Dr. George came in this afternoon to talk to us about the S-K greenhouse project. We focused on heat loss today, which will be a major concern as we try to grow vegetables this winter. We tackled some heady concepts, in a very challenging piece of text. For some students, this was their first exposure to the concept of variables in a mathematic expression. (And I'm fairly certain that it was the first time that any of us had heard the term 'heat transmission coefficient'.)
Be sure to check out Dr. George's blog, which is full of information about the greenhouse, as well as other cool projects that he has cooking.
