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(link is external) 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.
When the outside temperature drops below 0°F (-18°C), the conditions tempt this experiment!
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, experimented with Elephant Toothpaste, 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(link is external) 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.
Every year, high school teachers across the country are asked to write college recommendations for their current and former students. With today’s competitive college culture, and an ever-growing list of teacher responsibilities—how can we be expected to write 10, sometimes more, original college recommendations each year for our students? As a teacher who was just introduced to all of this two years ago, I’ve spoken with college recruiters, researched how and what to include within a recommendation letter, consulted with guidance counselors (who see the range of recommendations, confidentially), and, most importantly, spoken with veteran teachers who write recommendation letters. After putting together the results of everything that I have learned, I have developed the following set of tips and advice. So, whether you are a pro at writing recommendation letters and are just looking to keep your letters fresh or you are a complete novice, as I was not too long ago, I hope that my advice will be helpful to you.
