Bio: Hello and thanks for visiting. My name is Bill Brown. I have been a high school chemistry teacher in New York State since 2003. As a high school chemistry teacher, I love to present demonstrations that reflect the concepts that I teach. I have collected many books of demonstrations. They vary from books on how to make concoctions with kids up to university level demonstration books. Finding demonstrations in these books that are simple and straightforward and pertain to the concepts that I teach in high school chemistry is quite arduous. Finding demonstrations that fit this criteria and actually work is more difficult still. The goal of this blog is to present some demonstrations I currently use in my classroom and to create a dialogue that will help all of us improve in our ability to teach chemistry. I will try to present each of the demos in such a way that you can download a .pdf version that would be worthy of printing and keeping in a binder so that you can create a demonstration book of your own. Thanks for reading and sharing your ideas with me.
