Year 8 EXTENSION Science IMCC 2017 Physical Sciences Physics - to be delivered in Term 4 (10th October to 7th December: 8 teaching weeks with week 9 being the Exam week) Energy appears in different forms including movement (kinetic energy), heat and potential energy, and causes change within systems (ACSSU155) Elaborations ● 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 Topic CONTENT Activities ACSSU155 General overview of types of energy – link with forces 1 Unit 5 Intro. ENERGY and recap on SIS skills 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 Pendulum Investigation 2 Unit 5.1: Energy Around You 3 Scientific Investigation: Pendulum and Length, while recognising the constant interchange of gravitational potential energy and kinetic energy ACSSU155 Definitions and units: Energy measured in joules (J), weight (a force) measured in newtons (N) Specific Types of Energy – Light, Sound, Heat, Chemical, Electrical, Nuclear, Mechanical (Kinetic and Potential Energy – gravitational, elastic and magnetic) ● Unit 5.1 Review p 175-176 q 1-16 ● Spring balances and Potential and Kinetic Energy worksheet ● Creepy Crawly Pearson Science Y8 Textbook Pg173 ● Pearson Interactive Drag and Drop: Forms of Energy ● Unit 5.1 Worksheet: Hero of the Hudson Resources and Experiments Assessment and Homework Pendulum bobs, 1.1 m length of thread, metre rules, stopwatches Investigation Write Up: Due Week 3 ● Spring balances and slotted masses ● Measure the mass and weight of common objects (pencil case, ruler, pen) ● Making Spiders Pearson Science Y8 Textbook Pg171 ● Creepy Crawly Pearson Science Y8 Textbook Pg173 ● p. 177 Making a spinning snake Investigation Validation (5%) Unit 5.1: Energy Around You cont’d 4 Unit 5.2: Energy Changes 5 Unit 5.2: Energy Changes, cont’d 6 7-8 Unit 5.3: Energy Efficient Design Revision, Exam preparation and Examination 9 ACSSU155 Consider sources of energy – non-renewable (fossil fuels and nuclear) and renewable (wave, wind, tidal, geothermal, hydroelectric, solar and biomass). Links with SHE. ACSSU155 Investigate 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 ACSSU155 Investigate different forms of heat transfer – conduction, convection and radiation ACSSU155: 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 Revise concepts from weeks 1-8 Investigate why it is important to develop renewable energy resources and how they can ‘captured’ to make useful types of energy, especially electricity and heat Energy Makes things happen Heat Transfer Hot Stuff Use flow diagrams to illustrate changes between different forms of energy Unit 5.2 Review p 185186, q 1-2 Make a ‘vacuum flask’ – try to insulate a beaker of hot water using everyday materials Content will help provide knowledge and ideas for the ‘energy efficient design’ activity in week 10.

They identify different forms of energy and describe how energy transfers and transformations cause change in simple systems. 9 10 Energy transfer through different mediums can be explained using wave and particle models They explain the concept of energy conservation and represent energy transfer and transformation within systems. They apply relationships between force, mass and acceleration to predict changes in the motion of objects. Science Understanding Physical Sciences Science as a Human Endeavour Nature and development of Science Scientific knowledge changes as new evidence becomes available, and some scientific discoveries have significantly changed people’s understanding of the world Science knowledge can develop through collaboration and connecting ideas across the disciplines of science Use and influence of Science Science and technology contribute to finding solutions to a range of Contemporary issues; these solutions may impact on other areas of society and involve ethical considerations Refer to year 7 descriptors. Scientific understanding, including models and theories, are contestable and are refined over time through a process of review by the scientific community Advances in scientific understanding often rely on developments in technology and technological advances are often linked to scientific discoveries People can use scientific knowledge to evaluate whether they should Refer to year 9 descriptors. Science understanding influences the development of practices in areas of human activity such as industry, agriculture and marine and terrestrial resource management People use understanding and skills from across the disciplines of science in their occupations accept claims, explanations or predictions Advances in science and emerging sciences and technologies can significantly affect people’s lives, including generating new career opportunities The values and needs of contemporary society can influence the focus of scientific research
