Do Now 1. Itemize each step from an energy source (gas, electricity, water) used when you get out of bed. Write 3 sentences. I take a shower- water I turn on the lights- electricity I turn on the stove- gas 2. Where does the energy come from? maybe from digging fossils, water source (dam), sun, and plants
Do Now 1.What are the steps you take after getting out of your bed and out the door? (Write a sentence on each line.) I wake up with an alarm clock. -electricity I brush my teeth and wash face. –water, electricity I get dressed. -electricity I cook bacon. –gas, electricity
5. Coal is formed after the molecules in ancient plants are heated up under pressure for millions of years. 7. used in cars and to turn on the light. 8. an energy source that is used up faster than it can be replaced.
9. pollution, acid rain and respiratory illnesses are consequences. 10. breaking apart uranium atoms. 11. nuclear to thermal to kinetic to electrical energy 12. we save on fossil fuels and gives you no air pollution
13. It can be radioactive and uranium is nonrenewable.
Do Now 1.___ include natural gas, coal and petroleum oil. 2.They are used to heat our homes, power our cars and f___. 3.Since this type of energy can not be replaced after they are gone they are called ___ resources. 4. What are the effects of burning fossil fuels? Fossil fuels actories non-renewable
4. What are the causes of burning fossil fuels? Carbon dioxide and methane: are greenhouse gases Lung problems Acid rain
Do Now 1.___ % of the global consumption uses oil, coal and natural gas. 2.What are the advantages of using fossil fuels? 3.What are the disadvantages of using fossil fuels? 4.What can we do to stop using more fossil fuels? 60 to 80
2. What are the advantages of using fossil fuels? Heating homes They are quick energy sources.
3. What are the disadvantages of using fossil fuels? pollution Non-renewable resource Destroying the land
4. What can we do to stop using more fossil fuels? Use less energy Commuting choices

2. Microorganisms like ___ buried under rocks where their bodies turned into carbon under pressure and ___. diatoms heat
3. Natural gas is lighter than ___ and is made up mostly of ___ and usually is found near petroleum. air methane
Do Now 1.Alternative resources are sources of energy that are safe and cause less harm to the ___. 2.Examples are: ___ 3.Inexhaustible resource are sources of energy that can not be used up by ___. 4. Hydroelectricity is a(n) ___ but not a(n) ___ resource since water needs to be replenished continually. (renewable, nonrenewable, alternative, inexhaustible) environment Solar and geothermal energy, wind power

Do Now 1. How does a nuclear power plant produce energy? 2. Where do the excess waste neutrons go?
1. How does a nuclear power plant produce energy? splitting It produces energy by splitting neutrons of an unstable element called uranium.
The energy we need comes from this element, having more mass than its ___. neutrons
2. Where do the excess waste neutrons go? The waste goes in underground ceramic containers.
Do Now- repeat 1.Nuclear power plant produce energy by ___ of neutrons of an unstable element called uranium. 2. The energy we need comes from this element, having more mass than its ___. 3. At a power plant the excess waste of neutrons are absorbed and contained in ceramic ___. splitting neutrons containers

Do now- E transformation and sources worksheet How fossil fuel is used as electrical energy: 1.The ___ converts dead organisms into chemical energy which is changed into fossil fuels. 2.Fossil fuels when burned turns water into steam which is then used to generate ___. sun electricity
Sources of Energy, pg 729 worksheet 4. Petroleum oil is made from the remains of dead plants who lived in Earth millions of years ago. 6. Natural gas is found when you drill to break up underneath the ground that has these remains of microscopic organisms that lived in Earth millions of years. This in turn releases natural gas for us.
11. Nuclear E of atoms=> Thermal E of water=> KE of steam=>KE of turbine => electrical E out of generator 14. Radioactive waste is sealed in ceramic containers so it wont spill and will not crack during an earthquake.
28. Photovoltaic collectors 33. A geothermal reservoir is hot water and steam that is trapped under high pressure in the Earth’s surface.
an inexhaustible resource. 36. Geothermal plant is powered by using hot water and steam produced by geothermal energy to generate electricity. 39. During the winter the air is cooler than the ground below. Then, the cool water absorbs heat from the ground and releases it into the house.
43. Steps in using Tidal E as the high tide comes in, it turns a turbine connected to a generator to make electricity. stop
Do Now- from Fuel Cell reading 1.An advantage of hydrogen-oxygen fuel cells is that astronauts can drink the ___ 2.E in a fuel cell power plant: Chemical => ___ E E in a fossil fuel burning plant: (coal formed from the sun) (heat up coal to power a factory) 3.
