Teaching manual Name of the teacher: Rincy Babu std:IX Name of the school : St.michael’s H.S Thathampally Name of the subject : Biology Name of the unit : circulatory pathway Name of the lesson : components of the blood CURRICULAR STATEMENT Develop different dimensions of knowledge process skill and attitude towards the different components in the blood through lecture method ,demonstration ,power point slide presentation , group discussion and evaluation by questioning and giving assignment. CONTENT ANALYSIS Terms : Blood ,organic compound, inorganic compound, plasma, white blood cell, red blood cell, platelet. Facts : 1.Blood is a fluid tissue with a complex structure. 2.The body of an adult human beings contains about 5 liter of blood. 3.Blood flows continuously throughout the body. 4.Blood transport materials into various part of the body. 5.Blood maintenance the temperature of the body. 6.The structure of blood is suited for its function. 7.Blood consists of 55% liquid plasma and 45% blood cells. 8. Blood have plasma , water, red blood cells and white blood cells. Concept Major concept: The structure of the blood is suited for performing its function. Minor concept :1.Blood consists of 55% liquid plasma and 45% of blood cells. 2. Transport of materials , providing immunity and maintenance of body temperature are the function of blood. LEARNING OUTCOMES Enables the pupil to develop, I. factual knowledge about the component of the blood through, a. recalling the terms like organic compound, inorganic compound, plasma, white blood cell, red blood cell, platelets. b. recognizing the different components of the blood. c. Explaining about the function of blood. II. conceptual knowledge about the different components of the blood through. a. recalling the components of the blood. b. recognizing the concentration of blood cells and plasma in blood. c. Explaining the characteristics and function of blood. III. Procedural knowledge on the components of the blood through, a. components of the blood in terms of its adaptation. b. executing the practical work of separating the components of blood. IV. metacognitive knowledge on the components of the blood through, a. recognizing the components of the blood through filling the flow chart. V. scientific attitude towards the different components and function of the blood. VI. different process skill like, a. observing the chart containing the concentration of different components of the blood. b. communicating through presenting the group work. PREREQUISITE Blood is a fluid tissue which exchange gases in the cell. TEACHING LEARNING RESOURCES Chart showing different components of blood. Activity chart containing uncompleted flowchart of blood components. Power point slide depicting the characteristics and function of the blood. REFERENCE Science textbook of std IX by SCERT, Kerala. Teacher’s handbook of std IX by SCERT, Kerala. CLASSROOM INTERACTION PROCEDURE ACTUAL PUPIL RESPONSES INTRODUCTION Before entering the topic teacher asks the student to all you take breath .And ask the student how these oxygen reaches each cell of body? How does the nutrients transport all over the body? Then teacher say blood is a tissue fluid. Do you know what are the components in the blood? Today we study about the components of the blood. PRESENTATION ACTIVITY-1 Teacher says we already learn blood is a tissue fluid. Blood contain different type of cell, how does it separate?By the centrifugation blood components can separate. Then teacher explain the procedure of separation of blood component and slow virtual experiment video. Then teacher show the chart containing different components of the blood and asks the student to read it loudly. Then teacher explain the these components. ACTIVITY-2 The teacher provide activity chart containing uncompleted flow chart of blood component. Then teacher asks the student to observe carefully and also asks the students to complete this flow chart . Later teacher asks each student to read the answer to uncompleted part. Then again teacher explain about the components of the blood . ACTIVITY-3 Teacher shows the power point slid showing the characteristics and function of blood. Then teacher were call a student and asks him to read it loudly. Later teacher explain the each characteristics of blood. REVIEW QUESTION 1.What do you meant by blood? 2. How much amount of blood in the adult human body? 3. Blood contain 55% of -------- 4.What are the different components of blood cell? 5. What are the components of plasma? 6.What are the function of blood? FOLLOW UP ACTIVITY Write down the components and characteristics of blood in your science diary. Oxygen are transported through the blood. Plasma, white blood cell and red blood cell are the components of blood. Plasma, organic compound, inorganic compound, water, WBC, platelets are the components of blood. Students consolidate about the different component of the blood. FOLLOW UP ACTIVITY Write down the components and characteristics of blood in your science diary.
