43. Date: ____________

I.OBJECTIVE:Explain the process of photosynthesis using a diagram; enumerate the raw materials needed by green plants in order to make their own food. Identify the products of photosynthesis.

Values:Eat green and leafy vegetables that are nutritious

II.SUBJECT MATTER:Photosynthesis A.Science Concepts/Ideas: Photosynthesis is the process of manufacturing food in green plants. It involves the synthesis of carbon dioxide and water in the presence of sunlight. The raw materials needed in food making process are chlorophyll, carbon dioxide, and water in dissolved minerals from the soil. The end product of photosynthesis is a form of sugar. The by-product of photosynthesis is oxygen. Green plants can manufacture their own food because of chlorophyll.

B.Processes:Defining, describing

C.Materials:Charts, posters, diagram showing how photosynthesis takes place, flannel board

III.PROCEDURE:A.Preparatory Activity:Checking of Assignment Review:1. How do animals get their food? 2. How do plants get their food?

B.Developmental Activities:1.MotivationCan you name some green plants found in the community? Identify the substance that gives the green color to these plants.

2.Presentation/Activitya. Present the words sunlight, carbon dioxide and water on the board. b. Tell that sunlight is the source of energy. c. Tell that plants get energy from the sun. This pigment traps solar energy. 3.ApplicationDraw and study the diagram and explain the process of photosynthesis. 1. What is the source of energy in photosynthesis? 2. What traps sunlight or light energy? 3. What happens to chlorophyll when energy from the sun is trapped? 4. What raw materials are combine to form glucose?

Study the different chemical reactions involved in the phase;
