The first grade class learned about simple machines. There are six types of simple machines. They are levers, pulleys, wheel and axle, inclined plane, wedge, and screw. They learned about each of these during their Science unit by doing fun investigations in class and each student made their own simple machine log book.
They invented their own machine and then created those machines using various scraps of recycled materials. During their presentation, they had to explain how this invention would work and why it was helpful. Way to go first grade!
