Simple Machines by Joe and Jackson

         Simple machines  make work faster and  easier.  Here are some examples of  simple  machines: pulleys, wedges,screws,and gears.  Here are some examples of  pulleys: flagpole,and conveyor belt.  Pulleys help you lift objects when it is too heavy.     A wedge is a simple machine.  Here are some examples of wedges: ax, teeth, knife, and nail.  A wedge is an object that split things in half.  Simple machines are magnificent.
