The Cell Project--PBL Applied

The Cell Project illustrates one use of problem-based learning that sounds intriguing. One class of eleventh graders at High Tech High have been given the challenge to teach seventh graders all that they've just learned about cell biology. As you watch this, what questions do you have about it? What works from what you can see? How did they decide to go about teaching younger learners? What do you think of their approach? How would you go about setting up a situation like this?
