Teaching about absolute dating

posted by | Leave a comment

But absolute dating methods are not always useful; the particular circumstances to which they apply do not exist at every site. Dating methods, such as radiocarbon dating, dendro-chronology or tree-ring dating, and potassium-argon dating, that may furnish an date for an archaeological site, are a contribution of the physical and the natural sciences.In such cases subjective element cannot be ruled out.But, for a single culture site the method is quite reliable.Basing on this principle, the cultural assemblages found in different layers can be assigned a chronological personality. In practice it is found that the mounds are disturbed9 by all sorts of pits and dumps.

Understand how decay and half life work to enable radiometric dating.You might ask students to picture a pile of newspapers that have been stacked every day for a week.The oldest newspaper will be on the bottom, the remainder stacked in relative chronological order from the oldest to the latest edition.The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.According to this method, the upper deposits are younger and the lower deposits are older.
