The course comprises lots of relevant practical work from dissection of fish gills to looking at the ultrastructure of cells using microscopy. Theory sessions will include the digestive system, gas exchange in the lungs and in other organisms, immunology and heart disease. You will also study the growth of populations in different countries, photosynthesis, nerves, muscles and cutting edge DNA technologies. You will attend a one week field course residential at a Field Studies Centre in The Lake District in June of the lower sixth. This will be an intensive week of work out in the field where you will learn about field work, populations and the factors affecting their distribution. Key topics include: • Biological molecules • Cells • Organisms exchange substances with their environment • Genetic information, variation and relationships between organisms • Energy transfers in and between organisms • Organisms respond to changes in their internal and external environments • Genetics, populations, evolution and ecosystems • The control of gene expression
