The new AP Chemistry Course and Exam Description (CED) has been released and in effect for a few months now. Several teachers have asked me “Will you be changing your sequence to match the CED?”.

I usually start of the school year with a measuring activity. This year, I used Tom Kuntzleman's Mentos and Diet Coke experiment and had students use the data to do some graphing and analysis. This was a nice lead into our gas unit. I also made my own syphon coffee maker to demonstrate for my students.

Many teachers assess engagement with video lectures by inspecting students’ notes at the start of class. However, notetaking doesn’t necessarily prove the comprehension of the material.

Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"

I have been working on a cool research project for over a year now and I had to learn to properly collect and analyze a lot of data. I would like to introduce a few of the basic techniques I learned and you perhaps can use to compare data by using software such as Microsoft Excel or Google Sheets.

I had the opportunity to develop an advanced chemical lab design course for a small group of ambitious students. I have outlined the resources I used and how I pulled the course together,

This simple idea can help students learn the importance of honest self-reflection and foster meaningful conversation between the student and teacher.

I just finished my first week of school, like many teachers in the Midwest. I work hard to get my Honors Chemistry students in a lab setting as soon as possible. It is difficult to find a perfect lab to do on the first or second day of school. In my mind, the ideal first chemistry lab would require no prior chemistry knowledge, involve interesting chemistry, address an NGSS standard, be relatively safe, not require expensive glassware or lab tools, and reinforce positive class norms. I have found engineering labs fit the bill! I don't know if I have found the "perfect" lab, but I have found something close I want to share!

It is back-to-school time! I started school on September 3rd so I am just getting back into my school “groove.”  On August 1st, College Board released its new AP Classroom platform (myap.collegeboard.org). While exploring this new online resource, I couldn’t help but reflect on how I teach AP Chemistry and what changes I will make in light of AP Classroom to ensure this year will be a great one!
