Procedure A Preparation  Greeting  Prayer  Checking of attendance  Pick – up the pieces of the paper  Checking of prior knowledge B Motivation The class will play the game “lap sit”. All of the members of the class will stand in a circle side by side (close enough so that the shoulders can touch). Tell them to turn 90 degrees to their right and put both of their hands on the shoulders of the person in front of them. Then on the count of three, they will sit down slowly on the knees of the person at the back of them. They should be able to form a continuous circle and hold the position for 30 seconds or so. After, have everyone stand up at the same time.

Note: This might be an uncomfortable task for anyone who doesn’t feel to be too close to anybody and a risk when mixing tall people with small people. A person who chooses not to participate could be a watcher to see if the class is lined up properly. C Motive Question The teacher will ask the students to connect the lap sit game to the fact that “everything has an important role to play in the web of life”. D Lesson Proper / Presentation D.1. Pre – reading  Overview The teacher will show a picture of an ecosystem in which the biotic and abiotic factors are present. The students will identify which is which.  Vocabulary preview and development The students will be asked to define the terms written on the board. Then write as many words as they can which can be associated with the given terms. 1. biotic 2. abiotic 3. producers 4. consumers 5. climate D.2. During reading  Silent reading activity The teacher will give hand-outs to the students then the students will read it silently.  Immediate oral feedback The teacher will raise questions about the text material and the students will be encouraged to respond and share their thoughts. D.3. Post reading  For comprehension response, the teacher will require the students to reflect and write an essay, minimum of 500 words about the importance of the biotic and abiotic components for a balanced ecosystem.

G Assignment Every life form has a place under the sun because even unknown to man, every living thing is important to someone or to something. And even those that have no life are part of the pattern. For your assignment, your task is to create a model of an ecosystem with biotic and abiotic components in it. Be creative! 
