SURABHILA SADANANDAN

INNOVATIVE TEACHING MANUAL
Name of the teacher         : Surabhila Sadanandan                           Std    : IX
Name of the subject          : Biology                                                      Date: 18/09/2014
Name of the unit    : Circulatory Pathways                                         Duration: 45 min
Name of the lesson            : Blood pressure

CURRICULAR STATEMENT
Develops different dimensions of knowledge, process skill and attitude on blood pressure through lecture method, group discussion and evaluation by questioning.



CONTENT ANALYSIS

TERMS                 : ventricles, contraction, force, arteries, pressure, systolic pressure, diastolic pressure, heart, sphygmomanometer, lungs , body, aorta.
FACTS: 1. When the ventricles contract the blood flows with force into the arteries.
             2. The blood exerts pressure on the walls of the artery.
                              3. Systolic pressure should normally be 120 mm Hg.
                             4. During diastole blood enters the heart.
                              5. The diastolic pressure should be 80 mm Hg.
                             6. The instrument used to measure blood pressure is                             Sphygmomanometer.
CONCEPT
Major concept: A person’s blood pressure is expressed using both systolic and diastolic pressure.
Minor concept: 1.Systolic pressure is normally 120 mm Hg.
2. Diastolic pressure is normally 80 mm Hg.

LEARNING OUTCOME
Enables the pupil to develop,
1.     factual knowledge on the blood pressure of human through
a.     recalling the new terms like ventricles, arteries etc.
b.     recognizing the different pressures of human.
c.      explaining the function of arteries and veins.
2.     conceptual knowledge on the blood pressure of human through
a.     explaining thediastolic and systolic pressure.
b.     recognizing the pressure on the walls of the artery.
3.     procedural knowledge on the blood pressure of human
a.     differentiating the diastolic and systolic pressure.
b.     finding the pressure variation in human.
4.     metacognitive knowledge on the blood pressure through
a.     understanding the role of arteries and veins.
b.     recognizing the pressure exerted by blood on the walls.
5.     scientific attitude on the blood pressure
6.     different process skills like,
a.     observing the blood pressure through sphygmomanometer.
b.     communicating about the disease by variation in blood pressure.

PRE REQUISITES
            Blood pressure is the pressure exerted by blood to the walls of blood vessels when it flows through it.
TEACHING LEARNING RESOURCES
            ACTIVITY CARD
                        Activity card to write the health problems related to blood pressure
            ICT MATERIAL
                        A slide showing sphygmomanometer.
            REFERENCE BOOK
1.     Biology text book of Std.IX, SCERT
2.     Teachers Hand Book of Std.IX, SCERT








                                           
CLASS ROOM INTERACTION PROCEDURE
EXPECTED PUPIL RESPONSE
INTRODUCTION
              Have you heard about blood pressure? Then what is meant is blood pressure? Do you know the normal blood pressure of a human being? Let’s discuss on blood pressure in detail.
PRESENTATION
Activity 1
              Teacher distributed an activity card to write the health problems related to blood pressure. Then each group was asked to read out the answer.

Write the health problems related to blood pressure.






CONSOLIDATION
              In human being systolic pressure is 120 mm Hg and diastolic pressure is 80 mm Hg. Any change in these causes some health problems like fainting, dizziness etc.
Activity 2
Teacher inquires the students that where the blood doesflow after it enters the arteries? Why does it flow to the lungs?
CONSOLIDATION
It flows from right ventricles to lungs and from left ventricles through aorta to different body parts.
Activity 3
Teacher shows the students a slide of sphygmomanometer and asks them to identify the picture.
CONSOLIDATION
         Sphygmomanometer is the instrument used to measure blood pressure.
CONCLUSION
     The students were asked to discuss and consolidate the blood pressure.

Yes, we have heard.
Pressure exerted by blood on the walls of blood vessels.












·        Heart attack
·        Atherosclerosis
·        Stroke








It flows to lungs for purification.









It is a sphygmomanometer.






Students consolidate by group discussion.











REVIEW QUESTIONS
1.     What is blood pressure?
2.     What is systolic pressure?
3.     What is diastolic pressure?
4.     What is the normal blood pressure of human beings?
5.     Where does the blood flows after entering the arteries?
6.     Which instrument is used for measuring blood pressure?

FOLLOW UP ACTIVITY:  Find the health problems related to blood pressure and record it in your science?
