Energy II Packet... Energy II Packet...
Warm up... 1. The energy on Earth originated from the a. Moon d. ??? b. Space c. Sun 2. On Earth, energy can be destroyed. a. True b. False 3. A ________ is any device that converts energy. a. Machine b. Toy c. Gadget
Nonrenewable resources are those energy resources that are in limited supply They cannot be replaced in short time periods
Renewable resources can be replaced in relatively short times They are in "limitless" supply
Read your textbooks Complete the Energy Resources Chart & Questions -Soft cover book: pages 16-25 -Hard cover book: pages 134-139
Fossil Fuels are formed from dead organisms Plants and animals that die still have chemical energy left in their bodies Petroleum, coal, natural gas
Radioactive elements release nuclear energy Fission Dangerous waste is produced
Hydroelectric energy is when water converts potential energy to kinetic when it moves
Biomass is the stored chemical energy in living things Living materials can be burned to release energy
Geothermal is the thermal energy found in the heat below the Earth's surface
Explanation Advantages Disadvantages Examples Geothermal Thermal energy from the earth Limitless Requires little land Only practical near hotspots Water pollution Iceland Fossil Fuels Energy from things that were living and died millions of years ago Large amounts of energy Easy to transport Nonrenewable Smog Risk of spills Coal, oil, natural gas Water Potential energy from running water Renewable No air pollution Dams disrupt ecosystems Only avail. @rivers Wind Only practical where windy Currents of air caused by sun heating earth Renewable No air pollution Inexpensive Solar Sunlight converted to electricity No pollution limitless Expensive Only practical where sunny Biomass Energy stored in living things Renewable Requires farmland Smoke Wood, Plant materials, corn
Warm up... 1. What energy resource is most interesting to you? 2. Complete the Energy Resources Critical Thinking Page
Jouleville Your group will... Research the resource What is it? What are the pros to using it? What are the cons to using it? How common is this resource? Prepare an argument Why is this the best? Why are the others not as good? Present your argument Use a visual
Warm up... 1. Take out ALL conference materials Notes Required pages Choice pages 2. Put your name on EVERY page 3.Get started on Jouleville with your group
Jouleville Your group will... Research the resource Prepare an argument Prepare your visual
Warm up... 1. Find the GREEN exam review sheet 2. Look over the sheet and either review/study the answers you already have or work on the ones you don't have
Jouleville Your group will... Finish your argument & visual Finish your works cited Practice
