Scientific Method Review

Are you ready for your test?

slide2
Q1
  • The step of the Scientific Method that is in a question format.
  • Answer: PROBLEM
slide3
Q2
  • A testable statement in the scientific method
  • Answer: HYPOTHESIS
slide4
Q3
  • The part of the scientific method that allows us to test the hypothesis.
  • Answer: EXPERIMENT
slide5
Q4
  • The group that the experiment is performed on.
  • Answer: EXPERIMENTAL GROUP
slide6
Q5
  • The group that the results are compared to and it receives no experimental treatment.
  • Answer: CONTROL GROUP
slide7
Q6
  • The variable changed by the scientist and it is what the scientist is testing in the experiment.
  • Answer: INDEPENDENT VARIABLE
slide8
Q7
  • Data used to make graphs, gained from counts or measurements and it is numerical.
  • Answer: QUANTITATIVE DATA
slide9
Q8
  • The variable that is measured or observed throughout the experiment.
  • Answer: DEPENDENT VARIABLE
slide10
Q9
  • The axis where the independent variable is placed.
  • Answer: X-AXIS
slide11
Q10
  • A concise statement above the graph that tells the reader what the graph is about.
  • Answer: TITLE
slide12
Q11
  • Should include all data points and climb in intervals such as multiples of 2, 5, 10, etc.
  • Answer: SCALE
slide13
Q12
  • The axis where the dependent variable is located.
  • Answer: Y-AXIS
slide14
Q13
  • A short description concerning the graph’s data.
  • Answer: LEGEND
slide15
Q14
  • The type of graph that best shows the relationship between two variables. The data is continuous.
  • Answer: LINE GRAPH
slide16
Q15
  • Type of graph that has labels rather than numbers on the x-axis. The data is not continuous.
  • Answer: BAR GRAPH
slide17
Q16
  • A graphs that shows the data as a percentage in relation to the total data.
  • Answer: CIRCLE GRAPH
slide18
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
slide19
Q18
  • This section of the lab report contains the independent variable, dependent variable, and controls.
  • Answer: EXPERIMENTAL DESIGN
slide20
Q19
  • The section of the lab report explains any mistakes you made during the lab.
  • Answer: SOURCES OF ERROR
slide21
Q20
  • This section of the lab report tells what happened in the lab and why.
  • Answer: ANALYSIS
slide22
Q21
  • The section of the lab report where you reject or accept your hypothesis.
  • Answer: CONCLUSION
slide23
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?
slide24
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
slide25
Q24
  • What is the control group in the weed killer experiment?
  • Answer: MR. ORANGE’S LAWN WITH NOTHING APPLIED
slide26
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
slide27
Q26
  • What is the independent variable in the weed killer experiment?
  • Answer: THE WEED KILLER BRAND X OR T
slide28
Q27
  • What is the dependent variable in the weed killer experiment?
  • Answer: THE AMOUNT OF WEED KILLER IN EACH LAWN
slide29
Q28
  • Is the weed killer experiment done in a controlled environment?
  • Answer: NO, BECAUSE IT IS OUTSIDE, NOT IN A LAB
slide30
Q29
  • The common steps that biologists and other scientists use to gather information and answer questions.
  • Answer: SCIENTIFIC METHOD
slide31
Q30
  • Jack and Jill collected the following data: green, strong, dark, and many ears of corn. What kind of data is this?
  • Answer: QUALITATIVE
slide32
Q31

slide33
Q32
  • What is the correct format for a hypothesis?
  • If, then (and a prediction)
slide34
Q33

  • Type of potato
slide35
Q34
  • If students prefer French fries to tater tots then they will eat 10% more each lunch.

slide57
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.
slide58
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.
slide59
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.
slide60
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!”
slide61
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.”
slide62
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.”
