We recently finished up our science unit on Force and Motion. We started our unit by learning that a force is needed to make an object move, change speed, or change direction. We explored this concept through an interesting obstacle course. The students had to push or pull a bowling ball with a broom through our course and keep it in the boundaries. The students found that the direction they pushed or pulled with the broom was the direction the ball went. The students found that it wasn't as easy as it looked!
Another concept that we explored was friction. We questioned whether the type of surface on each ramp would affect how quickly or slowly a small car would go down a ramp. We measured this by how far the car traveled from the ramp. In our investigation, the plain wooden ramp had the least amount of friction and the rubber material on another ramp provided the most amount of friction.
