Today we continued with our D.T. project.
W.A.L.T. To write a procedure to follow to make our electric car.
W.I.L.F. Clear, step by step instructions.
1. Collect wood and equipment and cut the wood for the chassis.
2. Cut the balsa wood for the base for the motor and the battery.
3. Cut the wood for axles and leave aside.
4.Put a rubber band around each cotton reel and put the other end of the rubber bands around the motor.
5. Glue the motor holder and battery holder to the balsa wood.
6.Glue the wood for the chassis together and stick to the balsa wood.
7. Put the battery in the battery holder.
8. Put the motor in the motor holder.
9. Connect the battery to the motor with wires and crocodile clips.
10. Put the axles halfinto the chassis and put on cotton reels. Finish putting the axles in and glue on the wheels.
11. Decorate, and glue on the shells.
12. Test, and mark out of 50.

My Design Specification by Juliet
EQUIPMENT - motor, crocodile clips, battery, ruler, elastic band, battery holder, A4 piece of card, pencil, bench hook, glue gun, balsa wood, cotton reel, scrap wood, saw, wheels, axles.
SIZE - My car will be 15cm x 12cm.
DESIGN - Appearance -5 teachers will each judge your model out of 10, to make a final score out of 50.
TRAVEL - To be successful my vehicle must travel at least 3m.
TIME - The time we have to build, plan and have our cars judged is 3 weeks.
COST - Prices are:- wood 30p, motor 50p, cotton reel 20p, wheel 10p, battery 20p, elastic band 5p, battery holder 10p, scrapwood free, A4 card 50p.
HOW MY DESIGN WORKS
The battery generates electricity which the crocodile clips conduct, leading to the motor. The motor causes the cotton reel to spin, which makes the elastic band and the cotton reel spin. These are connected to the wheels. This makes the wheels spin. This will make the car move.
The SKIL
LS we are using in this project are:-
MATHS SKILLS - measuring chassis, axles and distances that the axles should be inserted.
COMMUNICATION SKILLS - discussing an agreed design and procedure to follow.
I.C.T. SKILLS - eventually using 'CAD it CAM it', to design the shell.
THINKING SKILLS - When building, there will be a large amount of making, re-evaluating and thinking of ways to make the car actually move.
