Speed Trials challenge
The British Grand Prix starts tomorrow. In the last practice lap, the world champions car spins off and is wrecked. Can you help, by building a brand new Grand Prix racing car for him?
Levels of difficulty:
Level 1 - Make a simple racing car Level 2 - As level 1, with a spring motor Level 3 - As level 2, that will travel at least 3 metres
Equipment: KNEX set with small wheels, plus spring motor for level 2 .
Approach: What is the best shape for a racing car? Where will the wheels go? Where does the driver sit? For level 2, how can you make the spring motor drive the wheels? How will the motor fasten on to the body? For level 3, test your car. Will it travel 3 metres? If not, can you improve your car to make it travel further? What would happen if you tested it on a different surface?
