1. Harrisons GSTEM Powerpoint

2. think- what does the design have to do.
Drive
Move on ground under water or through air
Move on different surfaces flat bumpy snowy wet
Must be self propelled
Must not use batteries

3. research- what can you find out about the problem?
I looked on YouTube for self propelled vehicles
Looked for different types of car.
Googled pictures

4. imagine- come up with ideas & possible solutions
Could be balloon powered
Wind powered
Could use an elastic band

5. plan- select a design that seems the best solution
I have chosen a Balloon powered car
I think it will go further than a elastic band or wind powered car
I think it will look better than the other cars

6. plan- select a design that seems the best solution

7. plan- select a design that seems the best solution

8. plan- select a design that seems the best solution
I wrote a shopping list of the things I need for my model.
Bottle
Balloon
Crayon case
Cotton Reels
Wood [sticks]

9. create- make a model or prototype of your design.
We used a saw to cut the wood.
We used a hot metal spike to melt holes in the bottle.
We used tape to stick on the crayon with the balloon on.
We used drawing pins to keep the wheels on.

10. Test and evaluate

11. Communicate- tell people about it.
My mum was on holiday so we videoed it and showed her.

12. Improve- redesign to make it better
