KS3 Curriculum Guide - Year 8 Science
Term 1Matter & Organisms   
Matter - 1. Periodic Table 2. Elements Students will be looking at the physical properties of Group 1 & 7 elements. They will also learn about the structure of atoms and how to write chemical formulae of compounds. Organisms - 1. Breathing 2. Digestion Building on from cells in YR 7, students will focus on the respiratory system and learn how gas exchange occurs. They will then look at the digestive system and how food is broken down by different enzymes. Students will also evaluate the effects of an unbalanced diet.
Assessment: Matter - 30 minute end of topic test covering: Atoms, Elements, Compounds, The Periodic Table, Group 1, Group 7, Group 0, Chemical Equations. Organisms - 30 minute end of topic test covering: Respiratory System, Breathing & Respiration, Circulatory System, Effects of Exercise & Smoking, Food Groups, Diets, The Digestive System.Key Words and Terms
Term 2Reactions & Waves   
Reactions - 1. Chemical Energy 2. Types of Reaction This unit extends on the work learnt in YR 7 by looking at the energy changes in chemical reactions. Thermal combustion and decomposition will also be introduced in this unit. Waves - 1. Wave Effects 2. Wave Properties This unit continues from the waves topic learnt in YR 7 and looks at the effect of waves in various pieces of equipment and living cells. Students will also further extend their knowledge on the properties of waves.
Assessment: Reactions - 30 minute end of topic test covering: Chemical & Physical Reactions, Compounds, Combustion, Exothermic & Endothermic Reactions, Catalysts, Bonding. Waves - 30 minute end of topic test covering: Wave Properties, Ultrasound, Ultraviolet Radiation, Speakers. Key Words and Terms
Term 3Electromagnets & Genes   
Electromagnets - 1. Electromagnets 2. Magnetism Using their knowledge from YR 7, students will learn how an electromagnet can be made and how to change its strength. Students will then use the idea of field lines to show how the direction or strength of the field around a magnet. Genes - 1. Evolution 2. Inheritance Extending from the topic on Variation in YR 7, students will evaluate the evidence for evolution. They will learn how genes are inherited and how a change in the DNA may affect an organism and its offspring.
Assessment: Electromagnets - 30 minute end of topic test covering: Magnets and Electromagnets. Genes - 30 minute end of topic test covering: Populations, Food Chains & Food Webs, Extinction & Evolution, Genes & Inheritance, and Cloning.Key Words and Terms
Term 4Earth & Energy   
Earth - 1. Climate 2. Earth Resources Continuing from the structure of the Earth in YR 7, students will learn about the carbon cycle and evaluate the impacts that global warming has on the earth. Students will research how to extract and recycle materials. Energy - 1. Work 2. Heating & Cooling This unit requires students to understand how levers work and compare the work needed to move objects. They will expand their knowledge of energy to explain how heat is transferred and how temperature changes when objects are heated or cooled.
Assessment: Earth - 30 minute end of topic test covering: Fossil Fuels, Greenhouse Effect, Carbon Cycle, Metal Ores, Electrolysis, Recycling. Energy - 30 minute end of topic test covering: Work Done, Levers, Displacement, Conductors & Insulators, Conduction, Convection, Radiation.Key Words and Terms
Term 5Forces & Ecosystems   
Forces - 1. Contact Forces 2. Pressure This topic extends on the work on forces completed in YR 7 looking at concepts such as contact and non-contact forces, and how materials behave when they are stretched or squashed. Students will then go on to explain how fluids behave under pressure. Ecosystems - 1. Respiration 2. Photosynthesis Students will compare aerobic and anaerobic respiration. They will then learn how photosynthesis takes place and analyse what conditions can affect the rate of photosynthesis.
Assessment: Ecosystems - 30 minute end of topic test covering: Aerobic & Anaerobic Respiration, Yeast Fermentation, Photosynthesis, Stomata, Plant Adaptations. Forces - 30 minute end of topic test covering: Balanced Forces, Resultant Force, Friction, Hooke’s Law, Upthrust, Pressure, Motion.Key Words and Terms
Term 6Revision/Exam/Scientific Skills & Science Project   
Students will revise everything they have learnt this year in preparation for their end of year exam.
