Relative vs absolute dating worksheet

Locally, physical characteristics of rocks can be compared and correlated.

They will excavate a hypothetical archaeological site from their school yard, make observations, and write an interpretation of the history of the area based on the evidence they will excavate.

To facilitate the activity, the teacher will provide some introduction to absolute dating principles through the Half Life of M&M Worksheet.

In this activity, students begin a sequencing activity with familiar items — letters written on cards.

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.

INTRODUCTION Scientists have good evidence that the earth is very old, approximately four and one-half billion years old.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers.Specific rock formations are indicative of a particular type of environment existing when the rock was being formed.*Earth and Space Science: Fossils provide important evidence of how life and environmental conditions have changed.The complete "Paleontology and Dinosaurs" module takes approximately four weeks to teach. " activity is a 30-minute introduction to geologic time.PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.
