Volume of Breath
Students investigate how the amount of air moving in and out of the lungs changes with exercise.
Plant Respiration and Photosynthesis
Students use a carbon dioxide sensor to measure the rates of photosynthesis and respiration in spinach leaves.
Solution Concentration: Beer's Law
Students will measure the absorbance of known solution concentrations in order to determine the unknown concentration of a solution.
pH of Household Chemicals
Students will use a pH sensor to determine the pH of common household substances.
Enzyme Activity (Oxygen)
Students will use an oxygen gas sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
Enzyme Activity (Pressure)
Students will use a pressure sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
