Why Lesson Planet?
Digital pictures from a field trip to the zoo launch a research unit for 3rd through 6th graders. Over 6 weeks, your young researchers develop skills at locating information from various resources -- with keyword searches, in magazines and books. They conduct research, take notes, compile bibliographies, and create a book to present their knowledge. Instead of lectures as listed, I'd prepare hands-on activities to get them moving in the library and on the internet.
