If you have never attended a BCCE, I offer some reasons to change that this summer. The conference will be in Notre Dame this summer. Please vote for the topic that you would like me to develop my presentation about.
I feel like every year I face the same old dilemma. It starts with an idea in mind of what and how something should be taught. This idea is fine until it is discovered that students this year are different than students last year. The idea is changed or “tweaked”. The process is feels similar to having to “reinvent” the wheel each year. This gets exhausting.
It was close to the end of the semester and we were covering gas laws. Students were stressed over the idea of finals, final projects due, tests before finals and the holidays. Since we were finishing up the topic and it was important to end with one last assessment and/or lab but the timing was not good and the stress level for everyone was at an all time high. A different course of action was needed.
Density Bottles can be used to teach a variety of chemical concepts such as density, solubility, and polarity. In this post it is shown that Density Bottles can also be used to differentiate between heterogeneous and homogeneous mixtures, and to explore light scattering.
Nomenclature is a tough topic. I tell students that we are living in the land of symbols while we study nomenclature. It is important but it is difficult to get them excited. I started fishing for resources. The American Association for Chemistry Teachers (AACT) has been a great resource to help me try new things.
Take a look at an old favorite, the brass penny activity. There are several variations of procedural steps to be found. The safest version uses either a low concentration of NaOH or a solution of zinc chloride.

There are many activities that can be used to cover the topics of percent composition, empirical and molecular formulas and hydrates. Percent composition of sugar in a piece of bubble gum is an easy activity to begin the unit with.
