Making Measurement Meaningful or Why to Avoid Saying "Sig Figs" in Class.

Gluging in Class

Every year when the day came to discuss the rules for significant figures in measurements with my classes I would write the rules on the board, we’d work through a couple examples, and I’d try to find a way to explain why we needed to use them when reporting measurements.  This has never been my favorite topic to teach, mostly because I had a difficult time helping students see why these rules for measurement and reporting uncertainty were important.

AACT: A Community for K–12 Teachers of Chemistry

AACT

On September 2, the American Association of Chemistry Teachers (AACT) launched its official website, loaded with lots of resources and member benefits. If you visit teachchemistry.org, you will find many great tools that K–12 teachers of chemistry can use in their classrooms; the new online periodical, Chemistry Solutions; professional development opportunities; and a community for you, in addition to many other benefits.

Inquiry at BCCE

Mon, 08/04/2014 - 16:26 -- Sarah Kong

Happy BCCE week to y'all!  I am enjoying being back at my alma mater, Grand Valley State University.  This morning I attended a symposium focusing on what it means to be a professional and how to continue to grow throughout your career.  The strand running through each presentation was time and collaboration.

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.)

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.
