Material Detail
Who's on First: A Relative Dating Activity
In this activity, students are introduced to sequencing and geologic time through relative dating techniques. Students begin by categorizing cards of nonsense words, then move on to cards with pictures of fossils. Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history. There is a teacher's guide to this activity with background information and templates to use for teaching about relative dating. There are also objectives, materials, procedure, and questions.
