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...

Potential enhancements to soda-based demonstrations of volcanic eruptions are described. Depending on the specific demonstration setup, outgassing of carbonated sodas can represent low-viscosity lava flows or more violent production of pyroclastic materials. These simple demos can be used as stand-alone experiments or in concert with other activities.
