Integrated Science-502-1 - ECZ-2022-Past Paper

Description

Tackle your Grade 9 science revision with this official Integrated Science 502/1 past paper from the Examinations Council of Zambia (ECZ). Used in the 2022 Junior Secondary School Leaving Examination, this is an essential resource for students aiming to understand the exam's format and key topics. The paper is divided into two sections, testing a wide range of knowledge. Section A features multiple-choice questions on core concepts like the human reproductive system, diseases such as HIV/AIDS and malaria, and environmental issues including air, water, and land pollution. It also covers plant biology (phototropism), changes of state in matter, and calculations for weight, density, and pressure. Section B requires detailed written answers, delving deeper into diagram-based questions. You will find exercises on labelling the female reproductive system, identifying plant and animal cell structures, and explaining processes like distillation for water purification. The paper also tests understanding of energy forms, the principles of light and lenses, and the mechanics of breathing. This makes it an invaluable tool for reviewing practical and theoretical science. Use this past paper to practice answering questions on heat movement (conduction, convection, radiation), electric circuits, and the functions of the human heart. It's the perfect study aid to build confidence and ensure you are fully prepared for the Grade 9 Integrated Science exam.
