A Better Way to Organize Laboratory Equipment

organizing laboratory equipment

I decided to take the time and to do some needed inventory.  I wanted to match equipment to its designated table.  Next, I wanted to make sure that each of my eight lab tables had the proper equipment needed to eliminate no more missing equipment.  Sure enough, as I began the inventory project, I had several tables missing equipment, so once everything was laid out and counted and organized then I had to make sure it was going to stay that way.  I had several rolls of colored tape and it was easy to then begin marking each of the pieces of equipment and glassware with tape. 

Using the ACS Exams in Your Classroom

Say the words standardized test to most educators and you will likely notice a minor gag reflex. While I completely sympathize with this reaction given the frequently labeled testing culture that’s been far too often forced upon us within the past 15 years, I think it is appropriate to take a step back and recognize the meaningful role a standardi

Erica Jacobsen shares highlights from the June 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.

Acid, Base, pH and Food Chemistry

Muffins

I try to examine activities an multiple levels. First on the list, I want to know if my students will be engaged and learn something. Second, how difficult is it for me as a teacher to actually pull it off? One of the most important questions...are the students learning chemistry or just having fun? This is the first year I have attempted the following activity.  tudents were engaged in the real world connection, they asked questions, it transitioned into some chemistry concepts and even some parents got involved. The activity involved acid, bases, pH and food.

Time required: 

An evening of baking (about an hour at home) and a day in class.

Reduction of Permanganate Ion by Acids in Rhubarb, Apples, and Candy

Apples

If rhubarb stem is placed in a solution of permanganate, the purple permanganate ion is reduced to the colorless Mn2+ ion. It is thought that the oxalic acid present in rhubarb causes this reduction. The investigations presented in this post provide evidence that this may not be the whole story...
