We have been learning about simple machines and how they make life easier.
Just for fun we have built Rube-Goldberg machines.
Rube-Goldberg machines are the opposite of simple machines.
They are complicated machines that do a simple task.
My rube-Goldberg machine is made up of levers and 2 inclined plane if you want to know how it works you let the marbel go down the inclined plane and the marbel will go in the second inclined plane and the marble will hit some dominos and go in the cup.
Area of a rectangles
We had to draw as many rectangles as we could think that had an
area of 12 square unit.I drew 4 rectangles 1 is 1 x 1,2 x 2,3 x 3,
4 x 4 .Then we had to answer a question -could we draw a square that had that area ?The answer is no because the numbers have to be the same for it be a square for example 4×4=16would make a square.
