Curated OER
Antacid Tablet Race
Students compare the reaction rates of effervescent antacid tablets under different conditions. They investigate methods of increasing the power of rocket fuels by manipulating surface area and temperature.
Curated OER
Acids, Copper, and Zinc
Students observe chemical reactions using post-1982 pennies. They observe the reaction of an acid with zinc but not copper under the same conditions over a two week period.
Curated OER
Chemical Weathering
Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.
