In our stem class we have been studying simple machines. we had to go to our homes and find an example of each simple machine.

I am holding an axe. A axe is a wedge. It helps to make things easier to cut.

I am holding a baseball bat. A basebal bat is a lever. The bat helps you to hit the baseball.

I am pointing at stairs. Stairs are an incline plane. an inclined pane helps to get things from one level to the next.

I am holding a screw. the screw is a screw. Screws help to hold things together.

I am pointing at a solar cover wheel. the wheel is part of a wheel& axle. It helps to put things on or of or can make things easier to move.

I am pointing at a pulley system. it is a pulley. Pulleys help to raise or lower things.
