Front 4

Empirical Evidence

Back 4

includes observations and measurements.

Front 5

community consensus

Back 5

whatever information one scientist collects, other must be able to see comment upon it

Front 6

Scientific Explanation

Back 6

Provides a description of how a process in nature occurs.

Front 7

Observation

Back 7

using our senses to gather evidence

Front 8

Curiosity

Back 8

Scientist are curious about the world around them.

Front 9

Creativity

Back 9

Original; Thinking for one self

Front 10

Logic

Back 10

reasoning through information and making conclusions supported by the evidence

Front 11

skepticism

Back 11

you don't accept everything your hear or read immediately

Front 12

Objectivity

Back 12

requires that you set aside your personal feeling, moods, and beliefs while you evaluate something

Front 13

Scientific Theory

Back 13

A system of ideas that explains many related observations is supported by a large body of evidence acquired through scientific investigation

Front 14

experiment

Back 14

an organized procedure to study something under controlled conditions.

Front 15

variable

Back 15

any factor that can change in scientific investigation

Front 16

independent variable

Back 16

the factor that is deliberately changed in an investigation (manipulated)

Front 17

dependent variable

Back 17

changes as a result of changes to the independent variable. It is the variable that we measure. It is also called the responding variable

Front 18

constant

Back 18

the parts of the experiment that remain the same.

Front 19

control

Back 19

that part of the experiment that is identical to the experimental group except that the independent variable is not manipulated

Front 20

replication

Back 20

occurs when other scientists repent a particular part of an experiment.

Front 21

repetition

Back 21

when Scientists repeat their own experiment and come out with the same results

Front 22

hypothesis

Back 22

State a possible explanation to a question. Usually stated in an "If......Then... " statement.

Front 23

qualitative observation

Back 23

observations gathered through our senses

Front 24

quantitative observation

Back 24

observations gathered using scientific tools such as a balance, a metric ruler or graduated cyclinder; These observations always have number

Front 25

Scientific Notation

Back 25

a way that scientists write very large or very small numbers

Front 26

repeated trial

Back 26

An experiment is repeated one or more times in exactly the same way by a scientist

Front 27

data table

Back 27

tool used to collect information during an experiment

Front 28

control group

Back 28

used for comparison in an controlled experiment; what we usually do

Front 29

experimental group

Back 29

the group that we change the independent variable to see if it has an effect

Front 30

two groups in an experiment

Back 30

control and experimental

Front 31

analyzing data

Back 31

look for trends and patterns

Front 32

data

Back 32

information and measurements gathered by experimentation that be used in calculating or reasoning
