Inquiry of Science (lecture 2)

Question 1

What is a hypothesis?

Answer 1

A plausable explanation based on observation and assumptions that lead to a testable prediction
- building on top of other research and ideas

Question 2

What’s a control

Answer 2

Where you make sure that all the variables that could be fixed are done so that the output of that experiment is not due to any variations/changes within the that you are using

Question 3

Inductive reasoning

Answer 3

When you derive generalizations from a large # of scientific observations or data analysis. Looking at data and generalizations to make predictions , extracting a likely premise from very specific and limited observations.

Question 4

Deductive reasoning

Answer 4

Uses general premises to make specific predictions.,
initial observations can lead to multiple hypothesis, which then you test out
You know proven observation and then make a very specific prediction
more scientific than inductive reasoning

Question 5

Hypothesis order

Answer 5

inductive reasoning –> hypothesis –> experiment –> deductive reasoning

Question 6

a hypothesis must be

Answer 6

testable

Question 7

independent variable

Answer 7

is the one that is manipulated by the researchers

Question 8

dependent variable

Answer 8

is the one predicted to be affected in response

Question 9

A theory is

Answer 9

broader in scope than a hypothesis, but general enough to lead to many new testable hypothese, and is supported by a large body of evidence in comparison to a hypothesis
