Radioactive dating lesson
Read the passage in this science printable to learn about the history of radioactive dating and its uses.Students will answer comprehension questions and solve word problems using a table with information about the half-lives of radioactive elements.What is the process of carbon dating, and can the results be believed?Through the use of an interactive Web site, students will learn about C-14 and C-14 dating.Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.Carbon, uranium and potassium are just a few examples of elements used in radioactive dating.Each element is made up of atoms, and within each atom is a central particle called a nucleus.
In this video I walk you through using the simulation.Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.
