We have been learning about simple machines and how they make life easier. Just for fun we built Rube- Goldberg machines. Rube – Goldberg machines are the opposite of a simple machine. The are complicated machine that do a simple task. My rube -Goldberg machine machine,is made up made up of 2 simple machine called a lever and a wheel and axle. Our machine lifts the car in the air. It doesn’t work yet but we’ll keep trying!
