We have been learning about simple machines and how that 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 machine is made up of two simple machines Pulley and an Inclined plane , lever. Here it is in action!
Reflection-Area of rectangles
We had to draw as many rectangles as we could think of that had on area of 12 square unit. I drew 5 square. Then we had to answer a question-could we draw a square that had that area ?
The answer is no because the factors are not equal. If the factors are equal it would be a square like 4×4=16.
