Here is something to ponder as you think about your lab experiences this year: I have been using an excellent inquiry lab for the past few years. I think it does a fabulous job guiding the students through the amazing (yet often dull to students) world of specific heat equations and learning about calorimetry. However, this semester, I returned to the old, traditional calorimetry lab. I wan
Will you be attending BCCE 2014? There is still time to register! This is one of the best opportunities for high school chemistry teacher professional development. Grand Valley State University BCCE organizers have worked to make this year’s BCCE an affordable and valuable experience for high school level teachers. High school teachers may register at the reduced rate of $210 ($350 for regular attendees). If you are attending, I hope you will consider attending our ChemEd X Workshop. We will provide training to those interested in contributing their ideas with our community of educators. See the workshop abstract below. I hope to see you in August!
I was looking for a new demonstration to initiate a discussion about polarity and related properties to use as part of an exam review. I found a video at ChemEd X (this is part of a ChemEd X subscription). It is entitled “Floating Squares – Hexane and Water” (see note below). I have placed both solutions together before, but I had not added the squares. The demonstration fulfilled my needs. I could have used the original video and muted it if I had not had hexane to demonstrate with.
“It sort of started to look kind of like a very pale blue.”
A friend who teaches at the middle school level told me about a science experiment he’d done with his students. The procedure suggested to students that a particular solution would turn blue, but also asked them to write down what they saw happen. The thing was, it wasn’t actually designed to turn blue.
I've mentioned previously that my current grade 10 class is reading "The Case of the Frozen Addicts" together. As my students starting writing their blogs to respond to the reading, I saw quite a few questions that I couldn't answer. But I didn't want to leave the questions there with no response, so I went to Twitter to find scientists to join my class as a guest speaker.
Last year I wrote about a very simple experiment can be done using water, a plate and M&M’s candies. The experiment can be seen in the video below:
I have been a member of the American Association for Physics Teachers (AAPT) since I began teaching in 2010. Each summer I attend the AAPT national meeting and give a short talk or poster presentation about some form of research that I conducted in my classroom that year.
