Title: Protection and Conservation of Natural Resources Learning Competency:Cite and explain ways of using Earth’s resources sustainably S7ES-IVc-4 II. Instructions: This activity sheet focused about Earth’s resources and how to use them sustainably. Below are the activities with regard to this topic. Read the directions of every activity and answer what is asked. III. Activities Activity 1 Nonrenewable Resources A nonrenewable resource is a substance that is being used up more quickly than it can replace itself. Its supply is finite or available only in limited amount. A. Directions: Check the blank if you think the resource is nonrenewable. ___ coal ____wind/air ____solar energy ___petroleum ____plants ____biogas ___natural gas ____nuclear energy ____natural oil ___water ____minerals/metals ____animals ____geothermal energy B. Directions: Identify the nonrenewable resource being described. _____1. It comes from remains of plants and animals that died hundreds of millions years ago. It has the highest level of carbon of all fossil fuels _____2. also known as petroleum. Can be extracted and refined to make products such as gasoline, diesel, and jet fuel. It also a kind of fossil fuel _____3. a kind of fossil fuel formed from the remains of tiny sea plants and animals that died millions of years ago. It is mainly composed of methane. _____4. A process to produced electricity through nuclear fission. It gets raw materials from radioactive elements like uranium and these elements are nonrenewable. _____5. Formed by long-term geological processes deep within the Earth’s crust and are often costly to mine. Activity 2 Renewable resources A natural resource which can be used repeatedly and replaced naturally. It can replenish itself at the rate it is used. A. Directions: Check the blank if you think the resource is renewable. ___ coal ____wind/air ____solar energy ___petroleum ____plants ____biogas ___natural gas ___water ____nuclear energy ____minerals/metals ____geothermal energy ____natural oil ____animals B. Directions: Identify the renewable resource being described. _____1. They can be harvested and planted by humans or they can naturally reproduce as they drop seedlings and germinate on their own. _____2. Food sources such as chicken and tilapia. They can also be grown to supply its demand. _____3. It serves as a drinking resource and also generates hydropower necessity. _____4. It is the source of the oxygen animals and humans breathe and also a source of other gases needed by organisms.This can also be used for energy generation. _____5. Gas such as methane which can be harnessed from manure. _____6. It is made from palm oil, vegetable oil, sunflower oil soybean which can all be used to make biodiesel. _____7. It is harnessed from the sun which can be a source to generate electrical energy. _____8. It supplies electricity by powering electrical generators with the heat of the earth and naturally occuring subterranean hot water reservoirs. Activity 3: Using Earth’s resources sustainably Earth’s natural resources supply the needs of living organisms everyday. People depend on natural resources for just about everything that keeps them fed and sheltered as well as the things that keep them entertained. Take note also that nonrenewable resources are finite, so sustainable measures should be taken to ensure that they last. Also, some of the renewable resources may become nonrenewable if their usage is not manage properly. They should be used wisely so future generations can still enjoy them. Sustainable resource use occurs when the rate of consumption can continue forever without damaging the environment. Directions: Write “S” if the sentences describe a sustainable way of using a natural resource and write “NS” if the sentence describe a not sustainable way of using Earth’s resource. Write your answers on the blanks. ______1. Mang Ruben uses fishnets with little holes and dynamites when fishing. ______2. The office’s electricity is generated from solar panels instead of using electricity generated from fossil fuels. ______3.Hunting of wild animals and endangered species is encourage by the government. ______4. Lina’s family wanted to plant falcata. In clearing the mountain, they used slash and burn or kaingin. ______5. Nikki and her mother plants vegetable on their backyard. That way, they will have fresh and healthy food. ______6. Mario does not close the faucet when he is brushing his teeth. ______7. Juan’s mother always remind them to unplug the TV, electric fan, and other devices when they are done using them. ______8. Gina’s family lives in the farm. They have chickens, ducks, goats, and pigs. They sell some of them and also consume some as their food. ______9. Schools encourages reducing, reusing, and recycling of materials to lessen or cut back the amount of raw resources. ______10. Ben rides his bicycle to school instead of using his motorcycle or taking a tricycle. IV. How Much Have You Learned? A. Compare and Contrast Renewable and Nonrenewable resources using a venn diagram. Renewable resource Nonrenewable resource B. Complete the table below. State the effects of the following activities to natural resources. Some are completed as an example. (Source: Grade 7 Science Learner’s module) Activities When roads are built, mountains are blown off using dynamite. Some farmers use too much chemical fertilizers to replenish soil fertility. Rice fields are turned into residential or commercial centers. People cut too many for lumber or paper or building houses More factories are being built to keep up witht he demands of a fast growing population and industrialization. Effects on Natural Resources Damage natural habitats and/or kill plants and animals. Too much fertilizer destroys the quality of the soil and is harmful to both human and animals. Too much mining and quarrying for the purpose of getting precious metal, stones, and gravel Plastics and other garbage are burned Cars, trucks,and tricycles that emit dark smoke are allowed to travel C. Explain why sustainable use of resources should be done and cite specific examples of sustainable resource use. _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ Prepared by: DIANNAH M.
