Grade 5 had so much fun studying simple machine in Science class today. With the help of principal Woodmansee, a maul, a wedge and a mallet, we learned how to split wood by using our hands and some simple tools. A good tool extends the power of your hand. Tools are all around us. A fork to whip in egg, a needle to sew a hole, and a hoe to mix sand and cement are all pretty amazing tools.
Today we focused on splitting wood. We learned about effort and put-put the effort in arm resistance, the force of splitting wood. We determined that it’s easier to split wood with a maul instead of a mallet and a wedge. This is because of the better leverage because of the longer leverage effort arm, heavier head of this tool. “This made the lesson so much easier to understand than reading it out of a book.”-One student said. “Totally one of the best Science class yet!”-Another student stated.
