Students will be able to:
use the information from the video Changing Nature and classroom discussions to
-describe how humans interact with the environment and other species.
-determine how food chains and food webs are affected by other species.
Students watched a video, Changing Nature to determine how humankind may affects the environment around them and other living species. Some of the questions that should be answered from the video are:
1. Draw the food chain mentioned in the video.
2. What role does the bunch beetle play in the food chain?
3. What role does the cider poppy play in the food chain?
4. What caused the death of the bunch beetles?
5. How did the dominant species cause a change in the food chain? List the steps.
6. What role did the destruction of the bunch beetle’s habitat play in destroying the food chain?
7. What is the effect of spraying defoliant on all plants? What would ultimately happen to the food web because of this?
8. Earl makes the statement “After all, dinosaurs have been on this Earth for over 150 million years. And it’s not like we’re just going to disappear.” How does this foreshadow what we know happened to the dinosaurs? Could the destruction of the global food web be a probable cause in the extinction of any species?
