimental activities for hands-on learning. A Quiz section is also available to challenge your newly acquired knowledge!Build a car with reverse turning wheels

Follow the instructions to build this model of a field tractor and learn how different sizes of wheels produce different results. Learn how the size of the axle also affects the mechanical advantage of the machine.

Build a car that turns

Construct this model and find out in what ways the axle and the wheel connect for different purposes. Learn how levers can be used to create a steering wheel, even though this particular one is turning in the wrong direction!

Build an airport staircase

Construct a model of an airport staircase that comes on wheels and find out why it is easier to climb an inclined ladder instead of moving straight up. Learn about the mechanical advantage that is gained when an inclined plane is used.

Build a car with crane

This unique model of a car with crane will help you understand the principles of inclined planes and how they help lift heavy loads. Learn how the inclination of the plane affects the amount of effort applied and what inclination is.
