Front 2

Scientific Method is:

Back 2

A universal approach to scientific problems

Identify a problem

Back 3

Always in the form of a question

Educated guess in the form of "if, then, because"

Front 6

Setting up a controlled experiment

Back 6

Only 1 variable is tested

Front 7

Control group

Back 7

The group that does not have the variable that is going to be tested

Front 8

Experimental group

Back 8

The group that does have the variable that is going to be tested

Front 9

Back 9

The variable that you record/observe

Front 10

Independent variable

Back 10

The variable that you control/manipulate

Front 11

Record/analyze results

Back 11

Put data in graphs, tables, diagrams, and charts and analyze results, see if it supports your hypothesis

Back 20

Also called life functions and are carried out by all organisms

Front 27

Respiration (not breathing)

Back 27

Converting energy from food into energy to be used by an organism

Front 28

Excretion

Back 28

Extraction of metabolic wastes

Metabolic waste product examples

Back 29

Water, salt, urea, carbon dioxide, heat

Front 30

Synthesis

Back 30

Creating more complex materials from smaller and less complex ones

Front 31

Examples of synthesis

Back 31

Glucose into starches, amino acids into proteins

Front 32

Regulation

Back 32

Control and coordination of an organism by a nervous system, adaptations to changes in environment

Front 33

Stimulus

Back 33

Change in the environment

Front 34

Response

Back 34

Reaction to the stimulus

Front 35

Growth

Back 35

Increase in size or number

Front 36

Cancer

Back 36

Uncontrolled cell growth

Front 37

Reproduction

Back 37

Is not necessary for organisms survival butt and is the passing down of genetic information and production of new individuals

Front 38

Metabolism

Back 38

The sum total of all life processes needed to survive

Front 39

Homeostasis

Back 39

An organism's internal balance if this was not a thing you would die and it requires a stable internal environment

Front 40
