Here are photographs of the display. The students did an outstanding job in making their thinking and learning visible.
Our hunting results in fewer polar bears > Fossil fuel pollution causes trapped greenhouse gases > Trapped greenhouse gases speed up global warming
Global warming causes the ice to melt > Less time for hunting seals means lower weight of bears > Lower weight of female bears means smaller and fewer cubs
Smaller cubs have a hard time surviving the Arctic cold > Fewer surviving cubs means less adult bears > Less adult bears means fewer baby bears > Fewer baby bears means less adult bears > Eventually no more polar bears in the wild
