On Monday morning we were given a challenge – build the fastest K-Nex Car! We spent the morning building cars in groups and then we had to find out the fastest. We had to think about how to work out the speed. We eventually worked out that we needed to know the distance something has travelled and how long it took to go that distance. We could then work out the speed. Speed = distance/time.
We watched a video of how the police use this to work out if cars are speeding. You can watch the video here.
