Today we reviewed everything we have learned thus far. Then we continued to add new learnings and discoveries. We learned that friction is a force that is created whenever two surfaces move or try to move across each other. Friction slows down or stops an object. The students then became engineers! They worked in partnerships to problem solve and design. Their challenge was: design a ramp that slows a ball down. The ball was only allowed to be pushed by gravity (we were not allowed to give the ball an extra push or blow on it, for example). Students first brainstormed and then drew their designs on paper. As students started building, it was amazing to watch! They continually had to problem-solve and re-think their work. They also had to figure out how to compromise and work as a team. I am so proud of how well they worked as scientists!
