  2. What is a machine? A machine is a piece or many pieces put together to get work done. Work in Science refers to any push or pull, in order to move an object.

  3. Lever A lever is a long bar with a support. A lever contains a fulcrum, which is the support part of the lever machine.

  4. Wheel and Axle A wheel and axle is a special type of lever that moves or turns an object. The axle is the rod that goes through the center of the wheel.

  5. Pulley A pulley is a wheel with a rope, wire, or chain around it. A pulley changes the direction of a force.
