Cellular Respiration
Students use a carbon dioxide gas sensor to investigate the rate of cellular respiration of germinating seeds.
Homeostasis
Students use multiple temperature probes simultaneously to investigate the body’s ability to maintain homeostasis when subjected to a cold stimulus....
Cell Size
Students use a conductivity sensor to measure the effect of cell size on solute diffusion rate using agarose-salt cubes.
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...
Osmosis
Students use a colorimeter to determine which extracellular fluid is hypertonic to a model cell and which solution is hypotonic.
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.
Enzyme Activity (Pressure)
Students use a pressure sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Ohm's Law
Students measure the current and voltage across a resistor while varying the output voltage, A graph of voltage versus current will reveal Ohm's Law. This...
Fermentation
Students use an ethanol sensor to determine the ability of yeast to use different types of carbohydrates—sucrose and starch—for fermentation.
