Balancing Chemical Equations
Students use the Molecular Model Set to model the law of conservation of matter during chemical reactions.
Chemical Reactions
Students predict products of a series of chemical reactions and use a temperature, conductivity, and pH sensor to verify a chemical change.
Solubility Rules
Students look for patterns to experimentally determine the solubility rules for a set of solutions.
Conservation of Mass
Students experimentally determine the amount of sodium bicarbonate in an antacid tablet based on the mass of carbon dioxide formed when the tablet reacts...
Percent Yield
Students analyze a precipitate product to determine the percent yield of a reaction.
Modeling Limiting Reactants
Students use the Molecular Model Set to simulate reaction scenarios where there are limiting and excess reactants, and ideal reactions where all reactants...
Determining Limiting Reactants
Students use a Pressure Sensor to experimentally determine the limiting and excess reactant when the amount of one reactant is varied and analyze data...
Project: Design an Airbag
Students must engineer an airbag that inflates and uses materials according to a set of design and performance constraints; a temperature and pressure...
Research Enhancement: Airbags and Consumers
Students research and write about the chemistry and function of airbags used as either wearable protection...
Isotopic Composition
Students work with model “element samples” to learn the characteristics of isotopes.
