Vernier BGP-DIN Biology Gas Pressure Sensor. Interfaces and software (not included) are always sold separately.
Many biology activities involve the production or consumption of a gas, resulting in a change in pressure. The Biology Gas Pressure Sensor can be used to monitor these pressure changes. It can be connected to any of the Vernier interfaces (ULI, Serial Box Interface, MPLI, or Voltage Input Unit), as well as the Texas Instruments Calculator-Based Laboratory™ (CBL™) System. The following is a partial list of activities and experiments that can be performed using this probe:
Monitor the production of O2 during photosynthesis of an aquatic plant in a closed system.
Determine the rate of transpiration for a plant under different conditions.
Determine the rate of respiration in germinating pea or bean seeds.
Monitor the pressure of a confined air pocket as water moves in and out of a semi-permeable membrane by osmosis.
Study the effect of temperature and concentration on the rate of decomposition of H2O2
Determine the effect of temperature on cold-blooded organisms by monitoring their respiration.
Monitor the pressure exerted as yeast ferment sugars and produce carbon dioxide.
Study human respiratory patterns using the Respiration Monitor Belt.
Investigate the relationship between pressure and volume, Boyle’s law.
Study the effect of temperature on gas pressure, Gay-Lussac’s law.
Monitor barometric pressure associated with weather phenomena.
Measure vapor pressure of liquids
