Last year I came across a link on Twitter regarding an art installation by Roger Hiorns in England titled “Seizure.” Some of you may have seen it too – a condemned flat in London was essentially sealed off and filled with more than 75,000 L of supersaturated copper sulfate solution.
JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
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.
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.
The citation included on the plaque presented to the 2014 recipient of the James Bryant Conant Award in High School Chemistry Teaching reads “For her creativity, enthusiasm, and love of chemistry, inspiring students and teachers alike for over 35 years.”1 Kathy Kitzmann is all of that and more.
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.
The new AP Chemistry Curriculum and the NGSS both focus on developing deep conceptual understanding. In order to achieve this, teachers must identify the objectives they need to teach to and stockpile a good assortment of conceptual questions for formative and summative assessments to support those objectives.
Did any of you guess what was going on in Chemical Mystery #4: The Case of the Misbehaving Balloon? In this experiment, several balloons were placed in liquid nitrogen. Most of these balloons shrunk tr
One of the mantras in the article was “Blind people can’t do those things.” Blind people can’t walk without a cane. Blind people can’t climb trees. Blind people can’t go to a regular public school. Blind people can’t do various jobs. Blind people can’t pursue certain careers.
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.
