A

Inference

22
Q

Give an example that demonstrates the difference between an Observation and an Inference?

A

Observation - “the moon is red”

Inference - “the moon is red because it’s hot” > understanding that red objects are hot

23
Q

a factor, condition, or relationship that can be changed in an experiment and can influence the outcome of an experiment

A

Variable

23
Q

a group that continues under existing conditions

A

Control Group

24
Q

a group exposed to something that’s being tested in the experiment

A

Experimental Group

25
Q

the factors or conditions in the experiment that don’t change between the control and experimental groups

A

Controlled Variables

26
Q

a variable that is purposely changed in an experiment

A

Independent (Manipulated) Variable

27
Q

How many independent variables do you change at a time in an experiment?

A

One

28
Q

Which axis is the independent variable vs the dependent variable on in graphs?

A

Independent = X-axis
Dependent = Y-axis

29
Q

the result of the change in the experimental group due to the manipulated variable

A

Dependent (Responding) Variable

30
Q

a proposed explanation for a phenomenon or problem being studied

A

Hypothesis

31
Q

What are the 2 types of hypotheses?

A
  1. Null Hypothesis
  2. Alternative Hypotheses
32
Q

How is the Hypothesis written vs how is a Prediction written?

A

Hypothesis - written as a declarative sentence

Prediction - written as an if/then statement

33
Q

What are the 2 methods of reasoning?

A
  1. Deductive Reasoning
  2. Inductive Reasoning
34
Q

examines the big picture data (very general observations) and predicts a very specific answer

A

Deductive Reasoning

35
Q

takes a very specific observation and draws broader conclusions from it

A

Inductive Reasoning

36
Q

observations that are made or measured using numbers

A

Quantitative Data

37
Q

describes, approximates, and characterizes observations in (often) non-numerical ways

A

Qualitative Data

38
Q

the papers and journals that contain published experimental results

A

Scientific Journals (Primary Literature)

39
Q

the process of subjecting experiments and their results and conclusions to scrutiny by other scientists in the same field of study

A

Peer Review

40
Q

What is a key component of reliable, high-quality science?

A

Repeatedly achieving the same results

41
Q

the interpretation, simplification, and presented conclusions by science writers that is used to make science accessible to the general public

A

Secondary Literature

42
Q

sources that are a distillation of information and are a good place to find general information about a topic

A

Tertiary Literature

43
Q

What are 5 other places where scientific info is communicated?

A

44
Q

a thoroughly tested and confirmed explanation for a set of observations or phenomena and is the foundation of scientific knowledge

A

Scientific Theory

45
Q

a socially learned behavior

A

Culture

46
Q

copying behaviors observed in others or acquiring behaviors through being taught be others

A

Social Learning

47
Q

Why do scientists share their findings?

A

So other researchers can:
1. expand
2. build upon
3. build support for
their discoveries

48
Q

Can theories be proven over time?

A

NO - common misconception is that “true” theories mature into facts

49
Q

describe how elements of nature will behave under certain specific conditions

A

Scientific Laws

50
Q

What is an example of a scientific law vs a scientific theory?
