Spotlight on AP Chemistry

Wed, 08/06/2014 - 09:14 -- Deanna Cullen
SPOTLIGHT ON AP CHEM

Greg Rushton and I presented in the George Hague Memorial AP/IB Chemistry Symposium at the 2014 BCCE conference in Michigan. We are excited to highlight the first SPECIAL ISSUE of the Journal of Education covering AP Chemistry. Given the new AP Curriculum, the time was right to put out a call for papers last year asking stake holders to weigh in on the topic. We are happy with the well rounded response and hope you will take a look at the issue. Most of the articles are already live on the JCE Web site. We are interested in your comments and also encourage suggestions of topics for future Special Issues that will be of interest specifically for the high school audience.

The Cautious Chemist Corner: Safety in the Classroom and Laboratory

Mon, 07/14/2014 - 21:22 -- Deanna Cullen
safety

Chemistry classroom accidents have been in the news too often recently. I hazard to suggest that there are smaller incidents that never make the news because there are luckily no serious injuries. We need to be vigilant in our safety concerns to protect our students and ourselves from any accidents and exposure to hazardous substances. We also need to be aware of theft concerns. Unfortunately, students may be looking for ingredients to experiment with explosives or to manufacture illicit drugs.

BCCE 2014

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!

Floating Squares

floating squares

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.
