Yоur grоup designed аnd cоmpleted аn experiment thаt quantified the number of types of bacteria in high-contact areas such as the men's bathroom door handle, elevator button, and the drinking fountain button, and the lab bench sanitized with 75% alcohol. Your group chose these areas based on your hypothesis: High-contact areas will have lots of bacterial types. You swabbed these areas, and applied the swab for each area to assigned quadrants on a TSA plate. Your group predicted that the number of bacterial types for each area from highest to lowest: men's bathroom door handle, drinking fountain button, elevator button, sanitized lab bench (0 bacterial colonies). After a week, your group scored and quantified the bacterial types in your TSA plate. Your data shows the number of bacterial types from highest to lowest: water fountain button (8 colony types), sanitized lab bench (5 colony types), elevator button (4 colony types), men's bathroom door (3 colony types). You have been assigned to write the Discussion section of the lab report. Discuss why you got the results you got. Identify the following and why you identified them as such: the independent variable, dependent variable, constant variables in your experiment, negative control sample, experimental samples. Based on your data, did your experiment work, or do you have to repeat it? Explain your answer. What is the role of the negative control in your experiment. Based on the results of your experiment, does your data support your hypothesis? Explain why the sanitized lab bench has 5 colony types and the men's bathroom door handle has the lowest number of colony types.
