CASE 3
Ann K. teaches in a rural district located in a heavily forested county of the Pacific Northwest. She needs to teach a unit entitled, "Levers and Pulleys." After giving the problem some thought, she thinks it might be acceptable to focus the unit on the question "How can I lift furniture into my tree house?" She thinks the question has some merit, but she asks you for a second opinion.
