Alcohols (16-19)
Propanol is a common alcohol used in hand sanitizers. The many forms and uses of alcohols fill an intriguing lesson. Scholars apply logic to match alcohols, chemical structural formulas, oxidation products, and more in a series of puzzles.
Royal Society of Chemistry
The Blast Furnace
The largest chemical reactors are blast furnaces, used to make iron from ore. Scholars explore reactants by first matching each one to its purpose and formula. Then, a series of three gridlock puzzles reinforce the content while...
