WARNING!!

• SOME OF THE THINGS IN HERE ARE MIXED UP!

SCIENTIFIC INQUIRY

• A PROCESS USED BY SCIENTISTS TO STUDY THE NATURAL WORLD.

• SCIENTIFIC INQUIRY OFTEN BEGINS WITH A PROBLEM ABOUT AN OBSERVATION.

POSING OUESTIONS• QUESTIONS COME FROM

EXPERIENCES, OBSERVATIONS, AND INFERENCES YOU MAKE AND HAD.

• SCIENTIFIC QUESTIONS ARE QUESTIONS THAT CAN BE ANSWERED BY MAKING AN OBSERVATIONS AND GATHERING EVIDENCE.

• QUESTIONS ADOUT PERSONAL OPINIONS ARE NOT SCIENTIFIC QUESTIONS.

DEVELOPING A HYPOTHESIS

• A HYPOTHESIS IS A POSSIBLE EXPLANATION OR ANSWER TO A SCIENTIFIC QUESTION.

• A HYPOTHESIS IS A POSSIBLE EXPLANATION.

• IT CAN BE PROVED OR DISPROVED WITH AN INVESTIGATION.

DESIGNING AN EXPERIMENT

• BEFORE YOU START TO DESIGN AN EXPERIMENT TO TEST YOUR HYPOTHESIS, FIRST YOU HAVE TO STATE A HYPOTHESIS.

• A VARIABLE IS A FACTOR THAT CAN CHANGE IN AN EXPERIMENT.

• A CONTROLLED EXPERIMENT IS AN EXPERIMENT IN WHICH ONLY ONE VARIBLE IS CAGED AT A TIME.

• THE INDEPENDENT VARIABLE (MANIPULATED VARIABLE) IS A VARIABLE THAT IS CHANGED ON PURPOSE.

• THE DEPENDENT VARIABLE (RESPONDING VARIABLE) IS THE FACTOR THAT MAY CHANGE IN RESPONSE TO THE INDEPENDENT VARIABLE.

• A STATEMENT THAT DESCRIBES HOW TO MEASURE A PARTICULAR VARIABLE OR DEFINE A PARTICULAR TERM.

COLLECTING AND INTERPERTING DATA

• FACTS, FIGURES, AND OTHER EVIDENCE THET A SCIENTIST GATHER BY ODSERVATION ARE CALLED DATA.

• GRAGHS SHOW PATTERNS AND GRAGH OF DATA CAN BE VERY USEFUL FOR INTERPRETING DATA.

MAKING A PREDITION• A PREDITION IS WHAT

YOU THINK WILL HAPPEN NEXT.

• PERDICTING INVOLVES MAKING AN INFERENCE ABOUT A FUTURE EVENT BASED ON CURRENT EVIDENCE OR PAST EXPERIENCE.

• BECAUSE A PERDICTION IS AN INFRENCE, IT MAY PROVE TO BE FALSE.

AN OBSERVATION• WHEN YOU USE ONE OF YOUR FIVE

SENCES TO GATHER INFORMATION, THAT CALLED OBSERVING.

• AN OBSERVATION MUST BE AN ACCURATE REPORT OF WHAT YOUR SENCES DETECT.

• AN OBSERVATION IS LIKE DESCRIBING WHAT YOU SEE, HEAR, TASTE, SMELL, AND TOCH .

INFERRING• WHEN YOU INTERPET AN

OSERVATION , YOU ARE INFERING.• AN INFRENCE MAY TURN OUT TO

BE INCORRECT.

DRAWING CONCLUSIONS

• A STATEMENT THAT SUMS UP WHAT YOU HAVE LEARNED FROM AN EXPERIMENT.

• YOU NEED TO DECIDE WHETHER THE DATA YOU COLLECTED SUPPORT YOUR EXPERIMENT BEFORE YOU CAN DRAW CONCLUSIONS FROM IT.

• SOMETIMES, CONCLUSIONSLEAD TO POSE A NEW QUESTIONS AND PLAN A NEW EXPERIMENTS TO ANSWER THEM.

THE DIFFRENCE BETWEEN A HYPOTHESIS AND A

PERDICTION.• A HYPOTHESIS IS A POSSIBLE

EXPLANATION FOR A SET OF OBSERVATIONS OR A ANSWER TO A SCIENTIFIC QUESTION.

• A PERDICTION IS WHAT YOU THINK WILL HAPPEN NEXT AFTER THE EXPERIMENT (EDUCATED GUESS).

CLASSIFING

• CLASSIFIYING HELPS YOU STAY ORGANIZED .

• BY PUTTING THE SUBJECT, CLASS, NAME, AND DATE HELPS YOU FIND THINGS FAST.

MAKING MODELS• MAKING MODELS

INVOLVES MAKING REPRESENTIONSOF COMPLEX OBJECTS.

• THEY HELP PEOPLEUNDERSTAND IT.

QUANTITATIVE AND QUALITATIVE.

• QUANTITATIVE=OBSERVATIONS WITH NUMBERS, RULERS, BALENCES,BEAKERS, AND THERMOMETERS.

• QUALITAVE= OBSERVATIONS USING YOUR FIVE SENSES (TOUCH, SMELL, HEAR, TASTE, AND SIGHT.)

SCORES!!!!!!!• I WANT TO KNOW HOW MANY

EXSTRA POINTS I GOT. SCORE:

THANKS FOR WATHING!!!!!!!!!!!!!!!!!
