The school day starts at 8:05 but I usually come in an hour early to set labs up or clean from the previous day. I can also enjoy a coffee and check science news to share before the halls are flooded by chatty teenagers. We have 9-40 minute periods. I teach 5 periods in addition to a study hall, free period, lunch, and lunch duty. Every other day a class has a double period lab block. The day ends at 2:45. We have alternating “A” and “B” days which allow for changes in the schedule. Occasionally we have an assembly or special event that breaks up a typical week.
