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.
In this blog post, I share how I use an article from Dr. Peter Atkins, "Chemistry's Core Ideas." My IB Chemistry students read the article early in our program - and then revisit the article numerous times throughout our two-year course. The Google Slide document my students use is included in the supporting information.
I have written about Atomsmith before, but the new updates are worth another mention.
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.
I was having difficulty with a student that was making poor choices in the lab. When I saw him making positive choices and acknowledged that, our relationship changed for the better.
