The geologic time scale was initially developed by determining the relative ages of rock units, first in Europe, and then in other parts of the world. Most of this work was done in the s and s. To determine which rock units were older and which ones were younger in a relative sensegeologists devised a number of laws, or principles, to help figure out the sequence of geologic events in a particular locality.

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy layers of rock are called strata. Relative dating does not provide actual numerical dates for the rocks.
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.
As many us work on developing online courses we have to ask ourselves how to implement lab activities. Listed below are some example lab activities that you might find useful as examples of others have used or even as lab activities to have your students do. Please make sure when using these activities to acknowledge the authors of the page.

SNAPs Lab Stations require students to use science, math, literacy, problem-solving and engineering skills. They are designed to enhance students' understanding of scientific concepts and help students apply scientific ideas. Each station activity promotes skills so to develop students into proficient and competent scientific thinkers. Apply the law of superposition and the principle of original horizontality to relatively date rock strata.
Use relative dating techniques to explain how the structures of the Earth. Understand the geologic time scale and Earth's. Earth science lab relative dating.
