Interactive Case Study for The Effects of Fungicides on Bumble Bee Colonies
This video case study explores whether fungicides play a role in the decline of bee populations.
Fungicides are applied to a variety of flowering plants to protect them from fungi, not insects. However, entomologist Shawn Steffan wondered whether fungicides might be harmful to bees, which are declining due to a number of factors. This video case study presents an experiment that Steffan conducted to investigate the possible consequences of fungicide applications on bee colonies.
This video incorporates embedded questions at automatic pause points, where students are asked to make predictions, construct explanations, and analyze data. After answering all the questions, students can view their answers in a “Report” that can be printed. They can also add further explanation to each answer in the Report if their thinking has changed. The video can also be shown without embedded questions using "Presentation Mode."
