high school chemistry
As chemistry teachers, there are many ways we can relate our subject to the world around us. Linking with an effort to increase literacy at my school, I've started reading a non-fiction book with one of my chemistry classes titled, “The Case of the Frozen Addicts: Working at the Edge of the Mysteries of the Human Brain."
The nail bottle demonstration is one that many of us have conducted in our classes. To perform this demonstration, 2 – 3 mL of ethanol is placed into a plastic bottle that has two nails punctured into opposite sides of the bottle. After stoppering the bottle, a Tesla coil is touched to one of the nails. A spark jumps from one nail to the other, which initiates the combustion of vaporized ethanol inside the bottle. We recently filmed this reaction with our high speed video camera.
My students and I intend to use a high-speed camera to film a variety of chemistry experiments in slow motion. The first reaction we have decided to film is the “Whoosh Bottle”. You can read more about this particular experiment i
I am excited with my student's response to offering an ACS ChemClub at our high school! ACS does a great job of providing materials and ideas for meetings.
This year one my goals is to use this space to talk specifically with various teachers about how they use inquiry in their chemistry classrooms. My four questions are:
As I maneuver through the school year, a certain rhythm develops. The start of the year brings the excitement of new classes and new students. I'm often trying new things in the fall as I've reflected on the previous year's teaching over the summer. The energy level is certainly much higher at this time than almost any other.
