Rube Goldberg machines make simple machines harder by adding more steps. For my Rube Goldberg machine, my topic was "Throwing Garbage Into A Garbage Can". The first step is that I step on a dog’s tail. The science concept is kinetic energy. The second step is that a dog runs because it’s surprised. The science concept is that an object in motion will stay in motion unless another force acts upon it. The third step is that a dog runs into a string. The science concept is pull. The fourth step is that the string pulls down a knife that’s tied to the string. The science concept is pull. The fifth step is that the knife cuts a string that’s holding an arrow. The science concepts are push and wedge. The sixth step is that the arrow bumps into a watering can. The science concept is that an object in motion will stay in motion unless another force acts upon it. The seventh step is that the tilted watering can pours water onto a water wheel. The science concept is gravity. The eighth step is that the weight of the water makes the pulley move. The science concepts are potential energy and pulley. The ninth step is that the other cups that don’t have water in them flip a lever. The science concepts are push and lever. The tenth step is that is that a ball rolls down the lever. The science concept is gravity. The last and final step is that the ball rolls down to hit a lever bouncing the garbage on the other side off and land in a garbage can. AND the last and final science concepts are that an object in motion will stay in motion unless another force acts upon it and lever. So, how was the paragraph?
