The national ACS James Bryant Conant award was established in 1965 to encourage and recognize outstanding high school chemistry teachers. Candidates are chosen based upon evidence of high quality teaching, ability to challenge and inspire, extracurricular activities that support their work and pursuit of continued improvement of their role as an educator.
Chemistry teachers are always looking for new ideas to reach students. Social media is a new frontier to reach students AND collaborate with other chemistry teachers around the world 24/7. I hesitated to join Twitter because it seemed like "just one more thing to add to my plate". I did finally log on and created an account.
The US Chemical Safety Board is an independent federal agency in Washington DC. They investigate industrial accidents. They just released a video of a young woman speaking about a high school chemistry class accident she was a victim of.
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.
Do you know where the term “isotope” comes from? The term was coined about 100 years ago.
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. Watch the video for an added twist to the activity.
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.
