Radioactive Dating Game
Our innovative, cutting edge techniques give by a large margin the highest accuracy and precision in tritium analysis . This high tritium precision allows for new understanding of processes in groundwater, oceans, and glaciers, such as. Our tracer data are used to understand and manage groundwater resources, and to understand how groundwater dynamics change over time.

Taking the necessary measures to maintain employees’ safety, we continue to operate and accept samples for analysis. Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.
Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine. Radiocarbon carbon 14 is an isotope of the element carbon that is unstable and weakly radioactive.
The stable isotopes are carbon 12 and carbon Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms. It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle. Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes. When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.
There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry. Gas proportional counting is a conventional radiometric dating technique that counts the beta particles emitted by a given sample. Beta particles are products of radiocarbon decay.

Radiometric dating–the process of determining the age of rocks from the decay of laboratory measurements that have shown these methods to be consistent.
In Assignment 3, we began exploring the age of the Earth. You worked in small groups and as a class to complete the “If Scientists Think. Through presentation and discussion of individual ideas, the class reached agreements as to the best way to complete each of the prompts. Today’s assignment will allow you to compare and contrast your ideas to some of the actual methods scientists used to develop an estimation of the age of the Earth.
Following this introduction, there are several links to different sites concerning the methods scientists use to assist them in estimating the age of the Earth. You will investigate Steno’s Laws, radiometric dating, and then visit an interactive site that will help you better understand how to tell time – with geology!

Create a model of radioactive decay using dice and test its predictive power on dating the age of a hypothetical rock or artifact. As humans, it seems easy for us to keep track of time lapses, as long as they range from a couple of seconds to a number of years. That is what we encounter in our daily lives, right?
The Earth orbits the Sun in about one year’s time, the Earth rotates on its axis every 24 hours, 60 ticks of the second hand on a clock indicates 1 minute has passed. Geologists have a much harder job keeping track of time. Studying the Earth and its evolution, they work with time scales of thousands to billions of years.
To define and distinguish between relative and radiometric methods of dating. After all, it is possible that rock layers can be disturbed, overturned, and altered in as you move through the various exercises of the Radiometric Dating Lab.
Since the early twentieth century scientists have found ways to accurately measure geological time. The discovery of radioactivity in uranium by the French physicist, Henri Becquerel , in paved the way of measuring absolute time. Shortly after Becquerel’s find, Marie Curie , a French chemist, isolated another highly radioactive element, radium. The realisation that radioactive materials emit rays indicated a constant change of those materials from one element to another.
The New Zealand physicist Ernest Rutherford , suggested in that the exact age of a rock could be measured by means of radioactivity. For the first time he was able to exactly measure the age of a uranium mineral. When Rutherford announced his findings it soon became clear that Earth is millions of years old. These scientists and many more after them discovered that atoms of uranium, radium and several other radioactive materials are unstable and disintegrate spontaneously and consistently forming atoms of different elements and emitting radiation, a form of energy in the process.
The original atom is referred to as the parent and the following decay products are referred to as the daughter. For example: after the neutron of a rubidiumatom ejects an electron, it changes into a strontium atom, leaving an additional proton. Carbon is a very special element.
