Lab Extension
At 82% progress is this lab simulation you are asked to create yourown experiment.
What observation or questions are you investigatingwith this experiment?
Write down your hypothesis.
Describe the experimental design .
Define the term control group. Which tube is thecontrol?
Define the term experimental/treatment group. Whichtube is the experimental/treatment group?
Define independent variable. In this experiment whatis the independent variable?
Define dependent variable. In this experiment what isthe dependent variable?
. Describe the data collected from the experiment.Include the temperatures you tested and how the growth curvesdiffered. Describe differences (if any) in the lag phase,exponential phase, stationary phase, and death phase. At this pointdo NOTinterpret the results.
Was your hypothesis supported or rejected?
Interpret the results to draw a conclusion. Thinkabout WHY you had the results you didand HOWthis relates to temperature as a limiting factorin bacterial growth.
