Synopsis Biology is a living science, in which changing knowledge continually generates fresh perspectives and fresh opportunities for productive impacts on our society. The knowledge of biology that has been gained, especially in the last decade, provides us with a tool of unprecedented power to improve the human condition and lessen human impact on the world we share with life’s other creatures. If biology is to be learned effectively, it must be experienced. It is so close to the life of every girl and boy that no teacher need ever be without first-hand materials for the study of biology. Basic scientific concepts such as evolution, genetics, cytology and their inter-relation, and levels of organization in living things, provide the key themes for major chapters of the book. It is designed to equip teachers and students with modern methods of teaching biology.
