CLASSROOM INTERACRION PROCEDURE
PUPIL’S RESPONSE

INTRODUCTION

Teacher maintains a rapport with the students. Teacher tell the students, today I am going to tell a story about blood, listen carefully. 

PRESENTATION

There were three friends lived in blood happily. They were erythrocyte, leucocyte and platelet.  The nick name of erythrocyte was red blood cell and that of leucocyte was white blood cell. Both of them were very proud about their power. They ignored platelet due to its weaker appearance. One day there occurred a quarrel between erythrocyte and leucocyte related to their power. Erythrocyte argued that it can carry oxygen in its haemoglobin and it can so maintain life. Leucocyte’s argument was that it is stronger because it can fight with many deadly pathogens.   Platelet came and advised to stop quarrelling, but they didn’t listen that. After some time there began to high speed flow of blood due to a wound. All three friends began to flow towards the wound site. They tried to escape from that flow, but couldn’t. When platelet came nearer to the wound it took some equipment and tried to seal the wound. At last the platelet won in his effort and both erythrocyte and leucocyte thanked to it. From then onward they stopped quarrelling and lived in unity.  
ACTIVITY NO: 1
Teacher tells the students to find out the role of blood cells from this story
CONSOLIDATION
Erythrocyte- Carry oxygen in haemoglobin and help in gas exchange
Leucocyte- It helps to kill pathogens that enter our body thus providing immunity
Platelet- It helps blood clotting to prevent blood loss during cuts or wounds happen.
ACTIVITY NO 2
Teacher presents diagrams of blood cells in power
point and tells the students to compare the diagram and to write about it throgh discussion.


CONSOLIDATION

Erythrocyte- They are disc shaped, lack nucleus
Leucocyte- They  are nucleated. There are 5 types of leucocytes namely basophil, eosinophil, neutrophil, monocyte and lymphocyte. They possess different shaped nucleus.
Platelet_ They have no definite shape and lack nucleus








Carefully listens the story












Remember the story and write about the functions of blood cells


Listen the answers carefully




Discuss and write about the blood cells.











carefully listen to teachers explanation

 ENRICHMENT ACTIVITY

What will happen if there occur variation in numbers of these blood cells.
