CHEM00020 Introductory Chemistry

Academic Year 2021/2022

This module introduces to first-year agricultural and veterinary nursing students the basic principles of chemistry and how this central scientific discipline applies to different fields of agriculture, including food science, farming, aquaculture, forestry and veterinary science. Topics include the structure of the atom and molecules, understanding and measuring physical properties including mass, volume and density. A discussion of the first experiments that helped identify parts of the atom and how these components combine to build molecules. The concept of ionic and covalent bonding is demonstrated, in addition to the principles of chemical reactions. Students learn how to correctly balance chemical equations, applying the concept of limiting reagents, and calculate molecular mass, molarity and concentrations. There is an introduction to the different phases of matter and the idea of inter-molecular forces and how the type and strength of these forces are related to gases, liquids and solids. Students learn about the concept of gases, including the ideal gas law. A detailed section is provided on the roles of acids and bases in food science. The course finishes with an examination of energy and thermodynamics. Due to the strong association of agriculture and nature, several key environmental concepts are covered, including reactions in the atmosphere and how the water cycle operates. The content of the course is delivered through on campus lectures. There are 4 experiments to be completed with topics based on concepts discussed in the lectures. Continuous assessment consists of 8 online quiz completed on Brightspace, and 4 in-class quizzes written in the in-class tutorials.

Learning Outcomes:

Students will learn how to write and balance chemical equations containing molecules and or ions. They learn about inter-molecular forces and understand the ideal gas law. They will be the calculate the pH of solutions and foods, and predict what compounds are readily oxidised or reduced. Students will be able to solve basic energy and thermodynamic problems and become aware of agriculturally related environmental issues associated with the atmosphere, lithosphere and hydrosphere. A combination of in class and online tutorials will assist in the developing techniques for problem-solving and establish theoretical concepts to real-world problems. Moreover, four practical laboratory sessions demonstrate how standard chemistry methods can be applied to identify the composition of common agricultural materials, including fertiliser.

Approaches to Teaching and Learning:
Lectures are given face to face on campus but will also be available through lecture capture and thus can be accessed any time post live lecture. Students are required to complete all 8 online tutorials through Brightspace with a deadline of one week. A series of example problems related to online quizzes are available on Brightspace. Learning is supplemented by 4 face-to-face tutorials where the tutor covers a selection of sample questions related to the final exam. Each student needs to write a short quiz at the end of each tutorial. There are 4 practical experiments to be completed in the School of Chemistry undergraduate laboratories and allows students to perform chemical analysis on agricultural-related materials. A final 2-hour exam (a combination of MCQ and fill-in-the-blank calculation problems) is based on all material given through the trimester. The exam may be written in person or held online, and the decision is to be communicated during the trimester.
