Shawn wants to determine which species of bacteria and fungi live with bees. In a few sentences, describe a method you might use to identify the microbes.
Shawn has a hypothesis that fungicides harm bee development. Using what you now know, describe an experiment to test Shawn’s hypothesis. Be sure your response includes what data should be collected and how you would collect it.
Shawn plotted the data in a bar graph with two bars: one representing the number of bees per colony in the control cages and the other representing the number of bees per colony in the cages exposed to the fungicide.
If the results support the hypothesis that fungicides harm bee development, what would you expect this bar graph to show? Describe the expected pattern in a few sentences.
Are the results consistent with what you expected?
What do you conclude from this experiment? Write your conclusion in a few sentences.
Shawn explains that many studies have shown that directly spraying bees with fungicides doesn’t harm them. Are those results consistent with what Shawn has discovered? Explain your answer in a few sentences.
Shawn has made progress in understanding how fungicides may impact bee colonies, but there is still work to be done. Can you suggest additional research that you think would help us better understand how fungicides affect bees?
