ALL EXPERIMENTS BEGIN WITH A RESEARCH QUESTION THAT IS ________________.
TESTABLE
100
SCIENTISTS USE SOMETHING THEY ARE BORN WITH TO OBSERVE INTERESTING THINGS IN THE NATURAL WORLD? WHAT DO THEY USE?
THEIR FIVE SENSES
100
DEFINE HYPOTHESIS (DO NOT SAY EDUCATED GUESS!)
A PREDICTION THAT IS A POSSIBLE EXPLANATION FOR A SET OF OBSERVATIONS OR AN ANSWER TO A SCIENTIFIC QUESTION.
100
WHEN RECORDING AND ANALYZING DATA, SCIENTISTS ATTEMPT TO EXPLAIN THEIR OBSERVATIONS BASED ON
______________ AND ______________________.
PATTERNS, RESEARCH, OR PAST EXPERIENCES
100
THE FINAL STEP IN THE SCIENTIFIC PROCESS IS TO _______ A ___________.
DRAW A CONCLUSION
200
SCIENTIFIC QUESTIONS CANNOT BE BASED ON __________
OPINIONS OR PERSONAL JUDGEMENTS
200
WHEN CHOOSING A TOPIC TO INVESTIGATE, IS IT BETTER FOR THE TOPIC TO BE VERY BROAD OR NARROW? WHY?
NARROW SO THAT YOU CAN FOCUS ON THE MOST IMPORTANT PARTS OF THE EXPERIMENT AND RESEARCH ONLY THOSE PARTS.
200
TRUE OR FALSE:
IT IS BEST TO MAKE THE HYPOTHESIS AFTER THE EXPERIMENT.
FALSE, BECAUSE IT IS A PREDICTION OF WHAT WILL HAPPEN IN THE EXPERIMENT.
200
WHEN YOU EXPLAIN OR INTERPRET THINGS YOU OBSERVE, YOU ARE MAKING AN _____________.
INFERENCE
200
WHEN DRAWING A CONCLUSION A SCIENTIST IS CHECKING TO SEE IF THE RESULTS SUPPORT OR PROVE THE
______________.
HYPOTHESIS
300
WHICH FLOWER IS THE PRETTIEST, A ROSE OR A SUNFLOWER: IS THIS QUESTION TESTABLE? WHY OR WHY NOT?
PRETTY CANNOT BE SCIENTIFICALLY TESTED BECAUSE IT IS AN OPINION
300
THE ONE FACTOR OR CONDITION IN AN EXPERIMENT THAT IS INTENTIONALLY CHANGED IS CALLED THE __________
INDEPENDENT VARIABLE
300
JUST LIKE THE TESTABLE QUESTION, A HYPOTHESIS MUST BE _________________.
TESTABLE
300
WHAT IS AN INFERENCE?
LOGICAL EXPLANATIONS THAT HELP US MAKE SENSE OF WHAT WE OBSERVE.
300
TRUE OR FALSE:
IF THE CONCLUSION DOES NOT SUPPORT THE HYPOTHESIS, THE EXPERIMENT IS A FAILURE.
FALSE!
400
TRUE OR FALSE: CAN DAISIES GROW IN DIFFERENT TYPES OF SOIL.
THIS IS A TESTABLE QUESTION
TRUE BECAUSE IT CAN BE TESTED
400
WHAT IS THE DEPENDENT VARIABLE IN AN EXPERIMENT?
WHAT IS THE CONSTANT OR CONTROLLED VARIABLE?
DEPENDENT VARIABLE IS THE FACTOR OR CONDITION THAT MAY BE AFFECTED BY THE INDEPENDENT VARIABLE.
THE CONSTANT OR CONTROLLED VARIABLE IS ALL THE FACTORS THAT ARE KEPT THE SAME.
400
INFERENCES ARE NOT WILD GUESSES BUT ARE _________
EXPLANATIONS FOR WHAT WE OBSERVE.
LOGICAL
400
WHY IS IT HELPFUL TO CONDUCT AN EXPERIMENT SEVERAL TIMES BEFORE DRAWING A CONCLUSION?
THE RESULTS WILL BE MORE ACCURATE
500
IDENTIFY THE TESTABLE QUESTION:
ANDRE AND MARIE LOVE POPCORN, BUT THEY DON'T HAVE MUCH MONEY TO SPEND. THEY WANT TO DECIDE IF MORE EXPENSIVE BRANDS OF POPCORN POP MORE KERNELS THAN OTHERS.
DO MORE EXPENSIVE BRANDS OF POPCORN POP MORE KERNELS THAN LESS EXPENSIVE BRANDS?
500
EXPLAIN WHY IT IS IMPORTANT TO ONLY CHANGE ONE VARIABLE AT A TIME.
SO YOU CAN BE SURE IT IS THE ONE THING THAT CAUSED THE RESULTS
500
IN A GOOD HYPOTHESIS, THE PREDICTION EXPLAINS HOW THE ____________________ VARIABLE WILL AFFECT THE __________________ DEPENDENT VARIABLE.
INDEPENDENT AND DEPENDANT
500
WHAT ARE TWO VERY COMMON WAYS THAT SCIENTISTS RECORD INFORMATION?
CHARTS, TABLES OR GRAPHS
500
WHY IS IT VERY IMPORTANT TO FOR SCIENTISTS TO SHARE CONCLUSIONS WITH OTHER SCIENTISTS?
