Atomic dating using isotopes lab report

Far from being data, these dates are actually interpretations of the data.As discussed before, the assumptions influence the interpretation of the data.This is not true for zeroth- and second-order reactions.The half-life of a first-order reaction is independent of the concentration of the reactants.Recent research by a team of creation scientists known as the RATE (arth) group has demonstrated the unreliability of radiometric dating techniques.Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.If two reactions have the same order, the faster reaction will have a shorter half-life, and the slower reaction will have a longer half-life.

This is the first in a three-lesson series about isotopes, radioactive decay, and the nucleus.

Students should be able to describe an atom and its basic structure.

This lesson helps students understand the important notion that neutrons in the nucleus add to an atom's mass.

Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.

The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.

Prerequisite understanding for this lesson can be found at the 6-8 level, particularly the idea that "atoms of any element are alike but different from atoms of other elements." (4D Structure of Matter (6-8) #1) The ideas in this lesson are essential for building an understanding of the concept that the nucleus of radioactive isotopes spontaneously decays.
