PUPIL RESPONSE

Preparation Do everybody like proverbs ? I will ask a proverb It can flow, but it is not water, it is present in animals but not in plants. It has red in colour. Can you name it ? So, today we are discussing about the topic “Blood Cells (BB)” Presentation ACTIVITY No.1 Chart contain the diagrams of different blood cells are shown in the pupil and they were asked to draw the structure of different blood cells.                   CONCEPT FORMATION                       Different blood cells ACTIVITY No. 2 Activity cards are given to the pupil and they were grouped and asked to write about the functions of blood cells.                      CONCEPT FORMATION                        Functions of blood cells ACTIVITY No. 3 Chart indicates the components of plasma are shown in the pupil and they were asked to read the chart.                        CONCEPT FORMATION                               Blood Plasma Closure Blood consists of RBC, WBC, platelets. Blood is a fluid tissue with complex structure  blood contain 55% plasma, 45% blood cell.  Blood flows continuously throughout the body.
