Secondary Biology FORM One Students’ Book is a well written biology book that aims at equipping students with knowledge, attitudes and skills that can enable them exploit the environment responsibly. It is the first book in the secondary biology series . The book has been updated to match current trends in method of classification and other advances in the sciences. The system of naming chemical substances has also been standardised.
The content is in five broad topics namely:
Each topic is introduced in simple and precise language and is tied to the knowledge of basic science taught earlier in the primary cycle. To enhance understanding of terminologies, each is explained before use. Emerging issues such as environmental conservation are also dealt with where they are relevant. Neat and precise illustrations have been widely used to enhance learning. Practical activities are outlined at the end of each topic. These are designed to assist the learner conduct investigations in various discussion points and draw deductions. Also, at the end of each topic there are revision questions that assist the learners to evaluate themselves. Answers to these questions are provided in the accompanying Teachers’ Guide.
