We have been learning about simple machines and how they make work easier. Just for fun we have built a Rube-Goldberg machines. Rube Goldberg are the opposite of simple machines.
They are complicated machines that does a simple task. Our Rube Goldberg machine is made of 3 simple machines it is made of ramp,lever,and a inclined plane.Watch our machines that works!
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 that had that had that area?
The answer is no because The factors are not equal and there is no matching sum that will make a sum that will make a square so 3×4 doesn’t make a square but 4×4 make a square.
