What is the definition of scientific method |
Systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses |
|
|
|
Order of scientific method |
Observations -> questions -> hypotheses -> predictions -> experiment ->theory. |
|
|
|
Science is only able to investigate questions that are... |
Measurable (quantifiable) |
|
|
|
For a question to be pursued scientifically.... |
The phenomenon must be well-defined and testable. |
|
|
|
Question: the elements must be.. |
Measurable and controllable. |
|
|
|
Define hypotheses |
A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. |
|
|
|
Languages used in a hypotheses is... |
Objective and quantifiable |
|
|
|
Predictions are... |
Logical conclusion to be expected in view of the research hypothesis |
|
|
|
Predictions are usually what types of statements? |
“If...then..” |
|
|
|
What is a null hypothesis |
A statement which identifies that the outcome in the experimental group will be the same as the control group |
|
|
|
What are the three different types of variables |
Independent variables, dependent variables, controlled variable |
|
|
|
What is an independent variable |
The factor being manipulated by the researcher |
|
|
|
What is dependent variable |
The factor we expect to change when we manipulate the independent variable |
|
|
|
Controlled variables |
All other factors that may affect the outcome of the experiment and so much be controlled or kept constant |
Don’t get confused with the control group |
|
|
Research groups are divided into two groups... |
Experimental group and control group |
|
|
|
Define experimental group |
The group that is exposed to the independent variable |
|
|
|
Define control group |
The group that does not receive treatment |
Don’t get confused w/ the controlled variables |
|
|
Why is replication important |
Because experiments are not valid off of one instance and there for needs multiple replicates to see the average results |
|
|
|
What is a theory |
A hypothesis which has been tested and repeatedly supported |
|
|
|
What draws a theory |
A hypothesis being tested in multiple different ways and still being supported |
|
|
|

25 |
|
|
|
What is the termination in transcription |
Poly-adenylation signal |
|
|
|
What is the termination in transcription |
Poly-adenylation signal |
|
|
|
What initiates translation? |
ATG |
|
|
|
What is the first amino acid in every polypeptide |
Met- methionine |
|
|
|
Termination in translation is... |
Either UGA, UAA, UAG |
