We started making our marble runs.
This involves working together and testing our designs as we go.
The idea is to keep the marble moving but also to try and slow it down so it
takes as long as possible to reach the end of the marble run.
Gravity is trying to pull the marble towards the centre of the Earth.
The cardboard platforms are creating an upwards push against gravity.
The marble is gathering momentum which shows itself as
movement/speed without any extra help (such as a push).
There is friction pulling on the marble and slowing it down as the
surface of the marble moves along the surface of the cardboard.
