# Emmanuel College Year 8 Science Exam Revision 2024 ## Exam Information * **Examination Date:** See Exam Timetable * **Topics Covered:** * Term 3: Cells, Body Systems * Term 4: Physical and Chemical Changes * **Duration of Exam:** 60 minutes (with 5 minutes reading time) * **Equipment:** You must bring a black/blue pen, pencil, eraser, ruler. Answers should be written in pen, diagrams drawn in pencil * **Content:** The examination will consist of multiple choice, short answer and extended response questions. ## Revision Guidelines 1. Print off study timetable and complete to indicate which day/night you will designate to which subject to ensure you are preparing yourself for the upcoming exams. Hang this somewhere that reminds you of the preparation you need to do. 2. Use the "Key areas” and “You should be able to" sections under each topic (in the pages that follow) to generate summaries. * Your summary notes should include: * Key definitions/ glossary words * Useful diagrams with labels * Helpful hints for remembering things * Simple explanations of important concepts using the glossary words. 3. Complete the revision questions to test your understanding. 4. Also use past topic tests/revision sheets to review your understanding. 5. Online program: Quizlet for those that like online creativity (can be shared amongst peers). ## Term 3: Cells ### Key Areas Covered: * Cell Theory * Plant and Animal Cells * Microscopes * Organelles * Bacteria and Fungal Cells ### Glossary Terms: * Binary fission, Binocular, Cell, Cell membrane, Cell theory, Chlorophyll, Chloroplast, Compound light microscope, Cytoplasm, DNA, Electron microscope, Eukaryotic cell, Eyepiece, Infectious disease, Microbes, Microbiology, Micro-organism, Microscope, Microscopy, Mitochondrion, Monocular, Multicellular, Natural flora, Nucleus, Objective lens, Organelle, Pathogen, Photosynthesis, Prokaryotic cell, Ribosome, Single-celled, Stain, Stereomicroscope, Surface area to volume ratio, Symptoms, Unicellular ### Learning Intentions: * Explain the key concepts of the cell theory and describe the surface area to volume ratio. * Compare and contrast electron microscopes and light microscopes, and stereomicroscopes and compound light microscopes. * Calculate magnification and demonstrate the ability to focus a compound light microscope. * Describe the functions of the cell membrane, cytoplasm, DNA, mitochondria, ribosomes, chloroplasts and vesicles. * Describe the key differences between natural flora and pathogens. * Explain the benefits of natural flora to human health. * Describe the development of penicillin and explain the problems associated with the overuse of antibiotics. ##
