1.3 Scientists Use Two Main Forms Of Inquiry In Their Study Of Nature

Front 1

Inquiry

Back 1

the search for information and exploration, often focused by specific questions

Front 2

Discovery science

Back 2

The process of scientific inquiry that focuses on describing nature

Front 3

Data

Back 3

recorded observations

Front 4

Inductive reasoning

Back 4

A type of logic in which generealizations are based on a large number of specific observations

Front 5

Hypothesis

Back 5

A tentative answer to a well-framed question-- an explanation on trial.

Front 6

Deductive reasoning

Back 6

A type of logic in which specific results are predicted from a general premise

Front 7

"if... then"

Back 7

A type of deductive testing

Front 8

falsifiable

Back 8

There must be some observation or experience that could reveal if such an idea is actually not true

Front 9

Testable

Back 9

There must be some way to check the validity of an idea

Front 10

The Scientific Process

Back 10

An idealized process of inquiry

Front 11

Experimental group

Back 11

The part of an experiment that when compared to the other group, shows the difference. (Ex: the saltwater compared to water)

Front 12

Control Group

Back 12

The group that stays constant in an experiment

Front 13

Theory

Back 13

An explanation that is broad in scope, generates new hypothesis and is supported bya large body of evidence

Front 14

Models

Back 14

Can take many forms, including diagrams, 3-D models, graphs, computer programs, and mathematrical equations

Front 15

Technology

Back 15

Generally applies scientific knowledge for some specific purpose
