  • How to Name Ionic and Covalent Compounds
    Mr. Causey teaches you how to use the periodic table, a list of polyatomic ions and prefixes to name ionic compounds and covalent compounds. Master chemical nomenclature by learning a few rules and an easy to follow system.

  • Carbon: Why is it essential for life as we know it?
    Carbon is the basis of all organic molecules. It is also one of the most abundant elements in the universe. This video segment adapted from NOVA illustrates the special characteristics of carbon that make it an essential ingredient for life.

  • NBC Now: Cheeseburger Chemistry Videos
    This original six-part Chemistry Now video series uses components of a cheeseburger to illustrate and explain common chemistry concepts and reactions. The Bun? Gas and sugar reactions. Cooking burgers? Heat, protein and Maillard reactions. Cheese? Phase change, from liquid to solid, and coagulation. Tomatoes? The role of ethylene in ripening and lycopene in color change, and gas diffusion. Pickles? Fermentation, acid and pH. And condiments? Mixtures: suspensions (ketchup and mustard) and emulsions (mayo and mayo-based special sauces).

  • NBC Now: It's a Wash -- the Chemistry of Soap
    “It's a Wash: The Chemistry of Soap” explains how soap and detergents — surfactants — affect the surface tension of H2O to break up greasy dirt. We also profile 21st Century Chemist Facundo Fernandez at Georgia Tech, who uses chemistry to detect dangerous or ineffective fake pharmaceutical drugs and medicines. Also in this collection: news stories from the archives of NBC News and Scientific American on counterfeit drugs, and on hand-washing and the spread of germs and disease; plus, a history of soap timeline and Victorian-era soap recipes.

  • A dialogue with Sarah, Aged 3: In which it is shown that if your Dad is a chemistry teacher, asking "why" can be dangerous!

  • NBC Now: Why does it act like that?
    In this original Chemistry Now video and animation series, a dozen molecules and compounds are “profiled” to explain what makes H2O watery and soap soapy; why salt dissolves in water and how soap dissolves grease; why spearmint, dill, cloves and nutmeg have different tastes and aromas; and why grass is green, roses are red and violets are, well, violet. Also covered: molecular bonds (single, double, covalent, hydrogen, ionic); the Octet Rule, deprotonation, acids and bases, surfactants and surface tension, crystal lattice structures, polymers, polyamides and allotropes.

  • NBC Now: Carbon Captured -- Carbon Dioxide (Carbon Cycle, Octet Rule, CO2)
    “The Chemistry of CO2: Carbon Dioxide,” uses CO2's molecular structure to explain and illustrate the Octet Rule (Rule of 8); and examines CO2's role in carbonation, the carbon cycle, and the Earth's atmosphere, surface temperature, and ocean acidity. Also in this collection: stories from the NBC Learn-NSF “Changing Planet” series; stories on CO2 emissions, capture and storage from the archives of NBC News and Scientific American; and charts and graphs on CO2 output trends.

  • NBC Now: Bullet-proof Chemistry -- Kevlar
    As light as nylon yet harder than steel — “Chance Discoveries: Kevlar” tells the story of lab experiments with aromatic polyamides that produced the synthetic material now common in bicycle helmets, tires, and “bulletproof” police and combat gear (although not in fashion, despite the early designs of one apparel company). Also in this collection: stories from the archives of NBC News, Scientific American, and The Washington Post on early and current uses of Kevlar, and advances in anti-ballistic materials.

  • NBC Now: The Chemistry of Fear and Fright (adrenaline and cortisol)
    Are you arachnophobic? Acrophobic? Ophidiophobic (afraid of snakes)? “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. Also in this collection: news stories from the archives of NBC News and Scientific American on common fears and phobias; a Word Root on the origin of “phobia”; and a photo slide show of common fear response triggers.

  • NBC Now: The Chemistry of Smell
    Smell that? Our sense of smell is a complex set of chemical reactions. We profile 21st Century Chemist Nate Lewis, who's working to develop an artificial “nose” that can help detect odors, including hazardous gases and chemicals. A story on the carvone molecule adds information on how the nose distinguishes odors. Also in this collection: news stories from the archives of NBC News and Scientific American on air testing, sense of smell (human and canine) — and a Periodic Table of “Smellements.”

  • NBC Now: The Chemistry of Biotoxins -- Pain Relief
    It's both horrifying and fascinating, the way venomous sea snails paralyze, then kill, their prey. We profile 21st Century Chemist Mande Holford of the City University of New York, who is working to synthesize these biotoxins and develop powerful new painkillers. Also in this collection: news stories from the archives of NBC News and Scientific American on snail, spider and cobra venom, and on pain sensation and control — and a “universal” pain-rating scale.

  • The Chemistry of Sports

  • Chemistry in your Cupboard
    The material in this site consists of nine pieces each describing the chemistry that underlies a household product from the range produced by Reckitt Benckiser (although other branded products will work in similar ways). The products range from pharmaceuticals (Nurofen, Gaviscon) to cleaning materials (Cillit Bang, Finish).

  • Mass Spectrometry 101:
    This video from NASA describes and animates the process by which mass spectrometry can identify chemical composition of matter. One example - a specific inquiry about Mars - is described, with reference to many other applications.

  • The Shape of Molecules: An interactive tutorial
    This interactive activity from ChemThink explains the valence shell electron pair repulsion (VSEPR) theory. Understand why, within a covalently-bonded molecule, areas with a higher concentration of electrons repel each other to be as far apart as possible. See how Lewis structures can be used to predict the shape of a molecule, and learn about common molecular geometries such as linear, trigonal planar, bent, tetrahedral, and trigonal pyramid.

  • The Shape of Molecules: Tyler DeWitt Video
    This is an introduction to the basics of VSEPR Theory. VSEPR theory is a set of rules for how to look at a Lewis structure and determine the three dimensional (3D) shape of a molecule. The shapes have to do with the location of bonds and lone electrons pairs. In this video, we'll look at the following shapes: linear, trigonal planar, bent, tetrahedral, and trigonal bipyramidal
