Environmental science and climate change sample courses

  • ESCI 301 Soil Analysis

    This course involves detailed study of the biological, chemical, and geological components of soil, soil types, and soil health. Topics covered include principles and processes in soil chemistry, soil taxonomy, soil geography, and erosion. Additionally, students will explore the role of organic materials in soil health and type, general roles of soil properties on vegetative nutrient uptake, and the role of soil on nutrient and chemical cycles.  Throughout the course of the term, students will pursue a project related to soil’s influence on environmental health and sustainability.

  • ESCI 305 Environmental Remediation and Toxicology

    This course is focused on the basic concepts of and science behind environmental toxicology, including processes related to remediation and contaminant mediation. Topics include the underlying biological processes such as bacterial metabolism, enzymatic activity, anaerobic and aerobic biodegradation, and an overview of remediation of inorganic contaminants. Students will additionally explore the fate and effects of chemicals in organisms in the environment, including air, water, and ground pollutants.

  • ESCI 401 Environmental Science Field Techniques Laboratory

    Learn and apply various field and laboratory techniques used in environmental science. Gain skills used in both professional field (e.g. wetland delineation, aquatic macroinvertebrate sampling) and lab (e.g. sediment analysis, water chemistry techniques, software applications for analysis) settings.
