A FUN-filled STEM Challenge at King’s Ely Acremont saw Year 2 pupils building catapults and putting them to the test!
The children spent the afternoon firing and recording the distance that the dried pea ‘cannonballs’ covered in centimetres. They discovered that the construction of their catapults and the amount of force applied were variable factors, while the starting position and the pea used were the constants.
They recorded their measurements between 60cm and 400cm!
