Virtual radioactive dating lab
You worked in small groups and as a class to complete the "If Scientists Think. 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.
Water samples should be stored in inert plastic bottles with tightly sealed screw tops and a negligible air gap.
Samples are normally taken within the laboratory where we have all the necessary facilities.
Scientists have developed technology that can accurately date rocks using radioactive materials which are fixed into the rocks as they form from sediments.The Carbon-14 method measures the amount of radioactive carbon-14 in a previously living artifact.From this information, scientists can accurately infer the age of the test material.Please contact the lab if you require sampling to be done at another location of if particular expertise might be required that we don't have in-house.In Assignment 3, we began exploring the age of the Earth. Through presentation and discussion of individual ideas, the class reached agreements as to the best way to complete each of the prompts.
If you have an incorrect answer be sure to figure out why that answer was wrong and what is the correct answer.
