Detailed Lesson Plan in Science 4 (Parts of a seed)

DETAILED LESSON PLAN IN SCIENCE 41. LESSON OBJECTIVES At the end of the period, the pupils will be able to: a. Identify the parts of a seed b. Define GERMINATION c. Illustrate understanding on the functions of each part. 2. SUBJECT MATTER TOPIC: PARTS OF A SEED IN ITS GERMINATION REFERENCE: Science for Daily Use 4 Textbook, pp. 83-84 Materials: Charts, Pictures, Overhead Projector, Multimedia Value Focus: Cooperation 3. LESSON PROPER TEACHER’S ACTIVITY A. PREPARATORY ACTIVITIES  Opening Prayer  Checking of Attendance  Review of the Past Lesson PUPIL’S ACTIVITY B. MOTIVATION (The teacher will ask some questions) (The teacher post a picture of a seed) “Have you seen a seed?” “Yes, ma’am!” “What kind of seeds do you know?” (Pupils will respond) (The teacher will call one by one) GOD BLESS! Page 1 “What do you notice about those seeds?” “They differ in size and shape.” ACTIVITY “Now, I have here a short story and I want you to listen carefully and we will answer few questions later.” (The teacher will present “The Tiny Seed” by Eric Carle) “Did you enjoy the story?” “Yes, ma’am!” “Are you ready to answer some questions?” (Pupils will respond) Discussion Questions:  Who is the main character in the story? “The Tiny Seed”  What blows the seeds? “Air!”  Did the tiny seed fell on the ground during autumn? “No, ma’am”  Why do you think the Tiny Seed was the last one who grew? (Pupils will respond) ANALYSIS (The teacher will ask few more questions)  What approach would you use GOD BLESS! Page 2 to help the tiny seed grow?  What do you think is the purpose of the flower losing its seeds? ABSTRACTION “Seeds have been an important development in the reproduction and spread of flowering plants, Seeds, though too small, they have their own parts, like an ordinary living thing.” “Today, we are going to learn the different parts of 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 the process by which plants, emerge from seed and begin growth.” “Okay, thank you.” “I have here an illustration of a seed during germination.” (The teacher will post the illustration on the board) (The teacher will the illustration) “These are the parts of a SEED during germination.” PARTS OF A SEED  GOD BLESS! EMBRYO – a very young plant from Page 3 which a new plant grow under proper conditions  RADICLE – in a dicot is the embryonic root. “Can you point out where is the radicle in the illustration?” (A pupil will go in front and point “Within the seed, there is usually a store of nutrients for the seeding that will grow from the EMBRYO. The seed has its own food supply – called the EPICOTYL and COTYLEDONS.” out Radicle in the illustration.)  SEED COAT – develops from tissue, originally surrounding the OVULE. The seed coat helps protect the embryo. “So, where’s the seed coat in the illustration?” (A pupil will respond) “Okay, thank you. So you see, the SEED COAT is the outer part of a seed.” “Any other question?” “None, ma’am!” “Did you understand the lesson?” “Yes, ma’am!” “Again, what is a very young plant from which a new plant grow under proper conditions?” “AN EMBRYO” “What about the embryonic root in a dicot seed?” “RADICLE!” GOD BLESS! Page 4 “What do you call the seeds own food supply?” “EPICOTYL AND COTYLEDON” “Very good!” APPLICATION Group Activity Group 1: Identify the parts of the seed from the figure. Group 2: Answer the questions on the board. 4. EVALUATION (The teacher will post a chart with questions on the board) DIRECTION: On your answer sheet, answer the following: 1. It protects the embryo. a. roots b. leaf c. seed coat 2. It grows into a young plant. a. seed coat b. endosperm c. embryo 3. It provides food to the young plant. a. seed coat b. embryo c. endosperm 4. Which of these is not a part of a seed? GOD BLESS! Page 5 a. flower b. embryo c. seed coat 5. The epicotyl is a part of embryo that grows into ______. a. leaves b. roots c. stem. (The pupils will answer the short quiz) 5. HOMEWORK “Answer the following questions in your notebook.” 1. List down the factors that affects seed germination and growth. 2. Where does a flowering plant start? 3. What is a primary root? 4. What are the seeds that germinate even without soil? 5. How does a seed grow into a plant? PREPARED BY: FATIMA B. VILLAFLOR BEED 3-1 POLYTECHNIC UNVERSITY OF THE PHILIPIINES RAGAY CAMPUS GOD BLESS! Page 6
