Opportunities For Chemistry Modeling Training

Tue, 02/24/2015 - 18:02 -- Deanna Cullen
modeling training

The Modeling™ curriculum emphasizes modeling, collecting evidence, scientific discourse and development of conceptual understanding. All of these can be linked to AP and NGSS standards. If you are looking to make improvements in your curriculum and gain some impressive strategies, consider enrolling in a workshop this summer. There are many workshops scheduled around the country during the summer. A full curriculum and support materials are provided.

Demonstrating the Colors of Transition Metal Complex Ions

Tue, 02/24/2015 - 08:15 -- Lowell Thomson

Just the other day within my IB Chemistry HL classes, we were discussing the color of transition metal complex ions in solution. It's a bit imperfect, because they are not yet dissolved, but I set up a number of metal chloride salts in order to help students see the pattern. They are arranged according to the position of the metal in the periodic table. It ends up being quite obvious to the students that the only metal salts with color are in the d-block. I'm now in the process of ordering more chloride salts so I can complete the pattern even more the next time I teach this topic.

I teach AP chemistry and general chemistry at Hudsonville High School in the Grand Rapids area.  I applied for the HACH grant last spring and was very excited when I was one of the recipients that was accepted.  The process of applying is very easy.  Your request obviously has to be well thought out.

A Post-Inquiry Activity: A Tiered Significant Figures Lesson

Historically, my students report significant figures as one of the most confusing concepts in honors chemistry. My recent blog post described the process of transforming my introduction into an inquiry activity. I’ve also re-worked my practice activities to be more directed to specific student needs, more focused on spending time with small groups, and more dedicated to active learning. This four step tiered plan works for me.

A “Buzzing” Introduction to Significant Figures

Education “buzz words” can be meaningless jargon, or they can challenge us to consider new approaches to teaching and learning. Don’t let the jargon be a buzz kill!

“Significant figures are so confusing,” says my former student, who is currently taking AP Chemistry. My PowerPoint lecture with lab to follow didn’t work. Convicted, I wrestled with transforming my tired lesson. I embraced the buzz words. Let’s look at a significant figures lesson that changed my compliant, quiet learners to ENGAGED COLLABORATORS.

How I Obtained Lab Equipment - Hach Grant

Thu, 02/05/2015 - 10:22 -- Ryan Schoenborn

Chemistry teachers face many challenges. One of those challenges is providing our students with the equipment and resources they need to be successful. Many teachers find themselves in schools that cannot afford to properly outfit their chemistry courses. That is exactly the situation I found myself in as a new teacher.

Chemical Mystery #4: The Case of the Misbehaving Balloon

Tue, 02/03/2015 - 11:19 -- Tom Kuntzleman

Conducting experiments with liquid nitrogen experiments is a sure-fire way to energize many chemistry lessons. Unfortunately, getting access to liquid nitrogen can be a bit difficult. I happen to purchase liquid nitrogen from Airgas; you might be able to find a branch near you here.
