Conducting experiments with liquid nitrogen experiments is a sure-fire way to energize many chemistry lessons. Unfortunately, getting access to liquid nitrogen can be a bit difficult. I happen to purchase liquid nitrogen from Airgas; you might be able to find a branch near you here.
At my school in Michigan, the second semester just started this week. And, since all chemistry classes (except for IB Chemistry) are semester courses, I have new students and different preps.
I love teaching chemistry! It is fun to express that interest by collecting t-shirts and other items when I attend professional development.
This is the time of year when I start looking ahead and planning my professional development for the new year. As a mom to two young boys I simply cannot attend all the conferences, workshops, or lectures I’d like to. I have to research my options and determine how each opportunity aligns with t
In my high school chemistry classes, I stress the use of units and the use of written chemical formulas to be represented properly. It is important to me that when a student expresses the formula of a chemical either in their data or in a balanced equation that they represent it correctly. With t
Wow! Night one of the semester we did the activity Change You Can Believe In. It was my second time facilitating, so I did a much better job of directing students when they asked questions and it went much faster than last semester. I did still, as expected, have students that were frustrated. One student asked me point blank what the difference between physical and chemical changes is.

The doldrums after the holiday were a perfect time for these pages with their promise of spring. Their arrival kicked off an evening of grand plans. Somewhere along the line, chemistry crept in.
