Discovering Density
Students explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.
Curated OER
Molar Ratio
Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...
