As 'Inventors' the children in Pearl Class have investigated what makes objects move.

They asked questions:
How can you make an object move?
Can you explain friction?
Predict what will happen if the pull force is greater in one direction than the other?

Using the Lego bricks the children built a Pull-robot that can pull an object over a short distance. The children then created an algorithm to program the Pull-robot to pull an object over a short distance.

The children tested to see how much the Pull-robot could pull before it stopped. The children themselves asked what would happen if the type and size of the tyres changed.
