Earth Science Learning Activity Sheets Quarter 1 Week 5 CONTENT: Describe how fossil fuels are formed (S11/12ES-Id-10) Day 1-4: Fossil Fuels I. Objective: At the end of this lesson, you should be able to: describe how fossil fuels are formed; and identify the advantages and disadvantages of using fossil fuels. II. Introduction: Video Analysis Activity: How Fossil Fuels are Formed? Directions: Watch the video on this YouTube link: https://www.youtube.com/watch?v=Ied4ogxqXUM and work on the following guide questions: 1. What are fossil fuels? 2. Where do fossil fuels come from? 3. Why fossil fuels are important? 4. Why fossil fuels are not sustainable? 5. What are the pros and cons of using fossil fuels? 6. Suggest ways on how to lessen the impact of the use of fossils. III. Lesson Proper: Fossil fuel is a general term used to refer to all deposits of organic materials capable of being burnt as fuels. Fossil fuel comes in the form of: o Coal o Oil and Gas Coal is a carbon-rich deposit formed from dead plant material through the process of coalification. Peat is a precursor to coal. Coal is formed due to physical and chemical modification of peat known as peatification. Ranks of Coal 1. The lowest rank of coal is lignite. It is brown in color and has an earthy, crumbly texture. 2. Sub-bituminous coal is in between lignite and bituminous. 3. Bituminous coal is a medium rank coal. Its physical characteristics are generally black, shiny, and hard. 4. Anthracite is the highest coal rank. It is shiny and has a conchoidal fracture. Oil, also known as petroleum, is a black, thick and mushy liquid. It is commonly found between rock layers. Natural gas is formed deep within the Earth. It is made out of methane, the lightest hydrocarbon. Oil and gas are recovered through drilling onshore and offshore. Drill pipes puncture through the caprocks allow the flow from reservoir to the surface. Fossil Fuel Consumption o As of 2013, the Philippines’ fossil fuel consumption is 61.25% of the total country energy consumption. Many power plants depend on coal and diesel as fuel for their equipment. Advantages of using Fossil Fuels o Many industries depend on the use of fossil fuels to power their machines and other equipment.  o Fossil fuels are very efficient. It can produce huge amounts of energy especially coal and oil. Disadvantages of using Fossil Fuels o Burning of fossil fuels produces carbon dioxide and other harmful gases which degrade the environment. o Fossil fuels cannot be renewed in short periods of time. IV. Summing up: Fossil fuel is a general term used to refer to all deposits of organic materials capable of being burnt as fuels. Coal is a carbon rich deposit formed from dead plant material through the process of coalification. Peat is considered as a precursor to coal. Oil, also known as petroleum, is a black, thick and mushy liquid. It is commonly found between rock layers. Natural gas is described as the cleanest energy alternative because it emits less harmful by-products than other fossil fuels do. V. Enrichment Activity: Flip Book Activity: Directions: Make a flip book on fossil fuels with the following foci: 1. What are fossil fuels? 2. What is a coal? 3. What is an oil? 4. What is a natural gas? 5. What are its pros and cons? Note: This will be a group activity and bring the necessary materials you would like to use to work on your flip book. VI. Multiple Choice Quiz: Directions: Choose the letter of the correct answer. 1. Correctly arrange the following types of coal in terms of increasing carbon content. A. peat B. lignite C. bituminous coal D. anthracite 2. What is the difference between coal and oil & gas? A. Coal is mined underground. Oil and gas are mined underwater. B. Coal is from remains of plants. Oil and gas are from remains of animals. C. Coal is produced only from plants. Oil and gas are produced from marine animals, aside from plants. D. Coal is rich in inorganic matter. Oil and gas are rich in both organic and inorganic matter. 3. In which of the following bodies of rock will you most likely find abundant amounts of the oil and gas? A. In the source rocks B. In the reservoir rocks C. Between the cap and source rock D. Between the source rock and reservoir rock 4. Which of the following is a disadvantage of using fossils fuels? A. hard to find B. causes air pollution C. source of health problems D. non-renewable source of energy 5. In what ways can we reduce the negative effects of using fossil fuels? A. Buy your own generator. B. Riding public transportation. C. Avoid wasting electrical energy. D. Rallying to shut down fossil power plants
