Rollerball Champions (Forces Homework Task)
We had a lot of great rollerball machines built. There were lots of creative ideas – ramps, sticky substances, fluids, narrow tubes and more. Quite a lot of people managed to get the ball to take close to the 20 second goal.
LEON was the winner of the contest. His ball took 20.1 s to reach the bottom. Click on this link to see how he did it.
There were several other fantastic constructions. Click here to see them.
