Virtual Dating works best with Netscape Communicator 4 or Microsoft Internet Explorer 4 with Java Script enabled. It requires Netscape Navigator versions 3.0x and higher and Microsoft Internet Explorer versions 3.0 and higher.
Radiocarbon Dating of the Shroud of Turin site is a reprint of the original article analyzing the Shroud of Turin.
The time necessary for half of any given amount of one element (the “parent element”) to decay to become another element (the “daughter element”) is called the element’s “half-life.” Ice cores, for example, contain data about Earth’s past climate.
Geologists use a dating technique called K-Ar geochronology to find the age of layers of volcanic ash in ice cores. By measuring the ratio of K to Ar in feldspar crystals in volcanic ash, geologists can determine the time of the eruption and, thus, the age of ice in which the ash is found. Heating causes the kernels to begin popping, thereby starting your simulated “radioactive decay clock” and producing popped “daughter” popcorns.
" Exponential and Logarithmic Functions, Episode #3 Web Sites: Geology Labs On-line (Virtual Dating) Teacher site Dating/This site (part of Labs/) gives you the full access to all the teacher programs for virtual radioactive dating.
Check Virtual Dating Demo then Virtual Dating Radiocarbon.
Geology Labs On-line (Virtual Dating) Student site Dating/files/RC0/RC_0This site (which is identical to the above except it has the question checker enabled) gives the students access to the site.
What is the process of carbon dating, and can the results be believed?
Students should have familiarity with the scientific notation and the units milli, micro, and nano.
Students will be introduced to being science/math detectives by trying to figure out the relationship of organisms using graphs.
Once they determine the age of a volcanic ash layer, geologists can study the materials in that ice core layer for clues about climate conditions at that time. The half-life of your kernel-popcorn material is the time necessary for half of the given kernels to become popcorns.
This lesson can be used as an introduction to radioactivity.Related teaching materials and games are also linked on the website.
