See a. above. If children are to become aware of how the world is being designed by people, we need to make them more aware and sensitive about how things are becoming worse or better in our immediate surroundings. This is part of teaching aesthetics. We have laws against noise pollution, air pollution, and water pollution. Should their be more laws against polluting our viewscapes.
Everyday experiences can be an important as a source of topics from which to work.
Also, add some ideas about how this lesson can make us more aware of our environments. Include some relevant questions to ask the class. For example, when I think about juxtaposition of visual themes in surrealism, and apply this to the way campus buildings have been modified over the years, I become more aware of the impact of architectural space and design in my environment. Every school and neighborhood has some relatively ugly and some relatively beautiful environments. One of our goals is to help children develop sensitivity and aesthetic criteria by which to become more responsible citizens.
