Cautious Chemist Corner #1
// Monday, July 14, 2014 • Deanna Cullen
I was at a chemistry teacher workshop recently and we participated in a common Hess’s Law laboratory. Part of the procedure required us to measure about 2 grams of solid NaOH and add it to 100 mL of 0.5 M HCl. We also added 50 mL of 1 M NaOH solution to 50 mL of 0.5 M HCl solution. We then compared the energy change of both containers.

A Modeling Approach to Energy Storage and Transfer
// Saturday, May 3, 2014 • E Posthuma
In a previous blog post I described some problems I encountered when beginning my instruction on energy this year.  From the misconceptions fostered by the biology textbooks using the phrase “high-energy phosphate bond” to idea that energy comes in different forms, the Modeling community recognizes the challenges of teaching the energy concept and has developed a way of talking about energy designed to help students construct a consistent and cohesive model.
