Building Molar Mass

An advantage to teaching on the trimester schedule allows me the opportunity to teach the same course again roughly twelve weeks later. So after grading my 2nd trimester students’ Chemistry B final exams, I was able to evaluate certain topics that caused my students problems, reflect on my teaching, and then determine how I was going to better prepare my students in the 3rd trimester chemistry B class.

Opportunities For Chemistry Modeling Training

The Modeling™ curriculum emphasizes modeling, collecting evidence, scientific discourse and development of conceptual understanding. All of these can be linked to AP and NGSS standards. If you are looking to make improvements in your curriculum and gain some impressive strategies, consider enrolling in a workshop this summer. There are many workshops scheduled around the country during the summer. A full curriculum and support materials are provided.

Conceptual Chemistry Questions

The new AP Chemistry Curriculum and the NGSS both focus on developing deep conceptual understanding. In order to achieve this, teachers must identify the objectives they need to teach to and stockpile a good assortment of conceptual questions for formative and summative assessments to support those objectives.

Floating Squares

I was looking for a new demonstration to initiate a discussion about polarity and related properties to use as part of an exam review. I found a . It is entitled “” (see note below). I have placed both solutions together before, but I had not added the squares. The demonstration fulfilled my needs. I could have used the original video and muted it if I had not had hexane to demonstrate with.
