BES 301 – Scientific Methods / Class notes Jan. 11th

Critical thinking involves attitude qualities: argue (healthy skepticism based in evidence to support the claim), apply, synthesis, evaluate.
Collaboration: ask your peers questions. What haven’t you thought about yet? Paraphrase the essence. Working as a team, write it in the workbook. Present in the paper.

For the Nucella (genesis) lamellosa (species) – “dogwelk” we’ll manipulate experiments and generate a hypothesis to test. When you critically think, you are trying to understand fully.

Start with a hypothesis: Introduction, materials and methods, results (observations, data and statistical conclusion – show results), Discussion (interpretation, informal presentation: notes, tests). Make a prediction and test the hypotheses.

What kind of tests are needed to “conduct” an answer?
The tests that Kuhl used included direct (physical structure of the mouth and throat, acoustic analysis, and pitch frequency, use of the meglatone), and indirect observation (linguistic hot spots, relationship of observed phenomena).

How do we know completely what sustainability is? We’re adding to the soup of chemicals.
Small changes in genes complete reorganize the organism

“Chicken” – there is a certain amount of predictability: intro, M&M, results (IMRaD)
What kind of experiments (mesocosm – replicate, or control, the environment)

The abstract varies from the introduction because it includes IMRaD.
Hypotheses: Do environmental factors inhibit growth in lamellosa?
1. There were intermittent treatments, and a control group
2. Interruption was more beneficial than duration
3. Air retards hard and soft tissue growth
4. Factors included tidal emersion and eating
A sub question: How does the time affect growth?
