Welcome to the JCE Chemical Education Xchange (ChemEd X)! We hope to strengthen the community of chemistry educators by providing learning resources and forums for discussion and collaboration right here at this site. Take a look, and join in.
I get excited when I see the outside temperature drop below 0°F (-18°C). This is not because I enjoy cold weather. It is because when the outside temperature gets this cold, I can conduct a particular experiment that I think is quite beautiful. Check out the video.
In my grad program one of our discussions concerned how to teach science the way science is actually done. This seems to be one of the core ideas in the Next Generation Science Standards. The standards want to encourage students to think more like scientists and engineers as opposed to students seeking an A. Please share your thoughts!
My ChemClub students came to my room for a holiday celebration today. We made a batch of sea foam candy, an Elephant Toothpaste Christmas Tree, and marbled gift tags.
Recent ChemEd X posts about Expo neon markers led Tom Kuntzleman to create a video showing how he uses these markers to teach fluorescence and chemiluminescence.
As the trimester comes to an end, I have the chance to reflect with my chemistry students and ask them about course likes and dislikes. A major "like" that came out was the use of the Expo brand neon markers. I had heard about their use from Brian Bennett @bennettscience and how well they show up on the black lab tables.
One of over 100 activities in the collection, JCE Classroom Activity #92 describes how to test for the presence of iodide in iodized salt using only water, iodized salt, 3% hydrogen peroxide, vinegar and liquid laundry starch.
