Now that you have some information and personal experience around 24 hour time, have a discussion or debate with family, friends or classmates. Here's how: 1. Divide into two teams, one side supporting the use of 12 hour time and the other side supporting the use of 24 hour time. 2. Each team makes a list of arguments for their side and completes a written essay supporting their side. 3. The two teams then have an oral debate about which ways is more useful.
