science chapter 1: intro to physical science

science

the study of matter and movement of God’s physical creation

scientific method

the orderly process by which scientist investigate the secrets of nature

observing

includes careful measurements of info, and extensive research into the observations of other scientist

hypothesizing

tentative explanation or to describe the process

experimenting

an artificial situation that more clearly shows how things happen

falsifiable

when the hypothesis can be proven false or if one or more of it’s predictions are false

repeatability

when a scientist will obtain consistent results if he preforms the same experiment many times, keeping all factors as similar as possible between experiments

reproducibility

the ability of other scientist to reach the same conclusion by preforming the same experiment under different conditions and by preforming other experiments to test the same hypothesis

variables

factors that the experimenter can potentially control to test the hypothesis

dependent variable

is observed or measured to determine the results of an experiment

independent variable

the factor that is changed to test the hypothesis

controlled variables

factors that are the same In all groups

experimental group

the groups in an experiment on which a test is performed

control group

a group in which there is no independent variable

theory

when a hypothesis pases tests of many experiments and has the support of other scientist

scientific law

when theory is verified by enough observations and experiments and stands the rest of time

principle of casualty

the principle that the universe is lawful, orderly, and operates according to physical laws

the scope of science

the study of created matter and energy in the present

bias

when human nature often leads one to see and believe what he wants to be true, not necessarily what actually is true
