stoichiometry

Nina shares a stoichiometry lesson using UNO cards.

Stoichiometry often proves to be a challenging topic for high school chemistry students, primarily due to its abstract nature and the reliance on rote memorization for problem-solving techniques rather than a conceptual understanding.

The importance and difficulty of concepts of the electrolyte came home to me while I was helping a student. She was having difficulty with the idea of an electrolyte. Specifically, she 1) misapplied the maxim "Like dissolves like," and 2) could not distinguish between the terms "dissolve" and "dissociate". In my knowledgeable na

A case study is a guided inquiry activity that embeds problem-solving within a simulated real-world context. Case studies tend to be more challenging than traditional word problems because they are presented in a longer form, commonly as a story.

The first unit in my sequence for AP Chemistry covers stoichiometry and reactions. The new AP Chemistry Course and Exam Description has identified Learning Objectives which need to be taught and practiced to ensure students perform well on the AP Chemistry Exam.

There is a lab that is called something like “The Mole Rocket Lab” or  “Micro Rockets”. Some of you may be familiar with the lab, but I wanted to write this post to share it with teachers who may not be aware of it. 

In Chemical Mystery #14, neutralization reactions were used to cause some interesting color changes. See the two videos below:
