You might not be aware, but this is apparently the International Year of Chemistry.
To help celebrate, NBC Learn, the educational arm of NBC News, and the National Science Foundation have teamed up to launch a weekly online video series targeting teachers and students. The videos aim to uncover and explain the science of common physical objects and the changes they undergo each day, according to a press release on the initiative.
Topics in the "Chemistry Now" series will include the chemistry behind cheeseburgers and chocolate, soap and plastics. The series will also highlight the lives and work of scientists "on the frontiers of 21st century chemistry," the announcement says.
