Archbishop Ussher took the genealogies of Genesis, assuming they were complete, and calculated all the years to arrive at a date for the creation of the earth on Sunday, October 23, 4004 B. Of course, even assuming the method was valid, such an exact date is not possible from the genealogies of the Bible (Ussher assumed all the years the patriarchs lived were exactly 365.25 days long and that they all died the day before their next birthday).
There are a number of other assumptions implicit in the calculation.
In reality, the Bible makes no claim as to the age of the earth, although it does establish a minimum age.
This page examines some of the history of the controversy—what the Bible actually says and does not say—and the scientific evidence surrounding the age of the earth.

Games with manipulative or computer simulations should help them in getting the idea of how a constant proportional rate of decay is consistent with declining measures that only gradually approach zero.The exercise they will go through of predicting and successively counting the number of remaining "mark-side up" candies should help them understand that rates of decay of unstable nuclei can be measured; that the exact time that a certain nucleus will decay cannot be predicted; and that it takes a very large number of nuclei to find the rate of decay.This lesson can be done in two, 45-minute class periods.The Scale of the Universe from Big to Small (youtube) The Scale of the Universe from Small to Big (youtube) NASA Astronomy Picture of the Day (APOD) The Scale of the Universe - Interactive (manual control scale) Sizes (nano) Stars and Galaxies started to form.Reionization marks the point at which the hydrogen in the Universe became ionized.The attributes of naturally decaying atoms, known as radioisotopes, give rise to several applications across many aspects of modern day life (see also information paper on The Many Uses of Nuclear Technology).
