Biology AS & A Level at Hornsea School and Language College

Course description

Biology plays an important role in the understanding of complex forms of life involving humans, animals and plants.   Biology helps individuals understand the interaction between humanity and the world. It also develops interests in the lives of living organisms in an effort to preserve them.

The work that biologists do is vital to us all. The human genome has been sequenced and we know the complete arrangement of the three thousand million bases that make up human DNA. In Kenya 350 people die every day from AIDS and in South East Asia the skies are dark with smoke as the last Bornean   rainforests are burned to grow oil palms. Biologists are concerned with all these issues. They work in the fields of cell biology, medicine, food   production and ecology.

Biology is a fascinating subject which involves the study of a wide range of exciting topics, ranging from molecular biology to the study of ecosystems. The course includes both theoretical and   practical lessons, with plenty of opportunity to devise, complete and analyse investigations including dissection techniques. Two of the ecological investigations are undertaken on fieldwork trips.

The skills and some subject content are transferrable to other A- level subjects  especially Chemistry, Physical Education and Geography.
