One bond can make all the difference
The National Science Foundation has joined forces with NBC Learn and the National Science Teachers Association (NSTA) to celebrate the International Year of Chemistry by creating "Chemistry Now" - a weekly, online, video series that uncovers and explains the science of common, physical objects in our world and the changes they undergo every day. The series also looks at the lives and work of scientists on the frontiers of 21st century.
"Chemistry of Fear and Fright" explains how two hormones, adrenaline and cortisol, work to trigger a cascade of "fight or flight" fear responses when you're confronted by a spider, great height or snake.
This video uses common table salt to explain and illustrate what happens between the electrons and protons in atoms of the element sodium and atoms and the element chlorine to make crystals of sodium chloride.
