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.
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.
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.
This past summer, I took part in an online professional development offered by Beyond Benign. 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.
NGSS and the new AP chemistry curriculum have included modelling in the chemistry curriculum, so it is imperative that we have access to good conceptual questions surrounding modelling. I am in the midst of researching the best sources of these types of questions and resources that will help teachers to design their own. If you have any suggestions, please post them here.
