As a group we are going to be developing a 'Green Revolution' jigsaw. To do this the group will be divided into four teams and will complete the following tasks:

  1. Each team has 20 minutes to research one of the four elements of the Green Revolution 
      • agricultural systems
      • scientific and technological innovations
      • the expansion of the area under agriculture 
      • growth of agribusiness
  2. Each team chooses one of their peers to be the 'expert'. The 'expert' will stay static (seated) and the rest of the team will rotate around the different groups. The expert from each team will inform the joining group about their section of the Green Revolution. The moving team will write down notes.
  3. The rotation will continue until the original members of each team rejoin. Those students who have rotated then inform the expert about the other aspects of the Green Revolution.
