Today we did another activity to expore force and friction. We had a tug of war. First we went into the hall, where the surface is smooth. We tried having a tug of war in shoes, socks and barefeet. We found the tug of war in sock extremely difficult as there was hardly any friction and we were sliding all over the place. We felt that there was more friction when we had barfeet.
Next we went outside on the grass and did the same. Once again socks was the hardest and barfeet the best.
So we know that when we have Race Day with our CO2 cars the hall will be the best place. We want to reduce friction so our cars go FAST!
