We all know how fundamental the mole concept is for stoichiometry. This year I brainstormed ways to really make it stick. I decided to do multiple mini-practicums, one for each learning target of the mole unit. I am sharing brief descriptions of the mini-practicums I did for each learning target.

With a Master's degree in geology, I have a deep and abiding love for rocks and minerals. The great thing about geology is, it's all about chemistry! I want to share one of my favorite links between geology and chemistry that my students think is pretty cool too.
For this coming school year, I would like to kick off every unit with a discrepant event, and then bring it back at the end of the unit for students to explain with their new model.
I spent the week learning about the field of chemistry education, being in awe of Notre Dame’s campus and most importantly, geeking out with some of the most amazing chemistry teachers you will ever meet.
When the idea of going deskless popped into my head last spring, it was in response to classroom management and safety issues that had been arising with increased class sizes, the addition of inclusion physical science 9 to my schedule and the adoption of a 1:1 Chromebook program.
Once you get into your teaching routine, there is not a lot of struggle. There are changes and challenges, but rarely do you encounter a situation that completely breaks your confidence or forces you entirely out of your comfort zone. I don’t think I fully appreciated the frustration, pain and inadequacy my students sometimes feel until today.
In the past five years I have wrestled with the questions, “what is the purpose of a final exam” and “how do I incorporate a final exam into my grading system.” At this point, I have found peace in answers to both of these questions and part of that relies on my students completing an electronic portfolio.
In my class, I use the illustration of a mountain to help students push through the challenges of chemistry. Stoichiometry is the top of chemistry mountain. As we progress through the year, I say things like “the mountain is getting steep here!” or “there is not a lot of oxygen up here!” or “I will carry you up chemistry mountain if I have to!” to keep students motivated. When students finally get to the top of chemistry mountain (mid quarter 3), the air is thin, they are tired and they are ready to base jump off the mountain (see illustration from a former student below).
