ScienceDate: Aug. 27, 2013I.Objective: Describe the effects of deforestationII. Subject Matter: Deforestation Ref. Into the Future:Science and Health 6 pp. 80-83 EPOW pp, 128-129 Science Spectrum pp 98-99 Materials: picture of a forest Science Concepts: Forests are hugely important for life on earth. This is because it serves as an ecosystem, and sustains life for millions of animals, birds and animals that live in the rivers and streams running through these forests. It also does a lot of good to the atmosphere in climate control as well as supplying oxygen for human sustenance.III. ProcedureA. Preparation1. Review: Importance of the Forest2. Review Drill about the importance of the forest3. Science Trivia- A forest is one of the top 5 natural resources on earthB. Developmental Activities1. Motivation: Show the layers of the forestsa. Emergent layer topmost layer where only the tallest trees can reach and where birds, butterflies, small monkeys and bats are found.b. Canopy layer layer where most trees in the forest grow. Aerial plants are also found in this layer. It is the layer that receives much sunlight. Birds, monkeys, sloths, lizards, snakes and insects live in this layer.c. Understory layer where there are vines and dense vegetation are found. There is not much sunlight in this layer.d. Forest floor dark, damp, full of dead leaves, twigs and dead plants. Little or no winds and rains reach this place.2. Presentation: Make an incomplete statement that the pupils will answer to identify the problem to be solved for the day. What might happen if _____.3. Activity/DiscussionProcedureUsing data gathered from different sources, answer the following:a. What is deforestation?b. Read the facts in the first column and fill up the incomplete sentences in the next column

I KNOW THAT ...WITHOUT TREES, I THINK ...

1. Trees and plants in the forest absorb and retain water in their roots. - flashfloods will occur in lower areas

2. Trees and plants in the forest hold the soil in place.- soil erosion and even landslide may occur

3. The forest is the habitat to millions of animals.-the animals will have no home and shelter causing them to become endangered or extinct.

4. The forest is the source of oxygen that supplies animals and man with air.-there will not be enough oxygen for animals and man to survive

5. A large part of the water that circulates in the forest ecosystem remains inside the plants. Moisture in plants is transpired into the atmosphere.- water cycle is disrupted

6. Forests serves as a water shed or water source for organisms living there.- sunlight can reach the forest floor and dries up rivers and bodies of water

7. Plants absorb carbon dioxide from the atmosphere in the process of photosynthesis.-more carbon dioxide in the air can cause global warming and climate change

8. The forest is a source of lumber, medicine and other needs of man- there would be a decrease in the sources of lumber, medicine and other needs of man.

4. GeneralizationDeforestation is when humans remove or clear large areas of forest lands for non-forest use. These include clearing for farming purposes, ranching and urban use. In these cases, trees are never re-planted. Since the industrial age, about half of worlds original forest had been destroyed and millions of animals and living things have been endangered. Effects of Deforestation see table above5. ApplicationImagine a forest which had been cleared by deforestation. Draw it in your science notebook.6. Evaluation Complete the following statements1. Trees absorb water in their roots. Without trees, _____.2. Trees release oxygen in the air to make food. Without trees, _____.3. Trees hold the soil with their roots. Without trees, _____.4. Trees absorb carbon dioxide in the air. Without trees, _____.5. Forest is the home of millions of species of animals. Because of deforestation, _____

ScienceDate: Aug. 28, 2013I. Objective: Describe the destructive effects of all types of pollution in an ecosystemII. Subject Matter: Harmful Effects of pollution Ref. Into the Future: Science and Health 6 pp. 93-95 EPOW 6 pp. 118-120 InternetIII. ProcedureA. Preparation1.Review: Deforestation2. Review DrillB. Developmental Activities 1. Motivation: Relate to the pupils the oil spill that recently happened in Cavite cause by a pipe leak of Petron 2. Presentation Present to the pupils the effect of oil spill in the marine ecosystem and the people leaving near the ocean. Ask the pupils, what kind of pollution is oil spill? Let them state the problem, What are the destructive effects of all types of pollution? 3. Activity/Discussion a. Divide yourselves into groups b. With your group mates, gather data and share ideas about the following: 1. Definition of pollution? 2. 2 examples of air pollutants 3. 2 harmful effects of air pollution

4. 2 examples of water pollutants 5. 2 harmful effects of water pollutants 6. 2 examples of land pollutants 7. 2 harmful effects of land pollution c. Answers will be discussed in class 4. Generalization Pollution is the presence of impurities on land, water and air and effects ecological balance. Pollution is a result of overpopulation, destructive practices of man and natural calamities.A. Air pollution The atmosphere helps protect the Earth from the intense heat of the sun and contains gases which allow life to exist. Making the air impure with the addition of gases or particles either by nature or human activity destroys the atmosphere. Things that pollute the air includes nitrogen oxides, carbon monoxides, hydrocarbons, sulphur dioxides, CFCs (aerosol sprays, refrigerators, air conditioners) , dust particles and organic compounds are called air pollutants. These pollutants came from factories, vehicles, burning fossils and household and farming chemicals. Effects: acid rain(nitrogen oxide and sulphur dioxide) , health problems, disrupt natural cycles and processes, destruction of ozone layer, death of plants and animalsB. Water pollution - Impurities that can affect the natural properties of water are called water pollutants. Water pollutants: garbage, sewage, waste water, decaying matter, particulate matter, oil spill, poisonous chemicals from factories, pesticides, insecticides and fertilizer run-offs. Effects: death of aquatic plants and animals. disruption of food chains, destruction of coral reefs, health problems, destruction of ecosystems.C. Land pollution deterioration or destruction of the earths land surfaces as a result of mans activities and their misuse of land resources. Land pollutants: pesticides, insecticides, fertilizers, minerals from mining activities, garbage, chemicals from factories. Effects: health problems, destruction of animal habitat, less fertility of soil. 5. Application Draw a campaign poster showing the harmful effects of pollution. 6. Evaluation Write Yes or No in your answer sheet.1. Acid rain can help plants grow faster.2. Improper waste disposal can cause health problems.3. Too much carbon dioxide in the air can cause global warming.4. Oil spilled from leaking pipes in the oceans can cause the death of marine life.5. Biodegradable wastes in oceans and seas help sustain marine plants and animals.
