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

related to blood pressure

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.
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.
It flows to lungs
for purification.
It is a sphygmomanometer.
Students consolidate
by group discussion.
