What makes a good science teacher?

For those of you who may be unfamiliar, over at Scienceblogs.com they have a weekly feature: Ask a Scienceblogger. Previous questions have included topics as diverse as “brain drain” and the future of the human race (you can view the archives here). This week’s question is one that I thought might interest folks here, as I and others regularly write about science education (and how to improve it). The question is (as noted in the title), “What makes a good science teacher?” I have my thoughts up over at Aetiology, and you can find other musings posted at this link for the next week.
