Year 4: Mechanical Systems - Sling Shot Cars
Mechanical Systems – Levers and Linkages
- I know that all moving things have kinetic energy.
- I can consider the effect that air resistance will have on my product.
- I can draw a net to create a clear structure, cutting and assembling with increasing accuracy.
Challenge: I can consider the effect of shape and the accuracy of workmanship on performance.
Year 5: Mechanisms - CAM Moving Toys
Mechanical Systems – Pulleys and gears
- I know that an automata is a hand-powered mechanical toy that uses cams, followers and axels to create motion.
I can explore the relationship between cam profiles and follower movement, to inform design decisions.
- I can explain what cross sectional diagrams are and why they are useful.
I can explore how to reinforce a structure.
I can identify points of weakness, reinforcing them when necessary.
