Science Experiments

This week we did some Science Engineering projects. We had to plan, design and create a container that would carry a pingpong ball along a zipline between two chairs. The pingpong ball had to take 5 seconds exactly to move between the chairs. We have been learning about friction so we had to use the principles of friction to help us make the ball travel in exactly five seconds. It was tricky but we had fun testing and improving our ziplines.
