Mitosis
After learning the technique for growing roots and preparing root tip squashes for microscope analysis, students observe the root tips for evidence of...
BLAST Bioinformatics
Students analyze the DNA and protein sequences of beta globin of five mammalian species to determine their evolutionary relatedness.
Plant Pigments
Students analyze spinach pigments and chloroplasts using paper chromatography, a colorimeter, and a spectrometer to understand how plants capture light...
Transpiration
Students use a pressure sensor and a weather sensor to investigate the rate of transpiration in plants under normal and humid conditions.
Photosynthesis
Students use a carbon dioxide gas sensor to test the effect of the color of light on the rate of photosynthesis.
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.
