Welcome to Part 4 in a series of posts looking at the metabolic chemistry that allows a bear to opt to survive winter by not eating at all and by doing so increase its chances of dying from starvation. By the end of hibernation up to a third- and more for a pregnant bear- of a bear's pre-denning mass may have been devoured by the bear's metabolic and physiological needs. A remarkable animal. A remarkable study in biochemistry. Enjoy...

Living at the macroscopic level, it’s no surprise that understanding and effectively communicating chemistry concepts can often be a challenging endeavor. Attempting to rationalize our observations through particle-level interpretations requires us to think in less intuitive ways that often create a cognitive barrier for our students. And for good reason.
