### Scientific Method Review

Q1
• The step of the Scientific Method that is in a question format.
Q2
• A testable statement in the scientific method
Q3
• The part of the scientific method that allows us to test the hypothesis.
Q4
• The group that the experiment is performed on.
Q5
• The group that the results are compared to and it receives no experimental treatment.
Q6
• The variable changed by the scientist and it is what the scientist is testing in the experiment.
Q7
• Data used to make graphs, gained from counts or measurements and it is numerical.
Q8
• The variable that is measured or observed throughout the experiment.
Q9
• The axis where the independent variable is placed.
Q10
• A concise statement above the graph that tells the reader what the graph is about.
Q11
• Should include all data points and climb in intervals such as multiples of 2, 5, 10, etc.
Q12
• The axis where the dependent variable is located.
Q13
• A short description concerning the graph’s data.
Q14
• The type of graph that best shows the relationship between two variables. The data is continuous.
Q15
• Type of graph that has labels rather than numbers on the x-axis. The data is not continuous.
Q16
• A graphs that shows the data as a percentage in relation to the total data.
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.
Q18
• This section of the lab report contains the independent variable, dependent variable, and controls.
Q19
• The section of the lab report explains any mistakes you made during the lab.
Q20
• This section of the lab report tells what happened in the lab and why.
Q21
• The section of the lab report where you reject or accept your hypothesis.
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.
Q30
• Jack and Jill collected the following data: green, strong, dark, and many ears of corn. What kind of data is this?
Q31
• Name the Safety Symbol
Q32
• What is the correct format for a hypothesis?
• If, then (and a prediction)
Q33
• If students prefer French fries to tater tots then they will eat 10% more each lunch. What is the independent variable?
• 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
• What units does a triple beam balance use to measure mass?
• grams
Q36
• What units is temperature measured in for science?
• Degrees Celsius
Q37
• What is unit of measurement for volume?
• mL
Q38
• What are the best units to measure diameter of a penny?
• mm
Q39
• What is the purpose of a graduated cylinder?
• Measure/transfer the volume of a liquid
Q40
• What is this a picture of?
• Erlenmeyer
Q41
• What is this a picture of?
• beaker
Q42
• What does this measure?
• mass
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
Q48
• Is it okay to taste a sample of table sugar used in a lab experiment?
• no
Q49
• When is it okay to work alone in the lab?
• Never
Q50
• Where do you put broken glassware?
• In the properly labeled disposal designated for broken glass (Bob in Mrs. Gaines’ class)
Q51
• What should you do in the event of a chemical spill?
• 1st tell teacher
• Only if instructed, clean it up
Q52
• What should you do before the lab begins?
• Listen for special instructions
• Get equipment
Q53
• What should you do when the lab is over?
• Clean up
• Wash hands
Q54
• Why is horse-play unacceptable in the lab?
• Dangerous/unsafe for self and other students (someone could get hurt)
Q55
• How should you pick up a beaker of boiling liquid?
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 LUCK
• STUDY HARD!!
