Sure! Here are the answers to your questions:

  1. What are compound machines? How do they make work easier?
    Compound machines are made of two or more simple machines. They help us do work more easily by combining their powers, like making lifting something heavy easier.

  2. How does a zipper work?
    A zipper has teeth that catch onto each other when you pull the slider. When you pull it up or down, it opens or closes fabric.

  3. Which simple machines make up a can opener?
    A can opener uses a lever and a wheel. The lever helps cut the lid, while the wheel helps turn and grip the can.

  4. Which simple machines make up a bike?
    A bike has wheels, levers (like the pedals), gears, and sometimes pulleys. They work together to help it move smoothly.

  5. Which simple machines make up a hedge trimmer?
    A hedge trimmer has a blade (that acts like a wedge) and a motor (like a pulley). The blade cuts branches while the motor powers it.

  6. How do wheelbarrows work?
    Wheelbarrows use a wheel and a lever. The wheel makes it easy to roll, and the lever helps lift the load when you tilt it.
