The Marble Run Challenge
It took us a long time to come to our decision! First and most importantly, the models had to keep the marble moving for at least 3 seconds (Key Stage 1) or at least 5 seconds (Key Stage 2).
Those models which did were then judged against the following three criteria :
- Was the marble run sturdy and well-made? Did it work every time?
- Was the marble run inventive and creative? We were especially impressed with models that had more than one mechanism.
- Did the model include a scientific explanation? This was particular important for Upper Key Stage 2 entries.
The winners of the Marble Run Challenge are as follows :
