The document discusses strategies for teaching ecology in high school classrooms, including the use of reading and graphic organizers. It recommends having students read various materials like books, magazine articles, and web synopses to learn about ecology concepts. Students should make concept maps, Venn diagrams, or compare/contrast matrices while reading to help organize information. Graphic organizers like "color-your-own" diagrams can help students understand the different levels of ecology from the biosphere down to individuals. Writing activities can also reinforce lessons, such as having students identify a local ecology issue and incorporate key terms, or writing persuasive letters from different stakeholder perspectives.
