As school districts across the country approach the implementation of the Next Generation Science Standards, students will be required to develop models to illustrate what occurs at an atomic level as well as apply various mathematical representations in order to explain a science-based concept. However, what opportunities are we providing our students to allow them to explain what they know about a concept? Students should be provided with regular opportunities to develop and explain concepts, which in turn will allow teachers to formatively assess and address misconceptions.

I have a first day routine that I am very proud of. I have used it for 25 years and I think I finally have it down pat. I have spoken to students from 20 years ago at reunions and they tell me that they still remember the first day of chemistry so I think it is pretty good.

What a mole-riffic time we are having here in Kennesaw, Georgia!  Some highlights from my time here include:

~ The very appropriate cooling towels (Chill-its) we (ChemEd X) handed out to folks who stopped by our table, ran the Mole Run, or we saw between sessions. Several teachers have been diving in to research how they work.  Chemistry in action!

During our recent chemistry summer camp, we used some electrochemistry activities. We had some logistical issues, but they were an overal success!

Edmodo, Coursesites, Schoology…which digital learning platform is best for you? I’ve been searching for the right, free fit for me for the last three years. My journey has taken me from Edmodo to Coursesites to Schoology. I learned four valuable lessons about myself along the way that may help you make your own decision.

It was Oregonians only (lucky me!) for PBS’s limited release of The Mystery of Matter: Search for the Elements in fall 2014. A national premiere is now at hand—mark your calendar for your local station’s broadcast.

The video displays a neat trick you can do for your students. What do you suppose is the secret behind this trick? Hint: >It has to do with chemistry!

If you are like me and pretty much what seems like ALL of my high schools students, then you probably have a mobile device near you and you are also aware of the effect water has on turning that most precious piece of  “I can’t live without it” into a paperweight.

Over the past two years, I have immersed myself in designing mobile games for organic chemistry: founding a company called Alchemie and building a team to develop these games. The first of our games is called Chairs! (The exclamation point comes from the fact that an app called Chairs already existed in the AppStore.) The game Chairs! is what we call our proof-of-concept. Folks were a bit incredulous when we told them we design games that make learning organic chemistry intuitive and fun.
