Biology

 

What is Biology A level about?

Biology is the easiest of the three sciences. Not because there is less to learn but because it is relevant to every aspect of your life. You don’t have to be a brilliant mathematician nor do you have to deal in symbols all the time. You don’t even have to learn lots of Latin names any more. You do, however, have to consider that Planet Earth just happens to be the right sized lump of semi-molten rock the right distance from the right sort of star, the Sun that its temperature is such that most of the water is liquid, and that it is large enough to hold a gas envelope, the atmosphere. All these factors are prerequisites for 'life'. Biologists study the life that exists on Earth from minute viruses to gigantic Blue Whales. Strange as it may seem, all organisms can be investigated under the same headings, namely: How do they reproduce? How do they get from one place to another? How do they obtain their energy? And, finally, how do they avoid becoming an energy source for other organisms?

An understanding of the principles of Biology allows students to not only appreciate how our bodies work and how diseases stop them working, but also the fragility of life on Earth. In addition a Biologist understands the potential benefits and dangers of Genetic Engineering. Once you grasp the full significance of Biology be prepared to look at the world in a new light because some day a Biologist may change it beyond recognition. Even the world of business is turning to Biology. Apparently, the behaviour of Ant colonies gives a detailed insight into the activities of large global companies. High finance uses Evolutionary models to predict the movement of share prices. Biologically related activities represent the largest concentration of wealth in the world. The whole drug industry is dependent on Biology. Biologists can tell you whether or not bio fuels reduce CO2  emissions.

 

Who does it suit?

To study Biology you must be prepared to ask the difficult questions. You have to reject the bland unscientific statements and sound bites that the media throw at you and be prepared to appreciate all around you from a biological standpoint. If you are inquisitive about the world, you will love Biology.

The AS

The new specification deals with the basic principles in relation to their effect on well known systems. For instance, instead of just looking at the structure and function of carbohydrates we now look at how they are digested and absorbed in our gut. This, in relation to fat digestion obviously has many applications to the importance of ‘diet’. Instead of just looking at the structure of bacteria we now study their role in diseases such as cholera. We start with unit 1, where, in addition to the above, we will also study the heart, lungs and general circulation and their attendant diseases.  After the January exams work will start on Unit 2 (The variety of living organisms). In order to do this we will teach you the fascinating detail of DNA. It is the developments in our understanding of DNA that has transformed Biology over the last few decades. Once you have understood how DNA codes for protein (you are made of protein) we can study the detail of transport systems in various organisms and diversity of living organisms in the natural world. During this period we will also complete the coursework (Unit 3).

 

 

The A2

 

Many consider A2 much harder than the AS and whilst it does contain some difficult topics it is even more rewarding. Basically it continues some of the themes of the AS course. Unit 4, which deals with Genetics, Evolution, Energy-release and Ecosystems, has some challenging exercises but once you appreciate the significance of what you are learning you will embrace the subject and make rapid progress. Unit 5 covers the traditional Biological topics of Physiology and Response to the environment. You will really get to grips with how nerves work, how you perceive changes in the environment and how we control reproduction. As well as revelling in the ultra-structure of muscles you will get the opportunity to relate the interaction of physiological systems with the interesting world of gene therapy. We can even make you interested in plant growth. As your knowledge and understanding increase so the questions make increasing use of previous work and this is also true of the A2 course work. By the second year you should understand ‘how science works’ and be able to apply these principles to new situations.

 

The Department

Jaimie Tarrell and Adam Johnstone, who have similar and complementary styles and are highly experienced tutors, will teach you in small groups. Outside of class Jaimie organises environmental awareness courses and mountain biking at the College, and Adam has written a widely used revision guide and contributes to the education programme of the European Space Agency.

 

In addition to all the usual materials necessary for running assessment practicals, we have data-logging equipment linked to state of the art computers. As well as allowing students to measure accurately changing conditions in laboratory based experiments, the equipment is robust enough to take out into the 'field' so that variables such as O2 and pH can be measured against such variables as light intensity. This produces very good data for exam projects.

Results       

We consistently achieve between 85% and 92% A and B grades at the A2 level.

Higher Education

 A large proportion of our ex-students are now practising doctors, vets or dentists. Many Biologists go on to study Marine Biology, Biotechnology, Pathology Toxicology and Pharmacology. The top universities and employers are looking for a science A level as an indication of analytical skills; so quite a few of our students go on to study Economics and Business Studies. As everyone becomes aware of climate change, there is also a growing interest in degree courses on Environmental Sciences. Biology A level is an essential entry requirement for all these courses. So if you want to save the planet and/or make money Biology is the key to unlocking your academic and professional potential.
