Zinc is a hard, brittle metal. It is most commonly used mixed with other metals to make alloys like brass, and as a coating on other metals to stop them rusting. Zinc stops other metals rusting because when it is attached to another metal it will rust before that other metal does. The other metal will then start to rust when all the zinc is gone.
Metal that is coated with zinc is called galvanized. If you look closely at galvanised metal you can see the zinc crystals.
A zip is a device that keeps your clothes closed. It is made from two strips of tiny teeth and a slider that meshes the teeth together when you zip it up and unmeshes them when you unzip it.
Zips are found on many, many kinds of clothing. Before zippers were so popular, people used buttons to keep clothes closed.
