Let's Model Radioactive Decay to Show How Carbon Dating Works

Carbon dating presentation Purpose To develop the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point. Context This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay. The first lesson, Isotopes of Pennies , deals with isotopes and atomic mass. By the end of the 8th grade, students should know that all matter is made up of atoms, which are far too small to see directly through a microscope. 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.


uses of radiocarbon dating

But it offers some practical uses. One of the coolest OK, maybe the coolest is using radioactive carbon to determine the age of old bones or plants. To understand this, you must first understand radioactivity and decay.

"Carbon-14 Dating Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium. Mostly from cosmic rays. The charge must have a certain energy in order to pass through the magnetic field. A stronger magnetic field or a particle with lower energy will cause the particle to have more trouble passing through the earth's magnetic field. This is known because other isotopes are made by cosmic rays and because of historic age information, tree rings etc..
