Dear Lord, Help us to be good, help us to do the things we should. Bless my teacher, my classmates and all. Amen Good morning Teacher! Good morning classmates Checking of Attendance (The teacher will check the attendance according to row which is in the seat plan) B. REVIEW Class can you still remember our lesson yesterday? Yes Teacher. Now, to test if you really remember. I have something to show you. I have here pictures I want you to identify what is this and its stages. Yes Teacher. Do you understand? (The teacher shows a picture of the life cycle of a butterfly) (The teacher will ask each stages of the life cycle.) “So what life cycle is that?” “Life cycle of a butterfly ma’am” “Very Good!” C. MAIN LESSON 1. MOTIVATION “Okay class, Have you seen a seed?” Yes Teacher! “What kind of seeds do you know? Can you give me examples?” (The teacher will call one by one to give examples) (The teacher will post a picture of a seed) (Pupils will respond) (Pupils will respond) “Here are some examples of seeds.” “What do you notice about those seeds?” “Yes. Very Good!” ACTIVITY Yes, teacher! “Now, I have here a short story and I want you to listen carefully and you will answer few questions later.” (The teacher will present “The Tiny Seed” by Eric Carle via video presentation) “Yes, ma’am” “Did you enjoy the story?” “The Tiny Seed” “Are you ready to answer some questions?” Discussion Questions: -Who is the main character in the story? “Air!” “No, ma’am” (Pupils will respond) -What blows the seeds? “About SEED ma’am” -Did they fell on the ground during autumn? -Why do you think Tiny seed is the last one who grew? “Do you have any idea what our lesson will be?” “Yes! Very good.” “Today, we are going to learn the different parts of a SEED.” “Here’s a drawing of a seed. You are going to identify what are its parts as we discuss our lesson.” PARTS OF A SEED EMBRYO/RADICLE – is a part of a seed that grows into a new plant. Hypocotyl – its lower end, forms the first root of the seedling. Epicotyl – its upper end, becomes the first stem. (Selected pupils will go infront and label out the Hypocotyl and the Epicotyl in the illustration) “Anyone can put a label on where the Hypocotyl is?” “How about the Epicotyl?” Cotyledons – serve for the digestion and storage of food. “Anyone who can put label on cotyledons?” ENDOSPERM – is the food-storage tissue which is digested and absorbed by the cotyledons. (Pupils will raise their hands and the selected one will go infront) “Don’t be confused between cotyledons and endosperm. Cotyledons serve for digestion while Endosperm is the food-storage which is digested and absorbed by the Cotyledons.” “Do you understand?” “Another part of the seed is the seed coat.” “Can anyone please read what seed coat is and put a label on it in the illustration?” SEED COAT – it helps protect the embryo. “Okay. Thank you. So you see, the SEED COAT is the outer part of a seed.” “GERMINATION is a process by which a plant grows from a seed.” “A seed only develops its parts only when it undergoes a process called SEED GERMINATION.” (The teacher will post the definition of GERMINATION) (She will let the pupils read it loud) “GERMINATION is a process by which a plant grows from a seed.” “There are several factors that influence germination. First is the seed it should be carefully chosen to make sure it is germinating. Then the soil and temperature must be favorable.” “I have here short video clip for you to see how a seed develops into a plant. A mung bean in particular. I want you to observe very carefully how a seed turns into a plant.” (The teacher will play the video and do the discussion while the video is playing” “Before germination the seed begins to absorb water. Without water seed cannot germinate. Then the embryo begins to grow.” “The radicle or embryonic roots come out first. As you can see the HYPOCOTYL begins to grow. The hypocotyl grows longer, it begins to straighten out. The growing hypocotyl pulls the COTYLEDONS and EPICOTYL out of the soil. (Pupils will raise their hands) Eventually epicotyls develop into the shoot and the leaves of a seedling.” “So that’s it. With proper nutrients you will be able to grow your plant well.” VALUE “Yes, ma’am” “Who among you had bald hair during their infancy? Or when you were still a baby?” “None, ma’am” “Okay there are few. But try to imagine seeds are just like a baby with no hair. As time goes by it develops and when it is properly nourished it will grow beautiful. Just like the seed when you take good care of it, it will grow into a beautiful plant.” “Did you understand the lesson?” “Are there any questions?” IV. EVALUATION Instructions: Group Activity I have here examples of seeds in its germination in each jar. Identify which part of the seed has already formed in it. Arrange it according to the stages. Write your answers on a sheet of paper. Choose one representative to discuss what stage of the seed is in the jar. Each stage should have one representative. V. ASSIGNMENT “Answer the following in your notebook.” 1. List down the factors that affect seed germination and growth. 2. Where a flowering does plants start? 3. How does the seed grow into a plant?
