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).

As a secondary science teacher, I have contact with my students everyday. Making relationships and learning about all of my students is key to letting them know that I am invested in their success.

The American Chemical Society is offering a new service in hopes of making science more accessible to the public. Each week they issue a short collection of science articles, written in an interesting and engaging style, that you might use with your students to help them make connections between the curriculum and their own lives. The service is called Discoveries!, and it is free.

As teachers, we all know that our job extends far beyond the content we are required to deliver. We are educators, mentors, coaches, parents and more. It is important for us to find ways to wear all of these hats without burning out. I have learned many great strategies that certainly helped re-energize me as a teacher but there was one strategy in particular that I could not get out of my head.

I first learned about argument driven inquiry through a post written by Ben Meacham. I was interested in both the stoichiometry  lab and the way that it was presented to the students through Argument Driven Inquiry. This lead me to the Argument Driven Inquiry (ADI) website. The website provided many resources.

Inspired by Ben Meacham's post on stoichiometry, I looked to modify the lab sequence for my IB Chemistry class for our unit on stoichiometry. I will describe my experience modifying a typical empirical formula lab, along with using a modified version of the lab Ben shared.
