"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.
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.
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.
This video tells the story of how the world's most used plastic was first formed and developed into the "miracle" material of post-WWII America.
The links between molecule structure and physical properties.
Responding to the months-long oil spill from a BP well in the Gulf of Mexico in 2010, a team of polymer chemists in Mississippi set to inventing a non-toxic chemical dispersant that could break up oily deposits without harming marine or wetlands wildlife.
