Title of Module: Trace Evidence & Microscopy

Code: CHEM09008 SCQF Level: 9
(Scottish Credit and Qualifications Framework)
Credit Points: 20 ECTS: 10
(European Credit Transfer Scheme)
School:School of Computing, Engineering and Physical Sciences
Module Co-ordinator:Ciaran  Ewins

Summary of Module

Trace evidence has become crucial to forensic science, as techniques such as microscopy and spectroscopy have advanced. This module examines the sources and the physical nature of the various types of trace evidence especially hairs, fibres, geological materials and also biological trace evidence such as insects, pollen grains and phytoplankton. Microscopical techniques to gain quantitative and qualitative information from these evidence types are then introduced.

The management of scenes of crime for trace evidence preservation, collection and packaging are introduced. Laboratory work is important in this area and time will be spent in the lab using light and polarising light microscopes to examine trace evidence , recovering trace material from evidence, carrying out infra red spectroscopy and microscopy of fibres and electron microscopy with x-ray analysis of trace materials.

This module will work to develop a number of the key 'I am UWS' Graduate Attributes. Those who complete this module will have developed academic competencies in report writing and problem solving and practical knowledge and skills related to research and laboratory work in Forensic Science.


Module Delivery Method
Face-To-FaceBlendedFully Online
check mark

Face-To-Face
Term used to describe the traditional classroom environment where the students and the lecturer meet synchronously in the same room for the whole provision.

Fully Online
Instruction that is solely delivered by web-based or internet-based technologies. This term is used to describe the previously used terms distance learning and e learning.

Blended
A mode of delivery of a module or a programme that involves online and face-to-face delivery of learning, teaching and assessment activities, student support and feedback. A programme may be considered “blended” if it includes a combination of face-to-face, online and blended modules. If an online programme has any compulsory face-to-face and campus elements it must be described as blended with clearly articulated delivery information to manage student expectations
