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.There are two techniques geologist use to obtain the Earth's age: Radioactive dating and Relative dating. The exposed rock reveals layers of different types of rocks.
Relative dating earth layers
