What the Activity is for

This is a discussion activity which focuses on the rapid expansion in the range of electrical devices in the home within the last 30–40 years.

What to Prepare

What Happens During this Activity

The pupils might be asked, for homework, to collect some information about the electrical appliances that older neighbours or relatives had in their homes some 30–40 years ago. They can report back their findings in a class discussion which also draws upon the data shown here.
