Why Lesson Planet?
Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a wetland plant or animal to have clean water. Overall, this is a creative ecology lesson, but the refraction activity is unrelated. Consider skipping that activity if you want to include this when exploring human impact on the environment with your emerging ecologists.
