You can choose which module to study from the available options for this component. There may be limited opportunities to continue on the course/be eligible for the qualification if you fail.
The modules that are available for you to choose for each component will depend on several factors, including which modules you have chosen for other components, which modules you have completed in previous years of your course, and which term the module is taught in.
Modules
Modules are the individual units of study for your course. Each module has its own set of learning outcomes and assessment criteria and also carries a certain number of credits.
In most cases you will study one module per component, but in some cases you may need to study more than one module. For example, a 30-credit component may comprise of either one 30-credit module, or two 15-credit modules, depending on the options available.
Modules may be taught at different times of the year and by a different department or school to the one your course is primarily based in. You can find this information from the module code. For example, the module code HR100-4-FY means:
HR
100
4
FY
The department or school the module will be taught by.
In this example, the module would be taught by the Department of History.
This module will introduce you to the major themes of sustainability along with the most recent developments. Topics include environmental sustainability issues like water, food, and energy; social sustainability themes like environmental justice and transportation; and economic sustainability topics like green businesses and economic development as well as sustainability issues in universities. We will use case studies to explore examples and understand the issues and future of sustainability.
Why do we all look different? Are some illnesses hereditary? Are animals born ready-suited to their environment? From the early theories of Mendel to modern studies in molecular genetics, you explore how scientists have answered these questions over the last 150 years.
Examine how the structure and function of DNA allows genetic material to be expressed, replicated and inherited, and consider how genetic variation leads to adaptive evolution. From developing new technologies in gene cloning to the applications for modern medicine, you explore how geneticists are building on the earlier achievements in this fundamentally important field to enhance our understanding of life on earth.
Develop your skillset and boost your CV. This module prepares you for the coursework, laboratory practicals and research projects that you will encounter during undergraduate study. Get to know referencing systems and learn how to effectively communicate scientific information. Use scientific units and simple algebra and demonstrate understanding of logarithms, exponentials, geometry and elementary calculus. Learn how to design experiments, handle data and display, interpret and analyse basic statistics.
Teaching and learning will be through a mixture of lectures, classes, practicals and tutorials, with an emphasis on developing the key transferable skills needed for a career in biosciences.
You will develop your transferable skills in scientific writing (including referencing and avoiding plagiarism), teamwork and communication through oral presentations, study and research skills (including essay writing, lecture note taking, use of library and databases). Teaching and learning will be through a mixture of lectures, classes, and tutorials. The emphasis will be on small group, tutorial-style teaching and interaction with other students on this module, with assessments tailored to your degree subject area.
This module develops knowledge from the exploration of the major themes of sustainability. Case studies will be used to deepen knowledge and explore specific examples from each facet of global sustainability. We will critically examine the current action being taken at the local and global scale.
Professional skills for Ecological and Marine Scientists
(15 CREDITS)
In this career-focused module you develop skills specific to your discipline, such as information retrieval, data-analysis and interpretation techniques, as well as a broader range of transferable skills, such as communication, team-work, numeracy and attention to detail. Learn how to best approach job applications, including CV and cover letter writing, aptitude testing and the interview process.
This final-year research project is an opportunity to carry out an individual investigation on the topic of your choice relating to Global Sustainability.
You will use the skills and knowledge developed in the course to identify a suitable question with the guidance of an academic supervisor. Then, you will conduct a desk-based (or short field-based) approach to addressing your research questions.
The qualitative or quantitative analysis and presentation will take the form of a report to demonstrate research, understanding and critical thinking about the literature relating to your research topic.
Earth`s climate has fluctuated throughout history, but the speed of change in recent decades has been unprecedented. Warming, acidification, drought, flooding, and fire are increasingly prevalent features of our modern world.
In addition, humans are responsible for widespread environmental pollution, which is any input of material or energy into air, land, or water that causes harmful environment change.
The sources and ecological consequences of climate change and pollution will be explored and discussed, concentrating on biodiversity, species distributions and extinctions, and the provision of ecosystem services of benefit to humans.
Examples of climate change and pollution will be presented from both terrestrial and aquatic domains, and from polar to tropical biomes, together with a review of the avenues to be followed for remediation of biosphere processes and the conservation of biological diversity. The module will be delivered through lectures and a practical session incorporating data analysis and interpretation.
On a placement year you gain relevant work experience within an external business or organisation, giving you a competitive edge in the graduate job market and providing you with key contacts within the industry. The rest of your course remains identical to the three-year degree.
Year abroad
On your year abroad, you have the opportunity to experience other cultures and languages, to broaden your degree socially and academically, and to demonstrate to employers that you are mature, adaptable, and organised. The rest of your course remains identical to the three-year degree.
