Full Title:Biological and Chemical Sciences
Module Code:AGRI S6003
Credits: 15
Valid From:Semester 1 - 2013/14 ( September 2013 )
Module Delivered in 2 programme(s)
Module Description:This module aims to familiarise students with the basic concepts, theory and practical techniques of biological, chemical and environmental sciences, which are of particular relevance to an agricultural science oriented programme.
Learning Outcomes:
On successful completion of this module the learner should be able to
  1. Recognise the fundamental principles of chemistry.
  2. Perform microbiological tests on a range of foods and farm produce for food poisoning and spoilage microbes.
  3. Appreciate the fundamental principals of biological systems from the molecular and cellular aspects of an organism to the ecosystem.
  4. Describe and relate aspects of soil biological, physical and chemical processes to soil structure and fertility, with particular emphasis alternative waste management operations in the agri-food sector.
  5. Identify and appreciate environmental issues pertaining to agriculture.
