THE SCIENTIFIC METHOD

Scientific Method is the way scientists learn and study the

world around them. The basis of scientific method is asking questions and then

trying to come up with answers Just about everything begins with a question and someone

has an urge to answer that question Its as easy as asking “Why do cats and dogs have hair?”

One answer could be that it keep them warm

Scientific Method is a rational, logical thought process that is used to figure out facts and truths

EXPERIMENTAL EVIDENCE IS WHAT MAKES ALL OF THE OBSERVATIONS AND ANSWER IN SCIENCE VALID (TRUTHFUL OR CONFIRMED)•Statements must be confirmed with loads of evidence• Scientist start with observations and then make a hypothesis (an educated guess)• Then starts the fun by proving the hypothesis through many different trials and test to show why the data and results are correct.• Using controls which

quantitative (based on values and figures, not emotions)

• Qualitative is pertaining to or concerned with quality or qualities•Scientist can examine their data and

develop newer ideas• This process will lead to more

observation and refinement of hypotheses.

THE WHOLE PROCESSThere are different terms used to describe scientific ideas

based on the amount of confirmed experimental evidence.

Hypothesis- a statement that uses a few observations- an idea based on observations without experimental evidenceTheory- uses many observations and has loads of experimental evidence- can be applied to unrelated facts and new relationships- flexible enough to be modified if new data/evidence introducedLaw- stands the test of time, often without change- experimentally confirmed over and over- can create true predictions for different situations- has uniformity and is universal

A model is a scientific statement that has some experimental validity or is a scientific concept that is only accurate under limited situations.

QUIZ TIME! QUESTION 1:

The scientific method was developed to help scientists organize the process of solving problems.

TrueFalse

CORRECT! The scientific method is an objective

step-by-step way of looking at natural events. When anyone has a question about the world around them, they use these methods and procedures to explain and answer that question. The scientific method can also be used to prove (or disprove) the statements of another scientist or person. The entire process requires observable and quantifiable evidence and data.

QUIZ TIME! QUESTION 2:

Which of these is not a step of the scientific method?

HypotheisExperimentConclusionPlagiary

INCORRECT!There are about six basic steps in the scientific method of solving problems. You have to start with a problem or question and then develop a

hypothesis that offers an answer to the question. You then develop and perform an experiment and record your results. You finish with an analysis of your results and develop a conclusion that would

(hopefully) answer the original question.

QUIZ TIMEQuestion 3Which of these words would you NOT

associatewith the scientific method?

Disorganized OrganizedDataControl

CORRECT!!!The scientific method creates an organized framework that helps

scientists (and everyone) solve problems. As you

complete an experiment that tests variables and has controls, you record

data and results.

A hypothesis is...

A Random ThoughtAn AnswerAn Educated GuessAn Experiment

INCORRECTA hypothesis is an educated guess that

offers a possible answer to a problem. An

experiment must be developed to prove the

accuracy of the hypothesis.

CORRECT!A hypothesis is an educated guess that

offers a possible answer to a problem. An

experiment must be developed to prove the

accuracy of the hypothesis.

QUIZ TIMEQUESTION 5:

Which of these would be called results?

Number of Fruit FliesCounting Fruit FliesSeeing Fruit Flies on an AppleWondering Why a Fruit Fly was Born

INCORRECTThe number of fruit flies

would be the only results. The other

choices are all steps in the process (Hypothesis, Experiment,

Observation).

CORRECT!!!The number of fruit flies

would be the only results. The other

choices are all steps in the process (Hypothesis, Experiment,

Observation).

QUESTION 6: What do you do to test a hypothesis?

GuessCreate a Spreadsheet with DataPublish a Scientific PaperDesign an Experiment

INCORRECTYou need to conduct a series

of procedures to test any hypothesis. The developed experiment uses variables

(changing factors) and controls (unchanging

examples).

CORRECT!!!You need to conduct a series of procedures to

test any hypothesis. The developed experiment

uses variables (changing factors) and controls

(unchanging examples).

QUIZ TIMEQUESTION 7:

A control group is used as a comparison to the group where things (variables) are changing.

TrueFalse

CORRECT!!

The control group of an experiment is a group that is not experimented on. For

example, if you wanted to see what happened when you increase UV

radiation on plants, you would have a control group that did not have any

different UV levels. They would be used as a baseline or static group in the

experiment.

INCORRECTThe control group of an experiment is a group that is not experimented on. For

example, if you wanted to see what happened when you increase UV

radiation on plants, you would have a control group that did not have any

different UV levels. They would be used as a baseline or static group in the

experiment.

QUIZ TIMEQUESTION 8:

An independent variable is a factor that changes because of procedures conducted on the dependent variable.

TrueFalse

INCORRECT!The opposite is true. A dependent variable is a

factor that changes because of procedures

conducted on the independent variable.

CORRECT!!The opposite is true. A dependent variable is a factor that changes

because of procedures conducted on the

independent variable.

QUIZ TIMEQUESTION 9:

Experiments are usually conducted one time and by one team to speed up the scientific process.

TrueFalse

INCORRECT!Experiments are performed dozens and

hundreds to times before a scientific statement is accepted as a truth. The experiment would be performed using

the same procedures. To prove the original hypothesis, the other testing team must be able to generate the

same results.

CORRECT!!Experiments are performed dozens and

hundreds to times before a scientific statement is accepted as a truth. The experiment would be performed using

the same procedures. To prove the original hypothesis, the other testing team must be able to generate the

same results.

QUIZ TIMEQUESTION 10:

Experiments often test multiple variables.

TrueFalse

INCORRECT!Experiments test for one

independent variable. There can be multiple

dependent variables that change during the

procedures.

CORRECT!!Experiments test for one

independent variable. There can be multiple

dependent variables that change during the

procedures.
