Biology is the study of life on Earth. The existence of millions of different species makes the subject fascinating, but it can also make it challenging. There is so much to learn and so much that we still don’t know about organisms that exist and those that used to exist. A biologist tries to understand the living world at all levels, from the unseen microscopic to the much larger, visible organisms. They use many different methods and techniques to help them do this. 

Biology is still a young science and we expect to learn much more about it in the 21st Century. This is important because as the population increases, there will be more pressure put on our planet, its environment and its resources. 

By studying IB Biology students will become more aware of how scientists work and communicate with each other. They will carry out experiments where they will learn specific techniques, skills and knowledge that develop their ability to work within the scientific community. They will learn to ask questions and dive deeper into topics that interest them. These will not only make them better scientists overall but, hopefully, more effective learners as well.
