2 Major Sources of Energy (triangle foldable) *Sun:MAJOR source of energy for life on EARTHLight and heat energyWarms earth*Geothermal:Energy within EarthProduces heatCan be used for human energy needs*Nuclear:Particles inside atoms have stored energyEnergy can be released during radioactive decay, fusion, fisson.
3 Conservation of Energy (conservation of energy foldable) The Law:Energy cannot be created or destroyedWhat it means?Energy CAN NOT be made or destroyedEnergy can be Transferred or transformedExample:Energy released by food molecules during digestion converted to other forms of chemical energy, heat, and mechanical energy.
4 Energy Transformation: (foldable) Energy Transformation: (foldable) *the sun is major source for ALL living thingsLabel the following info above each picture on the foldable.Above Write:Sun image: Light EnergyTree/Dinosaur image Chemical EnergyFossil Fuel gas pump Chemical energyAutomobile (truck) Electrical energyMusic /bulb/speedometer Sound/Light/Mechanical/Heat energy(from radio, heater, headlights,engine)
5 Forms of Energy Foldable: Thermal Energy:Energy associated with temperatureHot objects have greater energy than colder objects
6 Radiant Energy by electromagnetic radiation Not just visible light Light EnergyRadiant Energy by electromagnetic radiationNot just visible lightEM radiation caddied by radio, infrared, UVwaves
7 Electrical Energy Electricity: Energy carried by charged particles Current: Charged particles that build up and move
8 Energy due to motion or position 2 kinds= Potential and Kinetic Mechanical EnergyEnergy due to motion or position2 kinds= Potential and Kinetic
9 Energy associated with NOISE Carried by sound waves Sound EnergyEnergy associated with NOISECarried by sound waves
10 (the nucleus specifically) Nuclear EnergyEnergy stored in atoms(the nucleus specifically)
11 Energy stored in chemical bonds between atoms of a substance Chemical EnergyEnergy stored in chemical bonds between atoms of a substance
12 Energy produced by solar, wind, geothermal Green EnergyEnergy produced by solar, wind, geothermalFrom natural sources that are renewable.
13 Insert these two terms UNDER your foldable Primary Energy Source:Can be used directly as appear in natural environmentEx:coal, oil, natural gas, wood, sun, windSecondary Source of Energy:From transformation of energyEx: petrol, electric, nuclear
