This is an interdisciplinary, 5E unit that begins with students becoming animal detectives to explore the school habitat, moves on to students watching wolf families on a webcam, and ends with students forming groups to become "Animal Detectives." The students investigate a focus animal, with each group having a different animal in their "mission folder". The key questions in the unit are: 'What characteristics does the animal have to help them survive in this environment?', 'What would they need to survive?', 'How might these characteristics help them survive?', 'What traits did the offspring inherit from the parents?', and 'How do the traits vary among the offspring?'. The unit authors suggest that this activity should take ten class periods. A unit overview can be found here.
