Organisms and pH
Students use a pH sensor to determine how effective various substances are at resisting large changes in pH.
Membrane Permeability (pH sensor)
Students use a pH sensor to explore which substances can and cannot pass through a cell membrane model.
Enzyme Action - Oxygen Sensor
Students use an oxygen sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
Enzyme Action - Pressure Sensor
Students use a pressure sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
Animal Behavior
Students use a choice chamber to test the response of fruit flies to different stimuli and determine if there is a significant change in their behavior.
Population Genetics
Students determine their phenotype for the PTC (phenylthiocarbamide) tasting trait and use class data to derive allele frequencies for a population.
Artificial Selection
Students follow the growth and development of Wisconsin Fast Plants and determine if limiting cross-pollination to certain plants with a desired trait...
Enzyme Activity (Spectrometer)
Students use a spectrometer to investigate the catalyzed breakdown of hydrogen peroxide by peroxidase.
Energy Dynamics
Students use EcoChamber containers and a carbon dioxide gas sensor to estimate energy flow and carbon cycling within a variety of detritus-based ecosystems.
Meiosis
Students use physical models of chromosomes to explore meiosis and genetic variation, and use cross over rates observed in Sordaria to calculate gene distance...
