It concentrates on the same issues as the Teacher's Book: ozone layer depletion, protection and the health risks of strong ultraviolet radiation. Teacher's will set the scene for the students. They are journalists who have to complete their article with a deadline or lose their jobs. Before they write their article, they will need the results of all their missions from their notebooks.
