Next, label each bag with a number (1-5), put it at a separate station around the room, and make a sign that identifies the parent isotope type and color, daughter isotope type and color, and half-life.

Matter is made of minute particles called atoms, and atoms are composed of even smaller components.

These components have measurable properties, such as mass and electrical charge.

This predictability can be used to estimate the age of materials that contain radioactive isotopes.

Geologic time can be estimated by observing rock sequences and using fossils to correlate the sequences at various locations.

Plus, get practice tests, quizzes, and personalized coaching to help you succeed.

Free 5-day trial This quiz and corresponding worksheet will help you gauge your knowledge of radiometric dating methods and half-life through questions that test your understanding of what radioactive decay is as well as knowing what a material's half-life is.Radioactive isotopes are unstable and undergo spontaneous nuclear reactions, emitting particles and/or wavelike radiation.The decay of any one nucleus cannot be predicted, but alarge group of identical nuclei decay at a predictable rate.The bag itself represents the fossil and the beads inside represent some of the millions of atoms that make it up.As scientists, their job is to count the number of parent and daughter isotope atoms in each bag, and from this data to determine how many half-lives the isotope has gone through and therefore the age of the rock.Current methods include using the known decay rates of radioactive isotopes present in rocks to measure the time since the rock was formed.
