Essential Questions CFQ’s • What is the effects of massive deforestation in our environment? • How do your members in the community help prevent further • destruction of the environment?
Unit Questions • How do we take good care of living things in our science lesson? • How does human activities affects the cycles in an ecosystem? • How can mankind restore the balance in nature?
Content Questions • What is the importance of forest and forest ecosystem? • How does oxygen cycle help our ecosystem?
Learning Objectives • At the end of the unit, the students will be able to; • understand what is the interrelationships in the ecosystem • explain the oxygen and carbon cycle • answers’ the questions about the ecosystem • appreciate the importance of all things in the environment • work cooperate in small groups • Think critically, and use their creativity in demonstrating their learning.
Standards • Give information to the pupils using different types of questions. • Demonstrate them what is the cycle each kind of ecosystem. • Connect it to daily lives so that they can appreciate the beauty of our nature. • Allow them to interact the discussion. • Encourage rational/specific attitude to issues related to population and development. • Enhance awareness about nomadic communities.
Unit Summary • In this unit, the student understand the facts about the interrelationship in the ecosystem. An ecosystem consists of the biological community of living things together with the abiotic or non living environment. Interrelationships are complex and varied and can be based on a number of different criteria. Organisms can be related in their feeding patterns and these interrelationships diagrammed in food chains or food webs. Other interrelationships are seen by looking at competition for resources like food and shelter and cooperation. 7
This transfer of solar energy from plants to animals, and eventually to decomposers when they die, is called a food chain. When the transfer of energy from food becomes interlinked, the overlapping food chains now become a food web. All living things need food. An ecosystem has materials that plants and animals need in order to live through oxygen and carbon cycles. The importance of forests and the forest ecosystem. Deforestation affects the world’s climate and the human activities and the cycles in an ecosystem. After understanding the cycle of an ecosystem, they make a group activities. 8
Unit summary “continuation” • They collaborate/sharing ideas about the topic. Students are in closer touch with each other through peer interaction than staff are with them. For the project, each group make a presentation through powerpoint about the cycle of the interrelationships in the ecosystem. 9
