Year 8 Science Course 2 2017 Term 4: Physical Science Text: Oxford Science 9 Physical Science Content Descriptions Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems (ACSSU155) • recognising that kinetic energy is the energy possessed by moving bodies • recognising that potential energy is stored energy, such as gravitational, chemical and elastic energy • investigating different forms of energy in terms of the effects they cause, such as gravitational potential causing objects to fall and heat energy transferred between materials that have a different temperature • recognising that heat energy is often produced as a by-product of energy transfer, such as brakes on a car and light globes • using flow diagrams to illustrate changes between different forms of energy Wk 1 2 Topic Unit 3 Intro. ENERGY and recap on SIS skills Pendulum Investigation Content General overview of types of energy – link with forces Scientific Investigation: Pendulum and Length, while recognising the constant interchange of gravitational potential energy and kinetic energy Activities Spider diagrams to establish prior learning – energy and forces. ICT exercise – find appropriate diagrams and label them to identify where each energy type and force is being demonstrated. Plan, Conduct, Analyse Data and Evaluate Investigation Resources and Experiments Pendulum bobs, 1.1 m length of thread, metre rules, stopwatches Assessment and Homework Investigation Write Up: Due Week 3 3 Unit 3.1: Energy Transferring Energy Unit 3.2 & 3.3: potential & kinetic energy 4 Unit 3.4 & 3.5 Transforming energy 5 Definitions and units: Energy measured in joules (J), weight (a force) measured in newtons (N) Where energy comes from/goes to. Specific Types of Energy – Light, Sound, Heat, Chemical, Electrical, Nuclear, Definitions and units: Energy measured in joules (J), weight (a force) measured in newtons (N) Specific Types of Energy – Mechanical (Kinetic and Potential Energy – gravitational, elastic and magnetic) Energy can be transformed. Energy can’t be created or destroyed. Links with SHE.
