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.
As this is my first blog post, I’d like to introduce myself to the ChemEdX community. I currently teach Chemistry I, Introduction to Organic and Biochemistry, and AP Chemistry at The University High School of Indiana. I use the Chemistry Modeling Curriculum in my classroom
I expect that most high school chemistry teachers assign some type of laboratory related to types of chemical reactions including synthesis, decomposition, single replacement and double replacement reactions. I have used several published versions, but I am sharing my modifications.
20 minutes prep, 40 minutes laboratory, 15-20 minutes discussion
It has happened again. We just published a “Lab Accidents” blog with a link to the US Chemical Safety Board’s video entitled “After the Rainbow” published December 10, 2013. Less than a month later, a young boy has experienced the same nightmare scenario as the one described in the video.
