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.
The mission of APTeach is to create a collaborative community where teachers can share ideas about student miconceptions, pedagogy, improving student understanding, and implementing best practices for teaching chemistry.
Sometimes, your Professional Learning Community is not at your school, but rather with educators from around the world.
Chemistry Education in Times of Disruption
