I recently did a short activity with these cards and I am so glad I have them now. Being able to quickly take them out and have students look at the features of strong scientific arguments when they felt stuck writing their evidence or reasoning was powerful.
Relevant Topics for Instruction and Assessment
The August 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: the chemistry of candy and sugar, examining virtual learning for laboratories, strengthening student understanding of acid-base chemistry, building scientific communication skills, emphasizing learning, sustainability and green chemistry, cost-effective resources and techniques, laboratory investigations, ConfChem conference on mathematics in undergraduate chemistry instruction, erupting from the archive: soda geysers.
A favorite demonstration is to boil water by lowering the pressure in a bell jar using a vacuum pump. Unfortunately, purchasing a bell jar, vacuum plate, and vacuum pump can run upwards of $1,000 which poses a hardship for many teachers. Here are two simple and inexpensive demonstrations of phase equilibrium and vapor pressure.
Setup: 5 minutes
Execution: 5 minutes to 30 minutes depending on level of inquiry
Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.
In the summer of 2016, there was a Modeling WorkshopTM for High School Chemistry just before BCCE in Colorado. I already had planned to go to BCCE, so I took the plunge. Two weeks of daily instruction and labs in student mode as well as teacher mode debriefing was exhausting and exhilarating at the same time. I left with a folder and flashdrive of curriculum resources provided by AMTA (the American Modeling Teachers Association.
As a secondary science teacher, I have contact with my students everyday. Making relationships and learning about all of my students is key to letting them know that I am invested in their success.
Have you been watching the Winter Olympics? I have been able to draw many similarities and relevance to what I am teaching in the classroom. How about you?
In an effort to align my lessons with the Next Generation Science Standards (NGSS), I have tried to take the content I have traditionally taught, and shift the design to focus on student engagement with the science and engineering practices outlined in the standards. For the topic of heat transfer I re-packaged the ice melting blocks discrepant event as a NGSS investigative phenomena.

As I drive home from work every day in Houston, TX I am greeted by the entrancing voice of Dr. John Lienhard, now an Emeritus Professor of Mechanical Engineering and History at the University of Houston.
The concept of the mole has always been a challenging topic for myself and my students. The challenge comes in part when we try to imagine 6.02 x 1023 of anything. Another challenge for some students is the math and theory behind this number and concept. I have tweaked an activity to help guide my students to an understanding of these concepts.
