Exemplars (from the NaCCA curriculum)

- Find out from learners what they understand by clean air and review things that pollute air (make air unclean) such as smoke from factories, car exhausts, bush burning and dust from construction sites and untarred roads.
- Lead discussions to come out with the do's and don'ts that will make or keep air clean in our homes and surrounding environment (planting of trees and grass and avoiding frequent and uncontrolled burning).
- Learners are assigned to design a concept map on the causes, prevention and control of air pollution.
- Learners draw and use a Future's Wheel to trace the effects of water pollution on the environment.
