Virtual radioactive dating lab
In addition to the "relative" uncertainty that the geological features of an area have retained their historical integrity, there is another problem associated with relative dating.
By looking at layers of rocks, scientists can tell which layers are older or newer than others; however, they can not tell exactly how old these layers are.
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! As you proceed through Assignment 4, be sure to compare your answers from "If Scientists Think. ." to the actual methods scientists use to estimate the age of prehistoric objects.
Because this assignment is linked with your work in Assignment 3, you will have "If Scientists Think. Before scientists had modern technology to assist them in their research, they had to use their power of observation to infer the relative ages of the rocks they were studying.
All samples submitted to the laboratory must be accompanied by a sample submission form that gives the details of the sample we need. In addition, we would ask submitters to look at our Policy on the dating of Antiquities and sign our terms and conditions.
If you are unable to submit the form online for any reason spreadsheet or paper forms can be sent (please contact our administrator).
You have probably heard of mummies that have been dated with the Carbon-14 method.After all, it is possible that rock layers can be disturbed, overturned, and altered in both natural and unnatural ways.Who's to say that the rocks a particular scientist is studying have not been displaced from their original positions?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.
