Scientific Method Review
Are you ready for your test?
Q1
The step of the Scientific Method that is in a question format.
Answer: PROBLEM
Q2
A testable statement in the scientific method
Answer: HYPOTHESIS
Q3
The part of the scientific method that allows us to test the hypothesis.
Answer: EXPERIMENT
Q4
The group that the experiment is performed on.
Answer: EXPERIMENTAL GROUP
Q5
The group that the results are compared to and it receives no experimental treatment.
Answer: CONTROL GROUP
Q6
The variable changed by the scientist and it is what the scientist is testing in the experiment.
Answer: INDEPENDENT VARIABLE
Q7
Data used to make graphs, gained from counts or measurements and it is numerical.
Answer: QUANTITATIVE DATA
Q8
The variable that is measured or observed throughout the experiment.
Answer: DEPENDENT VARIABLE
Q9
The axis where the independent variable is placed.
Answer: X-AXIS
Q10
A concise statement above the graph that tells the reader what the graph is about.
Answer: TITLE
Q11
Should include all data points and climb in intervals such as multiples of 2, 5, 10, etc.
Answer: SCALE
Q12
The axis where the dependent variable is located.
Answer: Y-AXIS
Q13
A short description concerning the graph’s data.
Answer: LEGEND
Q14
The type of graph that best shows the relationship between two variables. The data is continuous.
Answer: LINE GRAPH
Q15
Type of graph that has labels rather than numbers on the x-axis. The data is not continuous.
Answer: BAR GRAPH
Q16
A graphs that shows the data as a percentage in relation to the total data.
Answer: CIRCLE GRAPH
Q17
The part of a lab report contains the title of the experiment, your name, all of your lab partner’s names, experiment dates, class and hour.
Answer: TITLE/COVER PAGE
Q18
This section of the lab report contains the independent variable, dependent variable, and controls.
Answer: EXPERIMENTAL DESIGN
Q19
The section of the lab report explains any mistakes you made during the lab.
Answer: SOURCES OF ERROR
Q20
This section of the lab report tells what happened in the lab and why.
Answer: ANALYSIS
Q21
The section of the lab report where you reject or accept your hypothesis.
Answer: CONCLUSION
Q22
Mr. Orange, Mr. Blue, and Mrs. Purple all had weeds growing in their yards. Mr. Orange does nothing about his weeds. Mr. Blue applies weed killer X. Mrs. Purple applies weed killer T. What is a good problem for this scenario?
Answer: WHICH WEED KILLER IS GOING TO KILL THE MOST WEEDS?
Q22
Based on the weeds scenario, what is the hypothesis?
Answer: IF BRAND X WEED KILLER IS APPLIED TO A LAWN THEN IT WILL HAVE LESS WEEDS THAN A LAWN TREATED WITH BRAND T WEED KILLER
Q24
What is the control group in the weed killer experiment?
Answer: MR. ORANGE’S LAWN WITH NOTHING APPLIED
Q25
What is the experimental group in the weed killer experiment?
Answer: MR. BLUE’S LAWN & MRS. PURPLE’S LAWN BECAUSE THEY BOTH HAD SOME SORT OF WEED KILLER
Q26
What is the independent variable in the weed killer experiment?
Answer: THE WEED KILLER BRAND X OR T
Q27
What is the dependent variable in the weed killer experiment?
Answer: THE AMOUNT OF WEED KILLER IN EACH LAWN
Q28
Is the weed killer experiment done in a controlled environment?
Answer: NO, BECAUSE IT IS OUTSIDE, NOT IN A LAB
Q29
The common steps that biologists and other scientists use to gather information and answer questions.
Answer: SCIENTIFIC METHOD

Answer: QUALITATIVE
Q31 Name the Safety
Symbol
Q32
What is the correct format for a hypothesis?
If, then (and a prediction)
Q33

Type of potato
Q34
If students prefer French fries to tater tots then they will eat 10% more each lunch.
What is the dependant variable?
Amount consumed
Q35

Q43
What were the three safety precautions for the blue lab?
Eye safety (goggles) Clothing protection (aprons) Chemical (careful of spills)
Q44
In the Blue lab why did the liquid change to blue only when half the flask was full?
Air/oxygen
Q45
What were you trying to determine during the blue lab? (What was the problem?)
Are liquids A and B the same?
Q46
While conducting the blue lab why did you perform three trials for each flask in experiment 3?
More valid/reliable
Q47
Was the liquid in flask A the same as the liquid in flask B?
yes

Q56
Al Kane was mixing two chemicals in a beaker. He noticed that a greenish-yellow gas was bubbling out of the liquids. He had been told to make all observations that he could, so he held the beaker close to his nose and took a good whiff.
Q57
Sally Forth was told to make observations about some liquids. One of the liquids was supposed to be a base and therefore have a slippery feel. So she carefully dipped the end of her little finger into each liquid and rubbed her thumb on the wet skin.
Q58
Messy Slob was usually the slowest person in the lab. She did everything so carefully that she seldom finished all of the procedure before it was time to clean up. On this particular day, Messy was so worried about not being late to her next class that even though she knocked over a beaker of liquid, she just left it and raced out of the lab.
Q59
Notta Clue and his partner Spacey Cadet were going to do a lab in their science class. As usual, they were late to class and all of the other students were already in the lab. “What are we supposed to be doin’ ?” asked Notta. “I don’t know,” replied Spacey. “Let’s just do what everyone else is doing!”
Q60
“We took too much of these chemicals,” said Hal Ogen to his partner Nob Legas. “Take the beakers up to the counter and pour the powders back into the bottles.”
Q61
Bob really liked Sally and was really pleased she was in his class. “I’ll have a chance to talk to her and ask her out,” he thought. “But she won’t even talk to me if I wear these dorky safety glasses and apron.”
ANY QUESTIONS???
GOOD LUCKSTUDY HARD!!
