Galvanisation is the process of zinc-plating other metals to protect them from corrosion. Metal sculptures are shown being cleaned in an acid bath then dipped in a bath of molten zinc. This forms a zinc coating which will protect the metal inside for hundreds of years.

You could compare the use of galvanisation with other forms of corrosion prevention. Students could investigate different methods and list their pros and cons before carrying out a card sort, matching different methods to specific applications. Relate galvanisation to the electrochemical series and electrolysis demonstrations carried out in the classroom.
