Photocopy the text from the 'good' and 'poor' sides of the poster on separate sheets. Although the poster definitely targets particular catchment issues, the task is open-ended and students may incorporate a whole range of management strategies that have not been included in the 'good management' side of the poster. These could include providing sediment control on a building site, for instance. They can then discuss their ideas with the class. Using the text from the 'poor' side of the poster, students add any issues they may have missed.
Students then compare the 'good' and 'poor' catchment management diagrams.
Many applications of science are shown in the activities on the two sides of the poster. Students describe how community attitudes might influence decisions that are made about the applications of science. Students list all the people in the community who would be involved in creating a 'good' catchment. Using the text from the 'good catchment' side of the poster, students can add to their poster or to their list of community stakeholders. Students write two paragraphs explaining how these community members could coordinate their catchment management strategies.
