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.

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 week I talked with Alice Putti who teaches Chemistry and AP Chem in West Michigan.  Below are her answers to our inquiry questions:

Q1:  How do you define inquiry? or What does inquiry look like to you?

I recently spoke with a chemist from industry that said that if she admits to being a chemist, it is a serious conversation ender. I can relate! I know many of you can to. My colleague, Greg Rushton, shared a similar sentiment in an article introducing himself to the JCE community.

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.
