A Detailed Lesson Plan in Science 7I. Learning Objectives: Competency: Describe ways of using Earth’s resources wisely Objectives: At the end of the lesson, the students will be able to: A. Identify the natural resurces found in the Philippines based on the video presentation; B. Explain the effects of some human activities on natural resources using the situation given; C. Share their insights on ways to reduce the effects of human activities through class discussion. II. Subject Matter Topic/Lesson: Philippine Natural Resources References: Science 7 Manual, Quarters 3 and 4, DepEd, pp. 86-104 Integrated Science: Science and Technology Textbook for First Year, DepEd, pp. Geography and Natural Resources of the Philippines by Domingo Salita,1997, pp. 78-92 Instructional Materials: Audiovisual set (laptop, projector and speakers), title banner, illustrations and diagrams, envelope, cartolina paper, pentel pen marker III. Strategy/Procedure Teacher’s Activity A. Preliminary Activities Learner’s Activity May we all stand for the prayer. Who can lead the prayer? (A student lead the prayer) Good morning class! Good morning sir! You may now take your seat. Thank you sir. Let me check the attendance first. Make sure that you are in your proper seats so that you will not be marked absent. (Check attendance using a seat plan) Very Good! Everybody is present. B. Review of the Past Lesson Do you still remember our lesson last meeting? What had we discussed? Yes sir. We have discussed on using latitude and longitude in locating places on Earth. Yes. Exactly! We made use of latitude and longitude in locating different places on Earth. What is the relationship between the latitude of a place and the climate it experiences? The closer the latitude to the equator, the warmer the climate and the closer it is to the poles, the colder the climate they experience. Very Good! C. Motivation To start our new lesson, I will be showing you a video of the beauty and splendor of the Philippines. And now, just sit back, relax and let me take you to a tour around the Philippine Archipelago. (Show video presentation about the physical features and varied life forms in the Philippines) D. Presentation / Discussion What are the things you have observed in the video? Yes! Exactly. Our country is bountiful in natural resources starting from varied physical features down We were able to explore the different rich natural to the diverse plant and animal forms. resources found in the Philippine Archipelago. Talking about how lucky we are in the Philippines to have such things, what can you associate with the word “resources”? Yes? These are the things that are available around us which we use for different purposes. Good. How about another idea. Resources are things that can be used to support, help, or drawn on when needed. Exactly. Based on your answers, we can define resources as things used by people in order to survive or satisfy needs. Anybody who wants to give examples of resources? Very Good! (student answer varies) e.g., air, water, plants, animals, soil, rocks, minerals, crude oil, and other fossil fuels, sunlight, wind, car, house, clothes, jewelry, money, etc. Resources such as air, water, plants, animals, soil, rocks, minerals, crude oil, and other fossil fuels, sunlight, and wind are considered as natural resources because they are already available in the nature. Very Good! Now, since we are talking about resources, Philippines as an archipelago, is considered to be rich in natural resources! Let’s name out the natural resources of our country. We are blessed with the presence of different water forms. What are these water forms Bays, rivers, lakes, falls, gulfs, straits and swamps. What is the importance of these water forms? These bodies of water support the survival of diverse organisms for food as well as for economic activities. Precisely. The presence of water in a specific environment is said to be accountable for supporting high biodiversity in that area. Biodiversity means the presence various plants and animal life in a particular habitat. Can we name some of the plants and animals we can find in our country? (students answer will vary) Those species that you have mentioned are all common. Since our country is rich also in biodiversity, Philippines is considered to be the home of endemic species. When we say endemic species, these are species which can be found only in a certain area and not in any other places. What endemic species do you know which exist only Tamaraw, tarsier, Mouse deer (Pilandok) in the Philippines? Where can we find them? Tamaraw in Mindoro, Tarsier in Bohol and Mouse Deer or Pilandok in Palawan (etc.) Good! We also have mineral deposits in the country. What are the minerals that you know? (students answer may vary) Gold, Copper, Chromite, Iron, Manganese, Nickel, Sand, Limestone, Marble, Clay, Silica, etc. Where are these minerals located or can be found? Some are found near volcanoes, in rocks and near rivers, beaches etc. Philippine mineral deposits are classified as either metallic or non-metalllic. Gold, Copper, Chromite, Iron, Manganese and Nickel are some of the metallic minerals we have while Sand, Limestone, Marble, Clay, and Silica are some of the non-metallic minerals we have in our country. Where do we usually use metals? We use metals in softdrink industry, at home, in school, farm, and other places. Yes indeed. Mineral deposits can be found were volcanoes or trenches are present. We have many volcanoes in the Philippines and most of them are active. Can you name some of the famous volcanoes? (Answers may vary) Mt. Mayon, Mt. Pinatubo Because of the presence of numerous volcanoes in our place, our country belongs to the “Pacific Ring of Fire”. Aside from that we also have energy resources. What are some of these energy resources? We have solar energy, geothermal energy, hydrothermal energy, wind energy and natural gas. Do we have examples of the energy resources in our place? Geothermal Energy Plant at Puhagan, Valencia Very Good! E. Practice We have already familiarized ourselves with the natural resources we have in our country. Today, we are going to brainstorm on how people destroy natural resources. Now, I want everybody to group themselves according to your monitorial group in the class. (Students are starting to form their group) Group 1 will saty here in front at the right corner, group 2 here in front at the center, group 3 here in front at the left corner, group 4 at the back left corner, group 5 will be at the back center, and group 6 at the back right corner. In the count of five, you should be sitted with your group.(1, 2, 3, 4, 5) Ok. Everybody settle down. Now that you are with your group, you use a leader, secretary and two representative or reporters. Listen to the instruction. I be showing you some illustrations. You will be shown a “Before” and “After” of a certain situation or activities. Afterwards, you are going to determine the effects of these activities to our natural resources. Take note of the group number in the illustration. Each group have their own assigned situation based on the illustration. Did you get it? Yes sir. I will be giving first this envelope with a cartolina and pen inside. On the cartolina, there is a column for human activity that is written and on the other column (students will open the envelope) is the effects. You are going to write down the effects on the cartolina provided under “Effects”. A leader or member of the group will present their work in the class. You are going to discuss the human activities and its effects in front of the class. Now read the human activities that is assigned to your group. Lets start. (Present “Before” and “After” of a certain situation or activities in PPT) Before Group 1 After Human Activity When roads are built, mountains are blown off using dynamite. Group 2 Ricefields are turned into residential or commercial centers. Group 3 People cut too many trees for lumber or paper or building houses. Effects Group 4 More factories are being built to keep up with the demands of a fast growing population & industrialization Group 5 Too much mining & quarrying for the porpuse of getting precious metals & gravel/stone Group 6 Plastics and other garbage are thrown on the rivers and other bodies of water Now that you already visualize the way people destroy natural resources, you can now start writing down the effects. Let’s do this for 10 minutes. (Students perform the activity) After Performing Activity… May I request all groups to paste their work on the board. Group Report Anybody who has a question to the group? As we can see, nature provided us with the rich natural (Somebody from other groups will ask the reporter) resources which are of great benefit to us. In return, let us protect and conserve the richness of the country’s natural resources. IV. Evaluation Direction: On a one fourth (1/4) sheet of paper, answer the question below with a brief answer. 1. Since many of the resources that we have today are not in endless supply, as a student in what way can you help conserve and protect our natural resources? V. Assignment Make a slogan showing how to protect and conserve our natural resources. Put it in a ¼ cartolina of any color. Design your slogan artistically and make it presentable to the class. Deadline for the submission of slogan will be on Monday, June 1, 2015. Prepared by: Pablo A. Ragay Jr. BSED-IV Biological Science Negros Oriental State University
