I want to thank Professor James for letting me have a few minutes of class to tell you about our field trip tomorrow. We'll be leaving by bus at eight in the morning and return at about five. Please bring your lunch.
As you know, this trip is a requirement of the course. You're all expected to take part and then to write up a report in your laboratory notebook.
I've put together a handout to guide you. Please pick it up after class and read it tonight. In it I discussed the members of the pine tree family found here. As you have learned, the pine tree family is made up of pines, larches, spruces and so on. We'll be looking at examples of them all. The point in the handout should help you tell the various types of trees.
As your leader tomorrow, I'll try to make the experience a rewarding one. But a field trip is a little like a bank: What you get out of it depends on what you put into it.
