Optimum Conditions
Students use a pressure and temperature sensor to observe the effect of changing various experimental conditions on the rate of a chemical reaction.
Equilibrium Reactions
Students model an equilibrium reaction at the particle level as well as the visible level.
Titration of an Unknown Acid
Students use a pH sensor to conduct a strong acid and weak acid titration with a strong base.
Antacids: An Inquiry Study
Students use a pH sensor to investigate how antacid tablets work and use a back titration method to determine how much of the active ingredient is found...
Lemon Battery
Students use a voltage sensor to measure voltage produced by a lemon battery with copper and zinc electrodes, then use their data to design a lemon battery...
Half-Lives
Students model radioactive decay to determine the half-life of a “radioactive” sample.
Chlorophyll Extraction
Students use a colorimeter to investigate which wavelengths of light are best absorbed by green plants.
Respiration and Energy
Students use a Pressure Sensor to explore the effect of different energy sources on the respiration rate of yeast cells.
Greenhouse Gases
Students use a temperature sensor to investigate how changing the composition of air affects the rate at which its temperature will increase when energy...
Ocean Currents
Students use a Temperature Sensor and a Conductivity Sensor to investigate the driving forces behind ocean currents.
