Students tackle the deceptively simple task of determining the pressure of carbon dioxide gas inside a sealed soft drink can. By Hans de Grys, Journal of Chemical Education 2007, 84, 7, 1117 Abstract Soft drinks […]
Students investigate 8 household white powders and classify them based on their physical and chemical properties. Using their findings, students then identify an unknown powder obtained from a crime scene to determine […]
Students use household materials and a conductivity probe to explore factors that affect the conductivity of electrolytic solutions. Students gain experience in molarity and dilution calculations, solution preparation, nomenclature, statistical analysis, and […]
Students synthesize the copper pigment malachite, then use the pigment to prepare egg tempera paint. Students explore “stoichiometry (excess reactants and yields), solubility, precipitation, and properties of emulsions” in this Journal of […]
Use the (really fun!) reaction between the sodium bicarbonate in Alka-Seltzer tablets and vinegar to explore stoichiometry, percent composition, and limiting reactants. This experiment is easily and safely reproduced at home using […]
