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.
Homeostasis
Students use multiple temperature probes simultaneously to investigate the body’s ability to maintain homeostasis when subjected to a cold stimulus.
Cellular Respiration
In this lab, students use a carbon dioxide gas sensor to measure the rate of cellular respiration of germinating seeds. Students will design and conduct...
Fermentation
In this lab, students determine the ability of yeast to use different types of carbohydrates—sucrose and starch—for fermentation and monitor the reaction...
Photosynthesis
In this lab, students test how light influences the rate of photosynthesis.
Plant Pigments
In this lab, students will extract pigments from spinach leaves and analyze their samples using chromatography and colorimetry.
Transpiration
In this lab, students investigate the rate of transpiration in plants under normal and humid conditions. Then, they will have the opportunity to design...
