How can I engage my students (and myself) for the last half of the semester? I read recently that the human attention span in 2015 is 8.25 seconds(link is external), which is down from 2000’s 12-second span. Currently, we are just beneath goldfish, who can attend to one thought for 9 seconds. I’m not sure of the methods of the research study, and I maintain a level of healthy skepticism.

Flinn Scientific has a great elearning video series. Many of the videos have master teachers demonstrating some great labs and techniques that they do in the classroom.
Every October I get excited; not as much for halloween, but rather for Mole Day! I have been a member of the National Mole Day Foundation (NMDF) since the beginning of my career and enjoy celebrating with my students. My first year of teaching we (the chemistry classes) hosted
Modeling InstructionTM is specifically designed so students construct meaning without being told what to think and I needed videos that aligned with this philosophy. That’s when I ran across this TedEd talk with Dr. Derek Muller.
KWIPPED is a highly efficient, no-cost resource for chemistry teachers looking to rent equipment for projects. If you need to source equipment that is too expensive to buy, KWIPPED.com is a great way to find short or long-term rentals that will fit your budget.
The HaberFilm.com website is a helpful resource for teachers that have interest in using the Haber video in their curriculum. Reading materials and lesson ideas are available. I recently used a lesson that my colleague created directly from the provided materials. You can check out that lesson here. The lesson included some background reading, viewing the video, participating in an excellent discussion and a follow up writing assignment.
