Soil Test Kit Instruction Sheet – A Curriculum Resource for Chemistry

The two-page instruction sheet that accompanies the Luster Leaf Rapitest© Soil Test Kit could be a useful curriculum resource for chemistry teachers for generating discussion about the key aspects of the content or for helping students practice close reading skills. This article will briefly describe the contents of the instruction sheet and suggest possible uses in the general chemistry curriculum by posing questions for students to answer or consider. 

Balancing Equations, Candy and an Evolving Activity

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.

Balancing Equations with Molecular Models

I am a very firm believer that the world of physical science can be visualized and is an excellent medium for teaching students to model and to picture what happens at the molecular level. The first topic we decided to explore was balancing chemical equations. This seems like such a simple topic to chemistry teachers but I have found that it can be quite challenging for many of my inner city students. The first thing they ask me for is a list of rules that they can follow. We can discuss the problems of algorithmic teaching in a later post! For the time being let’s talk about how to get students to understand why they need to balance equations and discuss what we can call “Conservation of Atoms”.
