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.
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.
I am a safety conscience science teacher. I am embarrassed about some of the things that I did in my classes early in my career that I did not realize were unsafe. I saw the demonstrations and activities done at professional development venues and assumed that if my mentors were using the activity, it was safe.
