D. Concepts: a. Photosynthesis is a process whereby plants manufacture their own food by CO2 trapping light energy from the sun to convert carbon dioxide ( ) and water ( H2

O) into sugar/glucose.

b. The process of photosynthesis are as follows: Step 1: Chloroplasts in the plant cells capture the energy from sunlight. Step 2: The captured light energy is used to produces sugar and oxygen from CO2 . water and Step 3: Sugar produced are used by the plant cells for energy. Step 4: Oxygen exits through stomata on the underside of the leaf. E. 21st Century Skills: 

III Procedure A. Preliminaries Teacher’s Activity

Student’s Activity

a. Greetings: “Good morning class.”

“Good morning ma’am.”

b. Opening prayer: “Earl, please led the prayer.”

Earl: “Let us put ourselves in the presence of the Lord. In the name of the Father and of the Son and of the Holy

Spirit. Praise be thy name of our Lord Jesus Christ”. Others: “Now and forever, Amen.” All: “In the name of the Father, and of the Son and of the Holy Spirit Amen.” “Please be seated.”

c. Checking of attendance: “Beadle is there any absentees today?”

Beadle: “There are no absentees today. All are present ma’am.”

d. Checking of assignment: “Yes ma’am.”

“Leaders of the group, did you check the assignment of your group members?”

“Our topic for today is about this”

“So who can tell me what the diagram is all Kelpie: “Balancing equation ma’am about? Moreover, why do you think so? Yes, because there is a chemical equation.” Kelpie?”

“Okay thank you Kelpie. How about you Lydia?”

“Thank you also Lydia. So Lydia’s right, this diagram represents the process of photosynthesis.”

C. Lesson Proper Teacher’s Activity

Student’s Activity

“So our topic for today is all about photosynthesis” (The teacher will flash pictures.)

“Class what do you think is the Bridgette: “They are important raw materials significance of those pictures? Yes or the reactants for photosynthesis.” Bridgette?”

“Is it correct class?”

“Yes ma’am.”

“Okay, that’s correct. It is true that Ermine: “Without the presence of light energy carbon dioxide, water and light energy coming from the sun, plants cannot make their are the important factors in the process own food.” of photosynthesis. What do you think is the role of light in this process? Yes Ermine?”

“Ermine is correct. The light energy is very important in the process of photosynthesis. The captured light energy from the sun is used to produce the glucose/sugar, which is the food of the plant and the oxygen. Is it clear?

“Yes ma’am.”

“Based from the explanation that you Jade: “The reactants are the carbon dioxide, had heard a while ago. What is now the water and light energy while the products are general chemical reaction/equation of the glucose and oxygen.’ photosynthesis? Yes Jade?”

“Jade is correct. Now the general balanced equation of photosynthesis is;

6CO2+6H2O+Light C6H12O6+6O2 Are there any questions?”

energy

“Okay let’s come now to the process of photosynthesis. I have here a video presentation. While you are watching take note on how the process occurs. Okay class?”

“None ma’am.”

“Yes ma’am.”

(After the video presentation) “So what is now the first step/place that Elizabeth: “The chlorophyll which is the green takes place in the process? Yes pigment inside the chloroplast in the plant cells Elizabeth? captures the energy coming from the sun.”

“Very well said. Who else? Yes, Hatori: “The captured light energy is used to Hatori?” produce glucose from water and carbon dioxide.” “That’s correct last one. Yes, Jemarie?”

Jemarie: “The sugar/glucose produce are used by the plant cells for energy and also oxygen exits through the stomata on the underside of the leaf.”

“Yes all that you have been said are true. Basically that is how the food making of the plant happens. Are there any questions?”

“None ma’am”

“So much for that get one half sheet of paper” IV Evaluation Enumeration and Identification

1-3 the reactants in the process of photosynthesis 4-5 the products in the process of photosynthesis 6. It captures the light energy from the sun. 7. It is a process whereby plants manufacture their own food. 8. It is where oxygen exits and it is found underside of the leaf. 9-10 the general balanced chemical equation of photosynthesis V Assignment Study the next topic and answer the Enrichment Activity on a one whole sheet of paper on pp. 174.
