Scientific Method in Action www.biologycorner.com Example 1: Elmer thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Elmer counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks. Identify the: 1. Control Group :______________________________________________________ 2. Independent (Manipulated) Variable :_____________________________________ 3. Dependent (Responding) Variable :_______________________________________ 4. What should Elmer’s conclusion be? ____________________________________________________________________________________ 5. How could this experiment be improved?_________________________________________________ Example 2: Peter notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Peter decides to check this this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower. 6. What was the iniitial observation? ________________________________________________________ Identify the: 7. Control Group _________________________________________________ 8. Independent (Manipulated) Variable _________________________________________________ 9. Dependent (Responding) Variable ___________________________________________________ 10. What should Peter's conclusion be? _________________________________________________ Design an experiment to answer the experimental question. Experimental Question: Will crickets chirp more if the temperature is warmer? Hypothesis: Prediction: Design your experiment. Be specific. Give details. What kind of data will you collect? If your results do not support your hypothesis, what will you change? (your hypothesis?, the experiment?) How will you change it? Name____________________________________ Graphing Assignment Scientists and professionals in many other fields often communicate using graphs. Good graphs summarize lots of information in an easy- to-understand visual format. This allows the reader to quickly evaluate the data. The graph below is from the Center for Disease Control (CDC) and it describes the transmission of zika, dengue, and chikungunya viruses in Puerto Rico from November 2015 through April 2016. (Dirlikov et al) Cases of zika virus, dengue virus, and chikungunya virus in Puerto Rico. Guidelines to Drawing a Good Graph: • • • • Title – include a descriptive title that contains enough information to understand the graph Label your axes – label both the X and Y axes and include units if necessary Legends – use a legend to help readers understand the graph (different colors, symbols) Make use of space – don’t crunch your graph into a little corner, it should take up the entire space Types of Graphs • Scatterplot – compares two variables o In the graph below, we can see that the longer eruptions of Old Faithful (a geyser in Yellowstone National Park) last, the longer the waiting time in between eruptions. • Histogram – compares the frequency of different events. The histogram below shows that the heights of most black cherry trees are between 70 and 85 feet. It is showing the frequency or how often each height occurs. • Bar graph – compares groups. The graph below shows that student loan debt was lower at AIKC University and in Kentucky compared to the national student loan debt in 2015. Class Survey – Information attached. Last semester BIOL 105 students collected information on: 1.How many hours per week on average they work 2.How many hours per week on average they study 3.Distance from home to school (miles) 4.Height (inches) 5.Gender Use the data included at the end of the handout to answer the following questions. You may hand draw or use Excel to make your graphs. 1. Construct a scatterplot comparing the number of hours students spend studying and working. On the x-axis, put the hours working. On the y-axis, put the number of hours studying. 2.In one or two sentences, describe any trends conveyed by the scatterplot. Is work time related to study time in any way? 3.Construct a histogram depicting how far students live from school. (Hint: it might be helpful to group miles. For example, those that live 1-5 miles from school, those that live 6-10 miles from school, etc..) 4.In one or two sentences, describe any trends you see from the histogram. 5.In the histogram, what is the independent variable? The dependent variable? 6.Construct a bar graph comparing the average height of women in the class to the average height of men. The x-axis should represent gender and the y-axis should represent height. 7.In one or two sentences, describe any trends you see in your bar graph. 8. In the bar graph, what is the independent variable? The dependent variable? Data Student Hours worked per week Hours studying per week Travel Time to campus (miles) Height (inches) Gender 1 30 6 15 67 F 2 21 8 3 64 F 3 30 10 2.5 58.8 F 4 0 10 2.5 64 M 5 25 15 4.5 75 F 6 20 3 3 66 M 7 10 15 4 73 M 8 20 12 2 68 F 9 20 6 8 67 M 10 26 10 2 67 M 11 40 12 25 61 M 12 30 4 20 72 F 13 11 3 15 64 M 14 20 20 6 69 M 15 0 15 15 68 F 16 18 1 10 70 M 17 20 36 2 63 F 18 30 3.5 1 65 F 19 0 5 1 65 F 20 10 2 1 67 M 21 30 3 4.5 66 F 22 0 10 10 60 F 23 5 4 5 66 F 24 0 40 10 62 F ...
