2. Energy Resources & The Sun  To be able to explain why most energy resources originate from the sun Friday, March 11, 2016

3. Energy  Fill in the missing words using the energy key words worksheet

4. Energy

5. Energy Origins Where does the energy we use come from?! Nearly all the energy we use originally came from the Sun Where does the energy we use come from?! Nearly all the energy we use originally came from the Sun. The sun is the original source of most energy resources

6. Sun coal wind biomass oil The Sun is the original source of most energy resources. natural gas food waves

7. Sun Origins  Heat and light from the Sun provide us with energy directly  Plants also store the Sun’s energy through photosynthesis (utilising light to make sugar from carbon dioxide and water)  Coal, oil and natural gas were formed from the remains of dead plants and animals (the energy in these fuels came from the bodies of the plants and animals)  The animals got their energy from the plants they ate, and the plants got their energy from the Sun!  Heat and light from the Sun provide us with energy directly  Plants also store the Sun’s energy through photosynthesis (utilising light to make sugar from carbon dioxide and water)  Coal, oil and natural gas were formed from the remains of dead plants and animals (the energy in these fuels came from the bodies of the plants and animals)  The animals got their energy from the plants they ate, and the plants got their energy from the Sun!

9. Sun Origins  Solar power utilises sunlight directly  Wind is caused by the Sun heating up the Earth (convection currents)  Waves are caused by the build up of this wind  Hydroelectric power relies on water movement (which fell as rain after being evaporated by the Sun’s energy)  *Only tidal energy (caused by the Sun and Moon’s gravity); nuclear energy (energy stored within uranium); and geothermal energy (heat from the Earth) do not originate in the Sun!  Solar power utilises sunlight directly  Wind is caused by the Sun heating up the Earth (convection currents)  Waves are caused by the build up of this wind  Hydroelectric power relies on water movement (which fell as rain after being evaporated by the Sun’s energy)  *Only tidal energy (caused by the Sun and Moon’s gravity); nuclear energy (energy stored within uranium); and geothermal energy (heat from the Earth) do not originate in the Sun! Tidal Power

10. Sun Energy  Complete the energy from the Sun worksheet…  When you have completed this, you may make a poster explaining how nearly all the energy we use originates from the Sun  Complete the energy from the Sun worksheet…  When you have completed this, you may make a poster explaining how nearly all the energy we use originates from the Sun

13. Not Always The Sun  Nuclear, geothermal and tidal energy to not originate from the Sun - why not?!  Nuclear power comes from the energy locked up in the nuclei of atoms (uranium)  Geothermal energy comes from heat being released within the Earth (via nuclear decay (but much slower than a nuclear power station))  Tides are caused by gravitational attractions of the Sun and Moon  Nuclear, geothermal and tidal energy to not originate from the Sun - why not?!  Nuclear power comes from the energy locked up in the nuclei of atoms (uranium)  Geothermal energy comes from heat being released within the Earth (via nuclear decay (but much slower than a nuclear power station))  Tides are caused by gravitational attractions of the Sun and Moon
