CHM 124 L - Environmental Science II Laboratory
A continuation of CHM 123L Environmental Science Laboratory emphasizing the use of approved methodology, field trips, and a special project to study environmental problems of both local and global interest.
Corequisite: CHM 124 Environmental Science II
3 Laboratory Hours
Learning Outcomes of the Course:
Upon successful completion of this course the student will be able to:
- Produce ASTM 6751 biodiesel from waste vegetable oil collected from local restaurants.
- Measure the BTU content of various biomass fuels using bomb calorimetry.
- Construct a fully functional wind turbine.
- Measure the variation in wind turbine output based on height above ground, wind speed, distance from any obstruction, and rotor rpm.
- Calculate the instantaneous and maximum current, voltage, and power for a wind turbine.
- Calculate the minimum wind speed required to generate power and the average power that can be generated anywhere in the U.S. based on NOAA records.
- Measure the variation in current, voltage, and power in a photovoltaic array based on load, angle, direction, solar constant, and cloud coverage.
- Calculate the instantaneous and maximum current, voltage, and power for a PV array.
- Connect a wind turbine, PV array, lead storage battery, load monitor, and inverter to run various loads in the Natural Science Center.
- Construct and operate a fully functional electric car (NEV) with a photovoltaic charging system.
- Research a local environmental problem and present it to the class.
Methods of Assessing Outcomes:
The expected learning outcomes will be assessed through the use of laboratory reports, formal papers, and group presentations.
