 In this lesson, students are offered a variety of alternative versions of the periodic table. Students will identify trends that are consistent from one table to the next in order to understand why the tables they are working with and Mendeleev's version are organized in the manner that they are. This lesson was designed to fit the NGSS performance expectation HS-PS 1.1 but can be used for any first year chemistry course or modified at your discretion.

One reason so many students find chemistry difficult is the abstract nature of the concepts. Research based on the constructivist model of learning has shown that as an educator teaches, the learner makes meaning of the content by drawing from their background knowledge, attitude, abilities and everyday experience and this often results in a different construct than that of the teacher.

The post-Thanksgiving excessive calorie-consumption 'blues' have arrived. How is it possible to eat so much? For a bear, it's easy. Easy as pie. Bears are champion eaters, spending about half the year eating non-stop in preparation for winter's foodless landscape. How can this calorie consumption observation about the bear world be used to teach certain chemistry concepts routinely covered? This post includes discussion and two classroom activities about the following common general chemistry topics/concepts- thermochemistry, unit conversions, and interpretation of numerical data. Enjoy...

The flipped classroom of today looks vastly different from its initial form. Originally, class time was primarily used to complete homework assignments; however, more effective active learning practices tend to dominate class time in modern applications of the model. Although the flipped classroom has improved over the years, several challenges persist.

Millions of years of evolution has endowed brown (Ursus arctos) and black (Ursus americanus) bears with the enviable metabolic capacity to starve themselves for a long period of time and still survive. Truly, bears are chemist extraordinaires and their hibernation chemistry overall is arguably without equal in the mammalian world. Let's take an introductory look at what's going on.
