Diffusion
Students use a pH sensor to investigate the diffusion of hydrogen ions through a semipermeable membrane, comparing the rates of diffusion for two solutions...
Enzyme Activity (Oxygen)
Students use an oxygen gas sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Mathematical Modeling of Evolution
Students work with a mathematical model and computer simulation to explore how inheritance patterns and gene frequencies change in a population.
Enzyme Activity (Pressure)
Students use a pressure sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Fermentation
Students use an ethanol sensor to determine the ability of yeast to use different types of carbohydrates—sucrose and starch—for fermentation.
Enzyme Activity
Students use an oxygen gas sensor or pressure sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Diffusion
Students use a pH sensor to investigate the diffusion of hydrogen ions through a semipermeable membrane, comparing the rates of diffusion for two solutions...
Osmosis
Students use a colorimeter to determine which extracellular fluid is hypertonic to a model cell and which solution is hypotonic.
Plasmolysis
Students use a conductivity sensor to explain the results of different concentrations of salt water on plant tissue before they design an experiment to...
Cell Size
Students use temperature probes to measure the effect of cell size on cell cooling rate using cubes of potato tissue.
