Screw




            A screw is a simple machine that makes work easier or faster. It looks like an inclined plane wrapped around a pole. Screws put objects together and also lift objects. Some examples are jar lids, vise, and bolt. The people who use screws are construction workers and venders. If you like to ask questions ask now

    Have you ever used a screw before?

    I like how you included the lids of jars…most people don’t think of these as screws.
