Using Periodic Properties to Group Students for an Activity

Thu, 03/19/2015 - 07:38 -- Lowell Thomson

Today in my IB Chemistry class we were reviewing the Born-Haber cycle. This has proven particularly challenging in the past so I wanted to try something a bit different and have the students review in groups. The task for each group of students was to create a visual Born-Haber cycle for potassium oxide - ignoring the math and calculations but instead focusing on each process within the cycle. I'd like to share how I grouped students using periodic properties.

The Model So Far...

Thu, 03/12/2015 - 21:28 -- Erica Posthuma-Adams

I started thinking about how integral the storytelling was to the curricular choices I made in my classroom.  I realized that I had shared some of my experiences as a Modeler and a few of the activities we use in our classrooms, but I have never described the order of topics. So, this blog is titled “The Model So Far…” I hope it gives you an idea of the journey we take each year as the students uncover evidence and construct models along the way.

Why do we have to do chemical equations and calculations?

(A look at workplace exposure limits found in MSDS sheets)

There is useful information in section 8 of a (Material) Safety Data Sheet (MSDS) that teachers can use and shows how a knowledge of chemical equations and calculations helps protect the health of their students and themselves and helps to assure their employers and safety officers that teachers and lecturers are responsible and professional users of chemicals.
