Yr 4 Ancient Greek week. Water Wheel design, build and Test.
We designed our water wheels and tested them using 1 Ltr of water to see how many times the water wheel would turn. We collected data and did diagrams of the water wheels.
The invaders were approching our city, so we prepared against their attack by building catapults. We tested and tried to improve our designs. We then took the catapults out side and tested them, we recorded how far the Lego people flew!
