Q

Temperature

A

The basic unit of measurement for temperature is Kalvin.

Celsius is also used, but not the official one.

31
Q

Time

A

Basic unit to measure time is seconds

32
Q

What math skills do scientist use?

A

Estimation, accuracy and precision, and significant figures

33
Q

Estimate

A

Approximation of a number based on reasonable assumptions

34
Q

Accuracy

A

How close a measurement is to the true or excepted value

35
Q

Precision

A

How close a group of measurements are to each other

36
Q

Significant figures

A

Measurement include all digits measured exactly, plus one estimated digit

37
Q

What math tools do scientist use?

A

Calculating percent error’s, finding the mean, median, mode, and range, and checking the reasonableness of data

38
Q

Mean

A

The numerical average of a set of data

39
Q

Median

A

The middle number of a set of data

40
Q

Mode

A

Number that appears most often in a list of numbers

41
Q

Range

A

the difference between the greatest value in the least value in a data set

42
Q

Percent error

A

Calculations are a way to determine how accurate and experimental value is

43
Q

Anomalous data

A

Data that do not fit with the rest of the data set

44
Q

Graph

A

A picture of your data

45
Q

Process

A

A process is a series of actions or events

46
Q

Line graph

A

Display data that shows how one variable changes in response to another variable.

Powerful tools in science because they allow you to identify trends, make predictions, and recognize anomalous data

47
Q

Linear graph

A

Line graph in which data points yield straight line

48
Q

Nonlinear graph

A

A line graph in which the data points do not fall along a straight line

49
Q

What is scientific inquiry?

A

Refers to the diverse ways in which scientists study the natural world and propose explanations based on evidence they gather

50
Q

Hypothesis

A

A possible answer to a scientific question

51
Q

Experiment

A

Must follow sound scientific principles for its results to be valid

52
Q

Controlled experiment

A

Experiment in which only one variable is manipulated at a time

53
Q

Data

A

Facts, figures, and other evidence gathered through qualitative and quantitative observations

54
Q

Repeated trials

A

Repetition of an experiment

55
Q

Replication

A

Another scientist repeats your experiment

56
Q

How do we gain scientific knowledge?

A

Observations in modeling are two other ways of gaining scientific knowledge

57
Q

Observing

A

Using your senses together information

58
Q

How do you measure volume of liquids?

A

With a graduated cylinder

59
Q

How do you measure volume of a rectangle solid?

A

Length x width x height

60
Q

How do you measure the volume of an regular solid?

A

With the graduated cylinder.

You see what the difference is when you drop the rock in the water.

61
Q

How do you measure density?

A

Density equals mass over volume

D=m/v

62
Q

Scientific theory

A

Well tested explanation for a wide range of observations or experimental results

63
Q

Scientific law

A

A statement that describes what scientists expect to happen every time under a particular set of conditions.

Unlike theory a scientific law describes an observed patterns in nature without attempting to explain it.

64
Q

Scientific explanation

A

Describe how something works or why something happens

65
Q

Empirical evidence

A

Data and observations that have been collected through scientific process

66
Q

Opinion

A

An idea that may be formed from evidence but has not been confirmed by evidence

67
Q

Controversy

A

Scientist can change society by defending their work in the face of controversy. Discovery which conflicts with the beliefs of society or its leaders.

68
Q

Scientific knowledge

A

Results of new evidence or near interpretation of existing evidence can change scientific knowledge.

69
Q

Model

A

Any representation of an object or process

70
Q

System

A

A group of parts that work together to perform a function or produce a result

71
Q

Input

A

The material or energy that goes into a system

72
Q

Process

A

What happens in the system

73
Q

Output

A

Material or energy that comes out of the system

74
Q

Feedback

A

Output that changes the system in someway
