Question Description

this is a lab exercise which 2 of 3 need to be done. I'm not sure how to beginning or how to do them and looking for help. 1. includes steps of the scientific method and a historical problem. 2. making a geological time scale and explain the Eons, Eras, and Periods. 3. research the steps in the process of radiometric decay from parent uranium -238 to lead -206.

Ive attached the instructions.

the book we use is The Earth Through Time

Lab Exercise: After reading Chapters 1, 2 and 3 from the class textbook, complete the following assignment. Create a Word document that includes any 2 of the following. Assignment Parts-Choose Two (2) Part 1 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.

Part 2 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 document. Part 3 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. Other useful sources: University of Colorado . Radioactive Dating Game. 2011. PhET Interactive Simulations.

Remember to properly cite your sources of information* Cite all sources of information, including the textbook, using MLA formatting (http://owl.english.purdue.edu/owl/resource/747/13/ (Links to an external site.)Links to an external site.). You must include a Works Cited section as well as in-text citations of sources used. Assignments with more than 20% direct quotations from other sources will not receive any credit. ...

Part 1

The scientific process is the procedure that involves experimenting that helps derive
observations and answer questions. The fundamental objective of this process is to come up with
as precise answers to problems as possible through questioning, analyzing evidence and
combining the gained knowledge into one comprehensive solution. The process begins with an
observation that makes the observer ask a question. The question bases its idea on why a
particular situation behaves the way it does or does not act as it should. The way to approach the
problem is then analyzed, and a concrete method of approach made which is what constitutes the
step of background research (Starck, pg.5). From the question raised, a simple answer given is
called the hypothesis which is an attempt to answer the question with testable reasoning.
The hypothesis is the observer’s probable or speculated reason for the behavior and is
used as the basis for the research because it undergoes testing for precision in the process of
testing the hypothesis. Viability is tested by adjusting different variables in the assumption each
at a time to avoid biases in the test. The results can also be tested again to ensure a higher level
of confidence when communicating the derived information....
