Quiz on Tuesday 12/10
The 6th graders have begun their chapter on energy and its different forms. They participated in a fun activity to reinforce their lesson on potential and kinetic energy and what they learned so far (that the greater the potential energy of an object, the greater the kinetic energy). Students were to build ramps that a car can drive down, where they would hopefully crash into a block and knock it over. First, students built a ramp with low potential energy. When the car went down this ramp, it did not go very quickly and barely moved the block. Students then built ramps with high potential energy. Their cars went down this ramp faster and moved the block further, but it did not knock it over. We finally knocked the block over when a tennis ball was sent down the ramp with high potential energy. Students concluded that the ball knocked the block over because it had greater mass.
