Radioactive dating lesson
Radioactive materials contain some nuclei that are stable and other nuclei that are unstable.Not all of the atoms of a radioactive isotope (radioisotope) decay at the same time.
Description: With the Half-Life Laboratory, students gain a better understanding of radioactive dating and half-lives.The sign suggests the dinosaur bone is from the Jurassic Period and is approximately 200 million years old.Then you start to wonder, "Who figured out how old the bone is, and how did they determine its age?Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
Radioactive dating is not going steady with a crazy person; it's a method of finding the age of a fossil." Start by acquiring a basic understanding of what radioactive dating is; otherwise this lesson doesn't have much value.
