ADVENTURES AT DRY CREEK

            http://www.teachersfirst.com/getsource.cfm?id=4044

You and your students are about to embark on an exciting scientific adventure based upon ongoing research of UC paleontologists studying about life in Montana 60-70 million years ago.   This may be unlike any other lesson that you have used with your students because it provides the opportunity to follow the scientific process using real research questions and data. Don't worry if answers to some of the questions are not immediately apparent. After all, scientists don't have all the answers either. This module provides a great opportunity for you as the teacher/facilitator/learner to share with your students the on-going nature of discovery that makes science thrilling.”  Excellent

“ROUND ROCKS” TEACHING THE PRINCIPLES OF EARTH SCIENCE AND PALEONTOLOGY

            http://www.ucmp.berkeley.edu/fosrec/AllGrif.html

An article on teaching earth science to teachers and high school students.  “We present this approach to paleontology and earth science in an exercise we call "round rocks." The rocks we use are not necessarily round. Indeed, we stress (and we really do mean) that it should be possible to carry out the process with literally any rock in your backyard. The process consists of taking a rock in the hand and asking a single, simple question: "How did this rock come to be this way?"  We present this exercise to two categories of audience: students (at grades 6-12) and teachers (K-12). Our one-hour presentations to students are intended to encourage them to begin to think in a new way. Our presentations to teachers are intended to encourage them to teach in a new way. During the main part of the exercise, we attempt to derive four basic principles. It is our contention that application of these four principles alone can lead to the successful interpretation of any geological hand specimen.”   Excellent
