Polar Chains and Webs
Pretend someone asks you where the Arctic and Antarctica are located on a globe or map and asks you what animals live at each of these Polar Regions. Next they want to know what these animals do and what they eat. “What animals do polar bears hunt? What do penguins eat?” you are asked. You then explain the food chain of either penguins or polar bears and go on to discuss the food web. During this discussion you explain the similarities and differences of the Arctic and Antarctica.
· Model supplies (individually determined by each team)
Your team will use your findings to make a “Similarities-Differences” list of the animal life in the Arctic and Antarctic. Then you will make a model of a food chain for either polar bears or penguins. You will use poster paper and markers to design a food web for your polar bear or penguin. Your team will use your model and poster to present your findings to the class.
Discussions Questions/Extensions ......
How are the food chains and webs similar in the Arctic and Antarctic? Why? How are they different? Explain why?
Elaborate on the geographic locations of polar bears and penguins how it addresses their survival. Describe their food chains and webs and explain how their geographic locations support them. How might global warming impact these chains and webs?
