We've been learning about force and motion in science. A force is a push or pull applied to an object to put it in motion. For our first investigation, pairs completed an obstacle course. Each pair used a broom to push or pull a bowling ball through a course while trying to get the fastest time. The students agreed that it was harder than it looked. They did great!
Our second investigation was all about friction. Friction happens when there is resistance from a surface or object which slows down the object in motion. We tested out six different ramps. First we made predictions about which ramp surface would create the most friction with a small moving toy car and which surface would create the least amount of friction. Then we tested them. We measured the distance the car traveled after it left the ramp.
