Radioactive dating worksheet middle school

The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.

In a way this field, called geochronology, is some of the purest detective work earth scientists do.

There are two basic approaches: relative age dating, and absolute age dating.

Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.

Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old.

They will select their topic, explore the criteria for planning, and design a compelling and realistic experiment based on their topic.

This lesson plan is aligned to Common Core State Standards.

Relative age dating also means paying attention to crosscutting relationships.

Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.

They should also understand that the atoms of any element are alike but are different from atoms of other elements.

Atoms may stick together in well-defined molecules or they could be packed together in large arrays.

Unlike people, you can’t really guess the age of a rock from looking at it.
