Page 12/18You may or may not have found support for your hypothesis. If you did not find support for yourhypothesis, you probably need to revise your hypothesis and do another experiment. However, even ifyou did find support for your hypothesis it is probably important to test whether the other variablemight also result in Simploid sickness. Repeat the experiment – if you started with herbicide, switch toparasites or vice versa. Again avoid looking at them together – this will make it much harder for you towrite your lab reportPage 13/18Here you should choose the opposite hypothesis from Question 8 above. Again avoid the combinationfor now.Page 14/1814.Answer to Q2.12To test my hypothesis about the cause of the Simploid sickness, I will vary the independent(treatment) variable(s)Herbicideandnothing alsoacross study plots. Plots in my control groupwill haveno herbicide15.Answer to Q 2.13. So that you can compare your results directly with your previous experiment,choose the same outcome here (e.g. if in Q2.7 you chose % Simploids sick, you should alsochoose this here)
16.What are the potentially confounding variables that you will hold constant in this secondexperiment?
17.In order to compare your results between experiments 1 and 2, what things should you makesure are the same in both?
18.Describe your experimental design including the number of simploids/plants in each plot andhow many plots were treated with herbicide/pesticide. When you click Check your Setup, youshould get positive feedback. If not, try again until you have a solid setup.
19.How is this experimental setup similar to your setup in the first experiment?How does it differ.the
21.What do your two experiments suggest is the cause of Simploid sickness.
Section 3: Graded questionsAnswer these questions.
