From Ellen McHenry’s website:
This curriculum is designed to be a follow-up to The Elements. The style of the text (including the bits of whimsical humor) are the same as in “The Elements,” but the student text is more substantial and requires more reading.
Topics covered: A quick review of what an atom is, three types of atomic models, an overview of the carbon atom and its allotropes (diamond, graphite, buckyballs), introduction to organic chemistry (alkanes, alkenes, alkynes, e.g. methane, propane, butane), refining of crude oil, isomers, saturated and unsatured molecules, functional groups (alcohols, carboxylic acids, aldehydes, ketones, esters, ethers), combination of functional groups (sodium benzoate, nitroglycerin, soap, pheromones), plastics and polymers, rubber and silicon polymers, carbohydrates (simple sugars, starches and cellulose), fats (saturated, unsaturated, trans and cis fats), proteins (amino acids, polypeptides, protein folding and its significance, the lock and key principle, structure of DNA), and finally the carbon oxides (like CO2) and the carbon cycle.
(For those of you are “chemistry-shy”, don’t let this list scare you– everything is presented in ways that both you and your student will understand completely.)
Activities included: A comprehension self-check list of questions for the student at the end of every chapter, on-line research questions at the end of every chapter, some pencil and paper word puzzle activities (crosswords, etc.), building models of carbon’s allotropes, organic molecules card game, burning experiments, counting carbons song, paper chain alkanes, make marbled paper, benzene ring dance, functional group card game, experiments with acetic acid, isopropanol, and acetone, experiment with soap and surface tension, benzaldehyde snack, recycling plastic relay race, sorting plastics using chemical analysis, experiments with water-absorbing polymers (found in diapers), plastic product testing, the Plastic Song, skit about Charles Goodyear, skewering a balloon, demonstrating molecular motion using a plastic polymer, making “slime,” experiments with Silly Putty, testing for starch, artificial sweetener taste tests, glycogen tag game, cake recipe testing (for fats), insulation experiment, The DNA Song, experiment with an enzyme, using rennet in a recipe, the carbon cycle board game, and suggestions all through the text of websites to visit for extra info and activities. In addition, there are instructions for how to throw a “polymer party” to wrap up your unit. There are extra review games, as well as ideas for snacks and decorating.
