Walking in the Footsteps of Scientists Who Came Before Us


I started teaching in a chronological order when I began using Modeling Instruction in my classroom. During the second year of "walking in the footprints of the scientists that came before us", I wanted my students to see where they were walking and a colleague and I came up with the idea of making footprints for each of those scientists and posting them on a timeline.

Using IUPAC's Isotopes Matter as a Digital Learning Tool

Isotopes Matter

Isotopes Matter is a digital learning tool, developed by IUPAC Isotopic Periodic Table, designed to explain isotopes as well as their importance. This resource incorporates mass spectroscopy data into each of the key ideas as well as provides multiple examples as to how varying isotopes are commonly used.

Time required: 

Using Isotopes Matter and the class discussion: 55-60 minutes

“The Candle Experiment” – an Opening Exercise for General (or introductory) chemistry

candle flame

This exercise is intended as an ice-breaker for a first or second class meeting. It also serves as an introduction to physical & chemical properties and application of the macro/micro/symbolic representations of chemical phenomena. Finally, it also provides a framework to mention many of the topics to be covered in a general chem first semester course.

My First BCCE - Vibrant High School Programming

First time at BCCE

This summer I had the opportunity to attend my first Biennial Conference on Chemical Education (BCCE) in Greeley, Colorado. When I first expressed interest in this conference more than one fellow high school educator told me some version of, “Don’t bother with that. It’s a bunch of stuff for college professors, it won’t be of use to you.” Nothing could have been further from the truth. Yes, much of the programming is directed at a higher-education audience, but many of the workshops and symposia have something to offer for precollege educators and there is a very vibrant and continually growing strand of high-school specific programing.

How do you teach resonance?

During our review since last week, resonance was labeled as one of the most tricky concepts (along with electron pushing in my opinion), despite lots of practice and instruction. My teaching sequence consists of defining and providing examples of conjugation (after learning about hybridization), delocalized electrons, and finally pushing electrons if conjugation exists. I remember from teaching at the college level that resonance was also a tricky topic for many undergraduates.

Is Your Department NGSS Ready? A Review of “What Professional Development Strategies Are Needed for Successful Implementation of the Next Generation Science Standards?” by Brian J. Reiser

Adapted from A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas, by the National Research Council, 2012, Figure 3-1, Washington, DC: National Academies Press.

With the end of the school year approaching, educators are not only developing their semester exams, they are preparing for the upcoming school year as well. Although each individual educator has their own approach to improving their curriculum, many will be spending their time off aligning their curriculum to the Next Generation Science Standards. Currently eighteen states have adopted the Next Generation Science Standards, with additional states developing their own modified version. The idea of revising curriculum for each and every course can be daunting as educators try to identify a common theme that can be applied throughout the entire department. So where do we start? How do we thread a common theme for the professional development provided in our subject area?
