(1) Find some small application of elementary physics, perhaps in anatomy, energy production or consumption, public health, medicine, etc. It should draw upon only topics we have covered (rather a restrictive requirement so far). You should point out how physics applies, and how it clarifies something about this topic in some way, using only the simple kinds of arguments we are learning to make. This is not an easy thing to do! In particular, I hope this means you won't just find something on the web and appropriate it wholesale, because nothing on the web is this stripped-down. It should just be one essential physical idea, clean and clear, and perhaps very approximate, or even speculative -- that would be fine. Write up your idea in a clear exposition of maybe one page. I'll maybe make suggestions when I see it, and we will refine it. Aim to make it something you can present as a 5 minute topic for the class as a whole. A good presentation should be worth an increment in grade.
(2) Make a comment or raise a question in class that takes us in a new and productive direction. When you think you have done this, write me an email message repeating the remark, and say why you think it was productive. If I agree, I'll file it in my extra credit folder. Two of these should be worth an increment in grade.
