We have been learning about simple machines and they make work easier.
Just for fun we have built rube-Goldberg machines. Rube Goldberg machines are the opposite of a simple machine.they are complicated machines that do a simple task. My Rube Goldberg is made of 2 simple machines pulley lever and inclined plane here it is in action
What did we learn:We had to draw as many rectangles as we could think of that had an area of 12 square unit. I drew 3.Then we had to answer a question-could we draw a square had that area? The answer is no because you can’t make a square if the matching sum doesn’t have 2 equal factors. An example of a square would be 3×3=9.
