I love lessons that incorporate the arts, they're so engaging and address a more diverse set of learners. Your class will investigate the reasons fish from the coal reef have adapted such colorful fins. They design a fish that uses color to either signal something or as camouflage, then they take a trip to the California Academy of Sciences to see real coral fish in action. Upon returning to class, they discuss their observations and then write a clever haiku to accompany their images of fishy adaptation. Note: If you don't live in San Francisco, you can always take a trip to a local tropical fish store to view fish that would live on a coral reef.
