Product Details

Make the holiday season joyous with seven chemistry demonstrations guaranteed to amuse and enlighten the entire class. Mix two clear liquids and produce a “snowfall” of white flaky precipitate. Make two solutions of holiday green and red and watch as they suddenly switch colors. Miniature paper trees are placed in crystal growing solutions to create a forest of snow-covered firs. A triangle of copper, a drop of silver chloride, and presto, the world's smallest Christmas tree grows before the class's very eyes. Warm the holiday season with a cozy Yuletide fire of red and green. Discuss saturation and solubility while welcoming Santa Claus's arrival in a snowstorm. And finally, use “disappearing ink” to write an invisible holiday greeting that, when sprayed with a dilute basic solution, reveals the message in red and green. Concepts: Solubility, precipitation, solvation, gels, crystal formation, atomic emission, oxidation-reduction, clock reaction, buffers, acids and bases, indicators. Time Required: One full class period. Chemicals Provided: Potassium sulfate, isopropyl alcohol, sodium chloride, bluing solution, ammonia solution, calcium acetate, ethyl alcohol, lithium chloride, boric acid, benzoic acid, silver nitrate solution, formaldehyde solution, sodium sulfite, sodium bisulfite, indicator solutions, and sodium hydroxide solution. Note: Some laboratory equipment is required but not provided. Enough materials are included to perform each demonstration seven times.
