Ice Cores, Stable Isotopes, Climate Change, and Chemistry

Thomas Cox | Thu, 06/11/2020 - 18:38

Ice core science is truly cross-disciplinary as it draws extensively from chemistry, geophysics, geology, engineering, oceanography, microbiology, statistics, a deep understanding of historical events, atmospheric science, and climate science. And general chemistry topics include solubility, concentration, phase diagrams and changes, and stable isotopes in addition to many others. Let's take a first look at how ice core science can be used in teaching chemistry.

Evaluating students' written work

ACCT Admin | Wed, 06/10/2020 - 13:48

Formative assessment is an important component of teaching as it enables teachers to enhance student learning. The written work that students produce on formative assessment tasks can be used to uncover student thinking and inform the decisions teachers make on how to support individual student learning.

With the end of school upon us and the possibility of remote instruction in the fall, here are some techniques  to address four NGSS science and engineering practices; Planning and Carrying out Investigations, Asking Questions and Defining Problems, Developing and Using Models, Analyzing and Interpreting Data.

 

Metabolic Marvels of Bear Hibernation- Part 4

Scott Donnelly | Tue, 05/19/2020 - 20:35

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...

Mt. St. Helens 40 Years Later: Getting More from Soda Volcano Demonstrations

Dean Campbell | Sun, 05/17/2020 - 18:00

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.
