I have been interested in the adsorption properties of shells and other common materials. I decided to test the adsorption properties of almond shells towards methylene blue and I am sharing how it went here.
How do you demonstrate how a buffer system works? I did some brainstorming, devised a plan and it went well. This post is a description of what I did.
In our recently published letter in the Journal of Chemical Education,"Black Panther, Vibranium and the Periodic Table", we describe how the movie, Black Panther, provides a unique opportunity for students to think critically about the arrangement of the periodic table.
In the past five years I have wrestled with the questions, “what is the purpose of a final exam” and “how do I incorporate a final exam into my grading system.” At this point, I have found peace in answers to both of these questions and part of that relies on my students completing an electronic portfolio.
Imagine if you could start all over with a brand new classroom! What would you want or do in your dream room?
In this blog post, I would like to share a relatively simple demonstration you may use to introduce the concept of antioxidant along with its potential in everyday life.
This activity is designed to determine the concentration of Vitamin C (ascorbic acid) in a produce protector (in this case, Ball® Fruit Fresh) by an iodometric titration method.
Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.
Part of placing value on the process of learning means giving students multiple opportunities to demonstrate understanding. Reassessments are an inevitable part of the process. For many teachers, this presents a logistical problem. To help streamline the entire process, I would like to share a simple strategy that anyone can replicate in a short amount of time.
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
