Have the students make a poster to raise awareness about the issue of sewage. Split them into groups of 2 or 3 and have them pick three pieces of information that really stood out for them and that they felt other people should be aware of.
Students will discuss the process of cleaning polluted water in terms of filtration. Students will also look more closely at other types of water clean up such as air stripping, bioremediation, and phytoremediation.
