“Friendly Earth Biology: Questions and Answers” is a study-aid covering possible examination questions and answers on the topics prescribed in the Namibia Senior Secondary Certificate for Higher and Ordinary Level. It is designed to show learners how to interpret and answer examination questions for Biology. Learners should first familiarise themselves with the contents in “Friendly Earth Biology Grades 11 and 12” (or any other source based on the syllabus). Once they are confident that they have a firm understanding of the theory, they can test their knowledge and understanding of the content by answering the questions in this guide. The answer to each question follows immediately after the question. Learners should first read through the question, while covering the answer, where possible. Exceptions would be Graphs and Tables where answers are provided. They should discipline themselves not to read the answer before working through the question first. They can then evaluate their own work by comparing their answers to those in the book. The questions include short-answer questions, as well as objective, structured and data response questions for Higher and Ordinary Level, and paragraph questions for Higher Level (Paper 2 Section B). The questions are designed to develop scientific skills, such as observation, interpretation and application of knowledge. “Friendly Earth Biology: Questions and Answers” can also serve as a valuable tool for teachers to help reinforce and consolidate the basic knowledge required by the syllabus. It will be very helpful to markers and examiners when marking or setting examination papers, as the ticks shown throughout indicate how teachers should allocate the marks for the answers. This book provides material for classwork, homework and serves as a revision programme for “Friendly Earth Biology Grades 11 and 12”. Higher Level learners should work through all questions in this book. The same applies to Ordinary Level learners, with the exception of those questions indicated for Higher Level (HL) only.
