Activities include matching energy types to definitions, judging statements as true or false, explaining renewable versus non-renewable energy, classifying energy sources, and completing a text on the negative consequences of fossil-fuel use using target vocabulary. The document also covers temperature effects on matter, heat transfer with conductors and insulators, light behaviors (reflection, refraction, transparency), and basic sound properties.","1. Match each type of energy with its definition.\nMechanical energy ●\nLight energy ●\nNuclear energy ●\nHeat energy ●\nChemical energy ●\nElectrical energy ●\n● It is the energy that is emitted by lightning and bodies like the Sun.\n● It is the energy that is emitted by bodies like the Sun, fire or the lava of a volcano.\n● It is the energy that is stored in substances like the food we eat and fuels like oil and coal.\n● It is the energy that is associated with the presence and motion of electrical charges.\n● It is the energy that is associated with the motion and position of an object.\n● It is the energy in the nucleus of an atom.\n2. Write True (T) or False (F).\n●\nEnergy has mass.\n●\nEnergy occupies no space.\n●\nElectrical energy is transformed into heat energy in a fan.\n●\nEnergy can transfer from one body to another.\n●\nElectrical energy can be transported through cables.\n3.  Explain the difference between renewable and non-renewable energy.\n4.  Classify the energy sources in the table below.\nbiomass, petrol, geothermal energy, uranium, hydroelectric energy, coal, tidal energy, gas\n5. Complete the text about the negative consequences of energy production. Use the words in the box.\nwarming, spills, erosion, quarries, carbon dioxide, waste, mines\nThe burning of fossil fuels releases                     into the atmosphere and causes global                     . Oil                      from tankers and industrial                      contaminate the sea and kill aquatic organisms. Taking rocks from                      and minerals from                      contaminates the land and causes soil\n.\n6. Name four things we can do to create a sustainable future for our planet.\n7. Write the names of the effects of changes in temperature on matter.\n●\nA change in volume that takes place when air cools down.\n●\nA change in state that takes place when air cools down.\n●\nA change in volume that takes place when air is heated.\n●\nA change in state that takes place when a solid is heated.\n8.  Write True (T) or False (F).\n●\nHeat always travels from the warmer body to the colder one.\n●\nThermal insulators allow heat to travel quickly.\n●\nThermal conductors do not let heat pass through them easily.\n9. Match this words with the definition.\nTranslucent material ●\nReflection ●\nTransparent material ●\nRefraction ●\nOpaque material ●\n● The change of direction that occurs when light hits an object.\n● The change of direction that occurs when light passes from one medium to another.\n● Does not allow light to pass through it.\n● Allows light to pass through it but disperses the light.\n● Allows light to pass through it without dispersing.\n10. Name the type of lens in each picture.\nlens\nlens\n11. Read the sentences about sound. Write True (T) or False (F).\nA violin has a high pitch and a double bass has a low pitch.\nSound travels more slowly through the ground than the air.\nSound is produced by the vibration of bodies.\nSound cannot travel through water.\n12.  When you pull off a polyester jumper, your hair sticks up. Explain what makes this happen.\n13.  Explain what happens to an electrical device if you put an insulator in a circuit.\n14. Label the picture.\n15. Match each word with its definition.\nHeat ●\nLight ●\nSound ●\n● It is a form of energy that travels in straight line at great speed.\n● It is the transfer of energy between two bodies that are at different temperatures.\n●It is a form of energy that is produced by the vibration of bodies","cbCaikTh4YoS3Tlm","https://ap.wps.com/l/cbCaikTh4YoS3Tlm","docx",1729531,1,5,"English","en",105,"# Energy and Definitions\n## Renewable vs Non-renewable\n## Negative Effects of Energy Production\n# Heat and Temperature Changes\n# Light: Transparency and Optical Effects\n# Sound: Properties and Statements","[{\"question\":\"What are the differences between renewable and non-renewable energy?\",\"answer\":\"Renewable energy comes from sources that can be replaced naturally over time, while non-renewable energy comes from sources that take a very long time to form and will eventually run out.\"},{\"question\":\"How do thermal conductors and thermal insulators affect heat transfer?\",\"answer\":\"Thermal conductors allow heat to pass through more easily, while thermal insulators do not let heat travel quickly.\"},{\"question\":\"What happens when light hits an object and when it moves between different media?\",\"answer\":\"When light hits an object, it can change direction through reflection.
