Four Ways to Fight Spring Fever

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. However, I admit my thoughts often spring from topic to topic like a bubble gum machine bouncy ball.

Veritasium in the Modeling Classroom

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

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. 

Haber - The Father of Chemical Warfare

The  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.  The lesson included some background reading, viewing the video, participating in an excellent discussion and a follow up writing assignment.

 

Making Measurement Meaningful or Why to Avoid Saying "Sig Figs" in Class.

Every year when the day came to discuss the rules for significant figures in measurements with my classes I would write the rules on the board, we’d work through a couple examples, and I’d try to find a way to explain why we needed to use them when reporting measurements.  This has never been my favorite topic to teach, mostly because I had a difficult time helping students see why these rules for measurement and reporting uncertainty were important.
