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.

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.

This past summer, I took part in an online professional development offered by . According to the Web site, “Beyond Benign was created by Dr. John Warner, a founder of the field of Green Chemistry, to provide an approach and means for scientists, particularly those involved in green chemistry and sustainable science, to reach out to the public.” I learned a great deal from the training. I was exposed to many resources that I did not know existed. I found lessons that I can easily incorporate into my curriculum that make a connection between the student and the chemistry content. Nothing is more powerful in a chemistry classroom than when a student can identify how the course content affects their everyday life and their future.

We are encouraged to use modelling these days and I have some activities to share along with some videos that might help you in the process.

I used JCE Classroom Activity #111 in my chemistry classes today. (Subscription to JCE required.) What a great way to help students make the connection between number of ions present, the charges of the ions and the neutral compound formula.

Halloween is a great time of year to do experiments with fluorescence. Check out the video in which we experiment with some fluorescent yarn.

I was excited to recently come across a new free app for the iPad entitled goREACT by the Museum of Science and Industry, Chicago.
