Welcome to the Ozone Layer Education for Secondary Schools Teacher’s Book. It is a simple introduction to ozone issues for young people aged 13-16 years. Think of it as a Mini-Montreal Protocol guide. The education pack aims to raise awareness and encourage the active participation of young people in the debate on ozone depletion, its potential effects on them, the place in which they live and the planet. It also offers them a chance to design their own projects for taking action. These materials build upon ideas and activities in our OzonAction Education Pack for Primary Schools and other Ozzy Ozone materials.
