ASTR1020
Final Essay Dr. Duncan
The ASTR1020 final will have an
essay question about good and bad science worth 8 points. YOU MAY CHOOSE TO DO YOUR ESSAY AHEAD OF
TIME. If so it will take the place of
the essay question on the final. The limit is one page. Do not write more. Be concise! The purpose of the question
is to allow you to demonstrate scientific
thinking as well as to – I hope – remind you that some of the stuff you
learned in this class can be useful to you in your life, after class is done.
I encourage you to refer to the common characteristics of good science and of pseudoscience that we’ve posted on the class website. Mention them specifically when you can. Be careful to put your name on your work, or we can’t give credit! Please use a computer or write very clearly.
Please choose ONE of the following topics. You are
encouraged to do any needed research. Like a good scientist, please list
any resources you use.
One choice involves using
estimates or approximate numbers. Like
we did when comparing how many marbles fit in the classroom to the number of
stars in the Milky Way, the idea is to help you understand which bigger, not to
have great accuracy. This can often help
you make better decisions.
1. Many people who are not scientists
use scientific thinking in their everyday life (in cooking; problem solving;
etc.) Describe a use you made of
scientific thinking in your life. Relate what you did to “What is Science?”
and “How to Recognize Good Science” that are posted on the class CULearn
website. Did you form a
hypothesis? Did you experiment? Did you revise your hypothesis?
2. Many people are afraid of
terrorists. (a) Estimate the number of
people killed in America by terrorists during the last 10 years
(2002-2012). (b) Estimate the number of
Americans killed in car accidents during the same period. (c) Estimate the
number who died of cancer during those 10 years (For estimates (b) and (c) it
is fine to take figures for one year and multiply by 10.) Do these figures affect any fears you
personally might have? Why or why
not? Find out (d) how much the US spends
on the military each year, and (e) how much is spent on cancer research. Do you
think this is a wise balance? [you will
not be graded on your answer, only your use of estimation] List sources of any
numbers you use.
3.
We’ve discussed that scientific thinking
is a way to “Avoid getting fooled or fooling yourself.” Read this very poignant
article
by a doctor who has an autistic child. Answer (a) what kind of conference did
the doctor’s wife attend a year or so after their son was diagnosed? What kind
of evidence had she seen? Was it
scientific? Why or why not? Refer to “How to Recognize Good Science”
posted on the class CULearn website, especially the parts in blue (b) What characteristics of Pseudoscience were present at the
conferences the doctor began attending? Refer to “Common Elements of
Pseudoscience” on our class website. (c)
Why do you think the doctor stopped thinking the “alternative medicine”
for autism was worthwhile? (d) What do
you think you would have done if you were in the doctor’s place?
4. Proponents of Intelligent Design
say that the complexity of the universe proves that it was designed by a higher
power. Is this a scientific theory? Why or why not? Note that you’re not being asked if it is true,
but if it is scientific. Relate your answer to “What is Science?”
and “How to Recognize Good Science” that are posted on the class CULearn
website. Do the proponents of Intelligent Design form a hypothesis? Do they experiment? Do they revise their hypothesis?
I
always ask this on the final exam. Any
answer is worth a small bonus.
Has this class changed the way
you think about science? If so, describe
how, and whether this is likely to affect anything you do in the future
(classes you might take, your behavior, etc.)
