Density "POGIL-Like" Activity

Mon, 07/14/2014 - 17:43 -- Shelly Belleau

Although many students have been exposed to the concept of density before reaching my Chemistry class, I always start the year with this POGIL-like activity.

Time required: 

Approximately one hour including the debrief (I recommend holding a whole-class discussion for the summarizing questions that follow the What is density? activity and a selection of mathematical computation problems from the How can you calculate density? activity.)

"The Unpersuadables" by Will Storr

The Unpersuadables, by Will Storr

Journalist Will Storr provides sixteen vignettes about people who hold decidedly minority views about scientific and historical topics. Rather than just saying, "This is what these people believe, and here is why they are wrong", Storr allows each of them to tell their own story, and lets their words speak largely for themselves.

Rainbows in a Glass Density Demonstration

Sun, 06/22/2014 - 11:34 -- Tom Kuntzleman

One day during class I presented the disappearing rainbow demonstration and explained the chemistry behind it. After doing so, I had a student ask me if a particular bartending trick called “rainbow shots” was done in a manner similar to the way the disappearing rainbow demonstration is performed.

Toward the end of the school year we inevitably have disruptions to our normal instructional day. On one day in May, our classes were shortened to only fifteen minutes to accommodate for a series of school wide exams. On this day, I decided to choose some of my favorite chemistry-themed YouTube videos and share them with my students.

To Inquiry or not to Inquiry . . .

Wed, 06/04/2014 - 18:20 -- Sarah Kong

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

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!
