Teaching about Earth's history is a challenge for all teachers. Time factors of millions and billions of years is difficult even for adults to comprehend. However, "relative" dating or time can be an easy concept for students to learn. Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards. Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata. Once students begin to grasp "relative" dating, relative dating worksheet middle school can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history. These major concepts are part of the Denver Earth Science Project's "Paleontology and Dinosaurs" module written for students in grades
A Relative Dating Activity is a hands on exercise which introduces students to the concepts of sequencing and using fossils to establish relative dates for rock strata. In the first part of the activity, students are asked to sequence cards by identifying and ordering overlapping letters found on the cards. In the second part of the activity, students progress to dating rock layers by sequencing fossils found in the different strata. Using the results of these activities, teachers can then lead students in a discussion of the Law of Superposition and the identification and value of index fossils. It should be noted that teachers may have to edit the introductory materials provided to students, since the relative dating worksheet middle school may be too difficult for younger middle school students. Both parts of the activity can be completed in one class period.

A good way to introduce the concept of rock sequencing is to present each step with a separate sketch. We usually just give students the finished product and many students have trouble with seeing how the finished diagram came to be. Here are a couple of good sequencing games. I give each team the four relative dating worksheet middle school along with 4 sticky notes. They have to put the sketches in order and put a sticky label with each sketch explaining what cause the change in each sketch.
