Chemistry Now

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

"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.

How atoms bond: Ionic bonds

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.

Chance Discoveries: Polyethylene

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.

Origami Chemistry: NYU Professor Folds Molecules

21st Century Chemist Kent Kirshenbaum of New York University engineers and folds synthetic peptoids in hopes of creating "hunter-killer" molecules that can target and destroy deadly bacteria like staph (MRSA).

Chemistry Of Ice

"The Chemistry of Ice" explains what happens when liquid H2O freezes into a solid crystal.

Chance Discoveries: Cellophane

A Swiss chemist tries to stain-proof tablecloths by coating them with a viscous cellulose-based liquid, but it peels off in clear sheets when it dries. That new material, when refined, revolutionizes the way food is packaged and sold.
