Assignment Parts-Choose Two (2)
Take a look at a web page that discusses the steps of the scientific method, for
example, http://www.sciencebuddies.org/science-fairprojects/project_scientific_method.shtml (Links to an external site.)Links to an external
site.. Make note of the steps in the scientific method and what happens when the validation
of an hypothesis does not work out. Then, consider a geological problem in the area of
historical geology. Describe the steps of the scientific method in terms of that problem. If
you want ideas on possible problems for research in historical geology, be sure to read this
chapter and pick one or two other chapters in the book and look at those for ideas.

Make a geological time scale where one inch is equal to 100 million years. Plot this on a
long piece of paper. Make the geological time scale wide enough so that you can write the
names of the Eons, Eras, and Periods comfortably in the space you provide. Use the scale of
one inch to 100 million years consistently throughout the diagram you are making. When
finished, what do you notice about the distribution of lengths of time within the Eons, Eras,
and Periods? Speculate on why this is. Take a look at a web page on chronostratigraphy
(such as stratigraphy.org). Also, look at web pages on the distribution of fossils through
geological time. Take a picture of your geologic timescale and include it in your Word
Using web pages research the steps in the process of radiometric decay from parent
Uranium-238 to Lead-206. (
e.g., http://www.epa.gov/radiation/understand/chain.html (Links to an external
site.)Links to an external site.) List all the steps in the decay process, indicate whether
alpha, beta, or other decay was involved in each step, give the time required for each step
to take place (on average), and list the parent and daughter products in each step. You
should find a dozen or more steps in this decay process.
