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.

Prerequisite- Corequisite
Corequisite:  CHM 124 Environmental Science II

Credits: 1
3 Laboratory Hours
Course Profile
Learning Outcomes of the Course:

Upon successful completion of this course the student will be able to:

  1. Produce ASTM 6751 biodiesel from waste vegetable oil collected from local restaurants.
  2. Measure the BTU content of various biomass fuels using bomb calorimetry.
  3. Construct a fully functional wind turbine.
  4. Measure the variation in wind turbine output based on height above ground, wind speed, distance from any obstruction, and rotor rpm.
  5. Calculate the instantaneous and maximum current, voltage, and power for a wind turbine.
  6. 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.
  7. Measure the variation in current, voltage, and power in a photovoltaic array based on load, angle, direction, solar constant, and cloud coverage.
  8. Calculate the instantaneous and maximum current, voltage, and power for a PV array.
  9. Connect a wind turbine, PV array, lead storage battery, load monitor, and inverter to run various loads in the Natural Science Center.
  10. Construct and operate a fully functional electric car (NEV) with a photovoltaic charging system.
  11. 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.
