The Design and Technology

The DT builds on previous skills of making a wheeled chassis and adding the rocket body and there is plenty of scope for thinking about the design in terms of strength and fitness for purpose. Many of our cars were tested to destruction and rebuilt several times!

Construct a chassis with axles and wheels to support a 2 litre drinks bottle.
It must roll freely and be of a sturdy construction that will allow the rocket car to survive being tested several times. You may wish to consider aerodynamics.

Construction resources

• I cm squared softwood
• 4 Wooden pegs for axle holders
• Card triangles
• 4 Wheels
• Dowel to fit wheels to form axles
• PVC tubing to slide over dowel
• A water proof wood glue (available in DIY stores)
• 2 large cable ties
• A 2 litre drinks bottle

These are suggested materials, your teams may have better ideas for constructing the rolling chassis.
