The Great Book Race is about to start. Theyre under starters orders theyre away! Can you make a vehicle for the Great Book race, that can carry a book right across the room?
Levels of difficulty:
Level 1 - Make a vehicle that will carry a paperback book Level 2 - As level 1, with a motor Level 3 - As level 2, that will carry the book right across a room
Equipment: KNEX set, plus a paperback book. Also, for level 2, a K'NEX battery motor.
Approach: Carrying a book along isnt quite as easy as it sounds! How can you build a vehicle strong enough to carry the weight of the book? How will you stop the book falling off as the vehicle goes along? For level 2, how can you attach a motor to your vehicle? For level 3, does your vehicle steer in a straight line? It will need to if you are going to complete the Great Book Race!
A project to set a specific practical design and technology task, in which the design of the vehicle required is entirely up to the child.
Possible solution: See photo.
Before starting: Mark the start and finish of a test track across the floor.
Conclusion: Firstly, compare the different designs which have successfully completed the course, and list the different ways that the objective has been used. Then predict what will happen to each of the models as the number of books is increased, and carry out tests to check those predictions .
