The clocks in rocks
2. Earth is 4.6 billion years old 2.1 Earth’s rocks and other materials
provide a record of its history ▪ Fossil record and radiometric dating
2.7 Over Earth’s vast history, both gradual and catastrophic processes have produced enormous changes

Using popcorn to simulate radioactive decay
http://serc.carleton.edu/quantskills/activities/popcorn.html
Popping popcorn in your class is an excellent way to illustrate both the spontaneity and irreversible change associated with radioactive decay. It helps students to understand the unpredictability of decay.

Sample Online ActivityRock Correlation
http://msnucleus.org/membership/html/jh/earth/stratigraphy/index.html
Correlate the appropriate rock units by drawing a line between the cores.
You are given one clue in defining bed "A." Color the appropriate units and name them logically.
Make a legend so your teacher can easily see the results.
Describe what units are missing in section 3.

After having talked about the geologic time scale, get two volunteers from the class to hold a rope that is 50 feet long. Say that one end is the beginning of the Earth (4.6 billion years ago), and the other is today. Then give out 16 clothes pins and ask various students to put a clothes pin on the 'time line' at various 'geologic events'. Throughout the activity you can have students calculate percentages of Earth History for major geologic events, and compare it to their own ages. On their time scale, the
dinosaurs died only about two 'months' ago! The exercise is very effective at letting them get a sense of how long geologic time is, and how 'recently' some major geologic
events happened when you consider a time scale that is the age of the earth.
