Design Technology

Your challenge this week is to design and make a rubber band car!

The documents below will give you ideas and instructions for how to build your rubber band car. Once you have your basic car, decorate it to make it your own. 

Draw a labelled diagram of your car. 


With any engineering project, testing is essential. You’re unlikely to get it right first time, and there are always adjustments you can make to improve your cars performance.


The main aim is to get your vehicle to travel as far as possible with one ‘charge’ of the elastic band.

Try adjusting some variables (weight, friction of the surface, friction of the wheels, turns of the rubber band) until your car is at peak performance.


Remember: only change one variable at a time or you won’t know which of the changes has been effective.
