Thing Explainer: Complicated Stuff in Simple Words by Randall Munroe

How did someone figure that out? Can you explain to me why this happens? No matter the topic, individuals are always seeking information as they look to explain complex objects and theories. “Thing Explainer: Complicated Stuff in Simple Words” by Randall Munroe uses only one thousand of the most common words to explain various inventions and phenomena in the field of physical science.

The Big Picture- My First Year Chemistry Scope and Sequence

Guiding principles in my scope and sequence: Start with a simple representations of the nanoscopic and dig deep. Hopefully, by the time we start with vital, albeit often more challenging symbolic representations (mole, stoichiometry, solutions), students have a decent foundation to build upon.

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.


Jenelle Ball - An Inspirational Awardee

Jenelle Ball

I met Jenelle Ball in Denver, CO at the Spring 2015 National ACS meeting. She is soft spoken and engaging. Jenelle’s biographical information is impressive. She earned a BS and MS in chemistry. While in graduate school, she recognized a passion for the process of teaching and learning which led her to teach high school chemistry. Most of her career has been spent at Chico Senior High School in Chico, CA. She was also fortunate to have the opportunity to take a rare sabbatical from high school teaching and earn a MA degree in teaching and learning.

PASCO Wireless Temperature Sensor, update on Classkick and with exams coming soon try High School Chemistry: Practice Tests and Flashcards by Varsity Tutors

This past week, as part of our Thermochemistry unit, my students were completing one of my favorite Target Inquiry Labs entitled “ A Very Cool Investigation”.  We were using calorimeters, dissolving ammonium nitrate, and my students were recording the change in temperature using a digital thermometer.  Some of my students had noticed that with si

Ways to recharge during the summer...consider joining the AACT or getting involved in your local ACS


As with most conferences, even the small ones, there is way more than I could put in one blog. Here is what impressed me the most. Several people from the national and local ACS made a point of doing whatever they could to reach out to teachers. As Dr. George Bodner said (and I am paraphrasing), the ACS first looked at what they could do to teachers. They then examined what they could to for teachers. Now they are asking, "How can we work WITH teachers.

AP Chemistry Survey

Shedding Light on AP Chemistry

Chemistry education faculty at Stony Brook and Carnegie Mellon University want to help AP chemistry teachers adapt to the new AP curriculum, and will create a new website to help support teacher needs: the APChemCollaborative (APCC). Could you please take a moment and help us understand you and your needs better, so we can create a successful design?

Doc Saves Everyone – Applying BCA Tables to Titration Calculations

doc saves everyone

I recently stumbled across a blog about the use of BCA (Before Change After) tables for stoichiometry written by Lowell Thomson.  I was thrilled to discover ChemEd Xchange!  I wanted to share my journey, spurred on by my students, into the extensive use of the BCA approach in AP and IB chemistry.  I hav
