The children work in groups of 3 to design and build a catapult. We learn about strong structures and catapult design. 

We test our catapults and improve our designs. 

 In this session we include the following:

Maths: We measure distance and collect data.

Statistics: Record data in a table and use the collected data.

Technical Knowledge: Apply understanding of how to strengthen and reinforce more complex structures. Understand and use mechanical systems.

Science: Predicting outcomes. Fair tests.
