This video resource explores the impact of climate change on polar bear populations and their Arctic habitat. It connects to our lesson on rates by examining the declining rate of sea ice formation and how this affects polar bear survival rates. Students can analyze the changing ratios between ice coverage and open water over time, as well as calculate rates of population decline in relation to habitat loss. This provides a real-world application of ratio and rate concepts while raising awareness about environmental issues.
