These differing rates of decay help make uranium-lead dating one of the most reliable methods of radiometric dating because they provide two different decay clocks.

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.

Interactive sites to help students practice skills needed for the Biology Gateway exam Cells | Interactions | Photosynthesis and Respiration Genetics and Biotechnology | Diversity | Biological Evolution Online Biology Book - every chapter is filled with great illustrations Interactive Animations - Anatomy & Physiology I - Animations, Movies & Interactive Tutorial Links [This expired link is available through the Standard 3 Photosynthesis and Respiration The student will compare and contrast the biochemical processes involved in the transfer of energy during photosynthesis and respiration and analyze the major chemical cycles in the biosphere.

Standard 4 Genetics and Biotechnology The student will investigate the concepts of genetics and heredity, different methods of reproduction, patterns of inheritance, and genetic disorders; as well as, explore and evaluate DNA technologies from both a scientific and ethical perspective.

Students learn through texts, videos, online tutorials, as well as through hands-on and virtual laboratory experiments. Materials List for home labs Also, a scientific calculator is required, particularly for performing p H calculations in Unit 11. Note: This course may require more study and practice than other courses due to the complexity of some aspects.

The final exam will be created from your tests from throughout the course.

When the isotope is halfway to that point, it has reached its half-life.

There are different methods of radiometric dating that will vary due to the type of material that is being dated.

Course Description: This course is based on Georgia Virtual Learning’s High School Chemistry course but uses other resources throughout.

This curriculum includes topics such as matter, atomic theory, the periodic table of the elements, bonding, chemical equations, chemical bonding, stoichiometry, gas laws, acids, bases, and salts, reaction rates, thermonuclear and nuclear chemistry, and equilibrium.
