We have been learning about simple machines and how 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 simple task. My Rube Goldberg machine is made up of pulley,levers,incline plane. Here is in action.
We had to draw as many rectangle as we could think of that had an area of 12 square unit.I drew six rectangles but some of them are just flip over.Then we had to answer a question.Could we draw a square that had that area?The answer was no because square area must be the same number times Together example: 2 times 2 is the square areas.
