Practical science: biology and health
The activities in this module explore a range of topics in biology and health sciences, from fundamental human and animal behaviour to the vital themes of genetic variation and water quality. Online – from the comfort of your own home – you'll conduct investigations in various laboratories, in combinations of observation and experiment. You'll develop a portfolio of practical and investigative skills as you study that will contribute to your end-of-module assessment. At the end of the module you'll work collaboratively with fellow students on a team project.
What you will study
Skilled scientists reveal underlying relationships by devising questions that can be addressed safely; they report effectively and critically evaluate their findings. By studying this module you will develop and be able to demonstrate these skills.
You will carry out practical activities that you can do online, in and around your own home and that fall under the following four areas:
- Attention and the brain
- Animal physiology: cold adaptation
- Drug metabolism and genetic variation
- Water quality monitoring
Attention and the brain explores practical approaches to the study of attention. It will introduce you to practical experiments that examine how the brain functions, as well as to the careful considerations required when conducting experiments of this nature. You will conduct a study with human participants and an online, virtual experiment based on published laboratory data on animal attention. You will examine the ethical implications for both of these forms of experimental behavioural research.
In Animal physiology: cold adaptation you will investigate mammalian physiological processes using a model of acclimatisation to a cold environment. You will gain insight into the physiological and biochemical bases for adipose tissue function in thermogenesis; the process by which heat is released in the body. Using a digital microscope, you will study the anatomy and histology of adipose tissues to determine how they change with adaptation to a cold environment. You will also carry out several investigations of the biochemical changes in this tissue.
Drug metabolism and genetic variation examines how a person’s genetic make-up determines how quickly the antidepressant nortriptyline is metabolised in the body. You’ll complete a series of online experiments to estimate the purity and concentration of human DNA samples and then carry out genetic assays to determine the frequencies of gene variants within various human populations and relate these to metaboliser status.
In Water quality monitoring you will complete a series of online investigations and interactive screen experiments to assess some different aspects of water quality that are important to human health, including assessing the microbiological safety of drinking water. You'll carry one of these out as a team activity.
Method of study
During the module you will be required to use your own personal computer to access experiments and data, and to analyse and report results for the online activities. You should be prepared to set aside several periods of up to half a day for completing some of the tasks. Therefore, to study this module successfully, you must be able to study regularly (for 8-10 hours per week) and have broadband access to the internet (for up to 4 hours per week) throughout the duration of the module.
Some tasks within the module will require scheduled interactions with your tutor group. Therefore this module may not be suitable for you if you are often unavailable for study for more than a week at a time. The end-of-module assessment (team project) will require working online in a group during a period from the end of April until the end of the module, and if you are unavailable for study, or do not have regular access to a broadband internet connection, for more than a week during this time you may not be able to complete the module satisfactorily.
At the end of the module you will work collaboratively with the other students on this module using a variety of communication methods, including scheduled online forums, to carry out a team project that will require you to draw on what you will have learned in the study of one or more of the practical activities. Experience of this kind of professional teamwork is highly regarded by many employers.
You will learn
The practical and employability skills developed in this module include:
- planning and conducting observations and experiments
- data handling
- data presentation
- report writing
- awareness of research ethics
- professional team-working.
You will catalogue evidence of your achievement of these in a Skills Portfolio that forms part of the assessment.
To complete this module successfully you do need some basic mathematical skills and experience of practical observations and measurements in a scientific context. You will acquire these from the OU level 1 and OU level 2 modules in the BSc (Hons) Health Sciences (Q71) or Diploma of Higher Education in Health Sciences (W44). Or from the OU level 1 and OU level 2 modules in the BSc (Hons) Natural Sciences or Diploma in Higher Education in Natural Sciences (W37); however, you should have included at least 60 credits of OU level 2 study in the biological/health sciences – we recommend that you study SXHL288 as your final stage 2 module.
Outside of these qualifications, you will obtain an appropriate level of scientific knowledge by studying: Questions in science (S111) and Science: concepts and practice (S112); or the discontinued modules Exploring science (S104) and Investigative and mathematical skills in science (S141); or Science and health: an evidence based approach (SDK100) and the discontinued module Topics in science (S142). You should also have completed at least 60 credits of OU level 2 study from the following: Cell biology (S294), Chemistry: essential concepts (S215), Human biology (SK299), The biology of survival (S295), or the discontinued modules Analytical science (S240) and Human Biology (SK277), before starting this module.
If you have any doubt about the suitability of the module, please speak to an adviser.
Study and assessment materials will be delivered online.
You will need
Broadband internet access is required for the practical activities and a digital camera is also highly desirable to record images of your work.
A computing device with a browser and broadband internet access is required for this module. Any modern browser will be suitable for most computer activities. Functionality may be limited on mobile devices.
Any additional software will be provided, or is generally freely available. However, some activities may have more specific requirements. For this reason, you will need to be able to install and run additional software on a desktop or laptop computer with Windows 7 or higher.
The screen of the device must have a resolution of at least 1024 pixels horizontally and 768 pixels vertically.
To join in the spoken conversation in our online rooms we recommend a headset (headphones or earphones with an integrated microphone).
