Study Guide - Introductory
mind seems to have become a kind of machine for grinding general
laws out of large collections of facts, but why this should have
caused the atrophy of that part of the brain alone, on which the
higher tastes depend, I cannot conceive. A man with a mind
more highly organized or better constituted than mine, would not.
I suppose, have thus suffered; and if I had to live my life again, I
would have made a rule to read some poetry and listen to some music
at least once every week; for perhaps the parts of my brain not
atrophied would have been kept active though use. The loss of
these tastes is a loss of happiness, and may possibly be injurious
to the intellect, and more probably to the moral character by
enfeebling the emotional part of our nature.
Objectives: Upon completing this unit you should be able to:
Important Terms/Concepts: Can you use the following terms conversationally?
Freeman, Chapter 1.
Check out the Powerpoint - Science in the public folder
I have web notes about Science & Life posted online.
Supplemental Readings: (copies available in the file box in the botany lab)
Frieden, E. 1972. The Chemical Elements of Life. Scientific American. June. An interesting article concerning the elements of life, their function and factors in their selection.
Morowitz, H. 1979. The Six Million Dollar Man. In The Wine of Life. A great essay concerning the molecular constituents of life and their relation to the laws of thermodynamics.
H. 1979. Manufacturing A Living Organism.
The Wine of Life.
Another great essay concerning the
possibility of creating life in a test tube.
Rensberger, B. 1980. Life In Limbo. Science 80. A super essay about freezing and dehydration experiments.
Some Study Questions:
List the categories in the Linnean taxonomic hierarchy (hint: King David Cried Oh For Goodness Sake). Which is the most inclusive group? Least inclusive?
Compare and contrast deductive and inductive logic. Give examples of each
Identify some of the characteristics of life.
Suggest why it is difficult to define "life"
Define paradigm and give some examples
What is meant that science is a "way of knowing"?
Explain what it means that a hypothesis must be testable and falsifiable
What is Occam's razor?
What is a control group and why are they important?
Describe the four major types of scientific activities and give examples of each
What is a fact? Why is it difficult to determine what is meant by fact?
Can you outline the major steps of the "scientific method?"
read the chapters before class
take copious notes in class
reread the chapter after class with your notebook open. Record any notes from teh book directly into your lecture notes. Check your lecture notes for accuracy. Complete unfinished sections, add transistins, etc.
Answer the questions at the end of the chapter
Answer the questions on the CD and website.
Multiple Choice: (there may be more than one correct answer for some; from Freeman's text)
How does the word theory in science differ from its use in everyday English?
There is no difference � the terms are interchangeable.
All scientific theories have stood the test of time.
Scientific theories are not based on guesswork. They explain scientific laws.
Scientific theories are testable explanations, not speculative guesses.
2. Environments all over the world are changing as a result of global warming. Will this cause natural selection to occur?
The environment is always changing. Global warming is nothing new.
Traits that help individuals produce more offspring in warmer environments will increase in frequency.
The only change will be that species from hot environments will expand their ranges.
Mutations occur more frequently in hot environments.
3. Why did the five-kingdom system of classification fall out of favor?
It was too complex�the original two-kingdom system of Linnaeus was more useful.
It was too difficult to distinguish plants from fungi and animals from protistans.
There were too many monerans to be included in a single kingdom.
It did not reflect the actual evolutionary relationships among organisms very well.
4. On an evolutionary tree, any group that includes a common ancestor and all of its descendants is called monophyletic (�one-tribe�). Draw the tree for Bacteria, Archaea, and Eukarya. Are prokaryotes monophyletic?
5. A friend of yours calls to say that his car would not start this morning. He asks for your help. You say that you think the battery must be dead, and that if so, then jump-starting the car from a good battery will solve the problem. In doing so, you are:
stating a hypothesis for why the car won�t start.
searching for observations that might inspire a hypothesis for why the car won�t start.
stating a prediction and a specific hypothesis about why the car won�t start.
performing an experimental test of a hypothesis for why the car won�t start.
