Presentation Transcript

  1. Access Prior Knowledge Lesson 2: What are other energy sources? Opening Activity Open Science textbook to page 306. Open Science workbook to page 100A to review home learning. Open Science folder to review vocabulary words and outline for the chapter. Open Science journal and answer the following question: 1. Give an example of a renewable and nonrenewable resource and explain how we use it in everyday life. Review Content Cards and Q-Cards in bin, sharing with partners quizzing each other 
quietly. Log in to clickers using student ID number. Be ready to review home learning when timer goes off. Don't forget to write your 
home learning in your 
agenda page 101A.

  2. Do you agree with the statement? 1 Energy from sunlight can be used for heat and electricity. Yes No

  3. Do you agree with the statement? 2 The power of wind is used to turn turbines and create electricity. Yes No

  4. Do you agree with the statement? 3 Hydroelectric power plants pollute. Yes No

  5. Do you agree with the statement? 4 Geothermal energy can make electricity only during the evening hours. Yes No

  6. Solar Energy Solar energyis energy from sunlight and uses solar 
cells use sunlight to make electricity. Solar energy is renewable and it does not pollute the 
environment. But we cannot get solar energy at night or on cloudy 
days, that is why we use it in a limited way. 1. Also, changing solar energy into electricity is 
expensive and can also create dangerous wastes. Second paragraph pg. 306

  7. Wind Energy Wind turbines are used to change wind energy into 
electricity and do not cause pollution. 1. The speed of the blades does not have anything to do with 
how much energy it produces, but wind turbines spin faster in 
light winds than old windmills did. 2. Some disadvantages are the wind does not blow all the 
time and birds can die if they fly into the turbines. First paragraph pg. 308

  8. Moving Water Hydroelectricpower plants use moving water to make 
electricity and usually built in dams. 1. Parts of generators spin as water moves through the 
dam. As they spin, they make electricity. Hydroelectric plants do not use fuel to make electricity 
so they do not create pollution, and factories were built 
near rivers to use the moving water. 1. The area also has to have a place where a lake can 
form behind a dam. These lakes flood animal and plant 
habitats and can also harm fish. First paragraph pg. 310

  9. Nuclear Energy Nuclear power uses hot uranium to make steam, 
which makes electricity. 1. Nuclear power plants use less fuel than power plants 
that use coal or oil and they do not produce smoke. 2. Nuclear power plants are expensive to build, they 
make harmful wastes and uranium is a rare metal and a 
nonrenewable energy source. Second paragraph pg. 312

  10. Geothermal Energy Geothermalenergy is made from high 
temperatures inside the Earth. 1. One way this energy is used is to pour water 
down deep holes into hot rock so that hot water or 
steam rushes to the surface to make electricity. 2. Geothermal energy can make electricity all day, 
all night and can be used all year long. 3. But geothermal energy can only be made in 
places close to the surface of the Earth and the 
steam can also cause pollution. Fourth paragraph pg. 312

  11. Energy of Biomass Biomassis material that was recently 
alive usually found in garbage, which 
we will always have, therefore it is 
renewable. Biomass is burned to make 
electricity, so it does make air 
pollution. First paragraph pg. 313 Wind Energy

  12. MatchQuest Moving Water Nuclear Energy Geothermal Energy Energy of Biomass Solar Energy Wind Energy

  13. TextQuest 1. How do the speed of the blades impact the amount of energy is 
produced in a windmill? 2. What is a disadvantage of using solar energy? 3. How do hydroelectric power plants work? 4. What are some advantages of geothermal and wind energy? 5. Solar panels collect what kind of energy? 6. What material does nuclear energy require? Don't forget to write your
