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.
The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.
Teaching about Earth's history is a challenge for all teachers.

For each of the following pairs of rock layers, identify the relative dating law that would be used to determine which bed was older and which was younger. Carbon is found in two forms in the atmosphere, carbon-14 and carbon-12.
For each of the following pairs of rock layers identify the relative dating law that you used to determine which bed was older and which was younger. Radiocarbon dating can be used to date organic material from less than 1000 years to as much as 50,000 years in age.
