SCIENCE VI Date: ____________ I. Objective: Describe the structure and functions of the circulatory system Values: Appreciation of the works of the circulatory system.

II. Subject Matter: Functions of the Circulatory System A. Science Concepts/Ideas: Specific functions of the circulatory system are: Carry oxygen and digested food to all cells of the body Carry carbon dioxide, water and other wastes to the respective excretory organs Permits white blood cells and anti-bodies to travel to places where they are needed to fight off foreign bodies/ invaders Helps regulate and maintains body temperature The organs of the circulatory system are: heart, blood, blood vessels, lymphatic system. B. Processes: Observing, inferring, communicating C. Materials: Chart of the circulatory system; Cut-out pictures References: Teacher's Module Science & Health 6 by Jessie A. Villegas III. Procedure: A. Preparatory Activity: 1. Review: Describe what a body system is. B. Developmental Activities: 1. Present the digestive system What are the parts? Give the function of each part. 2. Presentation Activity: Divide the class into three groups. Provide each group with cut parts of the circulatory system and strip of papers with written function of each part of the system. Let the pupils do these: 1. Examine the drawing/pictures. 2. Put them together to form a body system. a. What body system was formed? b. What organs are found in the body system that you formed?

3. Read the statements on the strips of paper and infer the function of each body organ by matching the strips with the drawing. What is the relationship of these organs to the body system? 4. Write answers on a sheet of paper. 5. Check your inferences with answers found in the module. 3. Concept Formation Class will come up with their definition or circulation. Give parts of the circulatory system Give the function of the organs of the circulatory system IV. Evaluation: Match the function with the part. 1. heart a. carry oxygenated blood to the body tissues 2. blood b. transport medium of the body 3. blood vessels c. pumping organ 4. lymphatic system d. responsible in introducing anti-bodies into the blood stream V. Assignment: What causes blood to circulate?

SCIENCE VI Date: ____________ I. Objective: Describe the structure and functions of the circulatory system Values: Appreciation of the works of the circulatory system.

II. Subject Matter: Practice desirable habits to care and protect the heart A. Science Concepts/Ideas: The Heart is the pumping organ of the circulatory system. It is about the size of a man's fist. It is located in the breastbone between the lungs with the lower and somewhat to the left. The heart is a powerful and strongest muscle in the human body called cardiac muscle. B. Processes: Observing and identifying C. Materials: Drawings of treated blood samples References: Teacher's Module Science & Health 6 by Jessie A. Villegas III. Procedure: A. Preparatory Activity: 1. Review functions of the circulatory system. B. Presentation: 1. Show an illustration of the human heart. Identify the parts. 2. Activity 1 What are the parts of the human heart? C. Concept Formation: Answer the observation part of the activity. IV. Evaluation: Identify the parts of the heart. Write the name of the part that is corresponding to each letter. A to J. V. Assignment: 1. Name the four chambers of the human heart. 2. What prevents the back flow of blood? 3. Bring film canister, rubber balloon, rubber band, plastic or rubber tube.

SCIENCE VI Date: ____________ I. Objective: Investigate the effect of exercise on the rate of heartbeat Values: Participate in worthwhile projects

II. Subject Matter: Heartbeats A. Science Concepts/Ideas: The pumping action of the heart is known as the heartbeat. Heartbeat is due to the rhythmic contraction and relaxation of the cardiac muscles. The heart beats at an average of 70 times per minute. Heartbeat between 50 and 90 are within normal range. The stethoscope is the doctor's instrument for listening to heartbeats. B. Processes: Observing, communicating, inferring C. Materials: Stethoscope, watch References: Teacher's Module, p. 2 Science & Health 6 by Jessie A. Villegas III. Procedure: A. Preparatory Activity: 1. Review parts of the heart.

B. Presentation:1. Show a red stethoscope. Where do you see this instrument? What is the use of the stethoscope? What is a heartbeat? 2. Illustrate how the heartbeat can be felt on the arteries of the temples, wrists or ankles. 3. Activity: How does exercise affect the rate of heartbeat? C. Concept Formation: 1. What is the number of heartbeats per minute while sitting down? 2. What is your heartbeat per minute after an exercise? IV. Evaluation: Give measures to the observations and inferences of the activity. V. Assignment: Count the number of heartbeats per minute of: a. your mother b. younger brother or sister

SCIENCE VI Date: ____________ I. Objective: Name and describe the different blood vessels Values: Maintaining physical fitness through health. Habits

II. Subject Matter: Blood Vessels A. Science Concepts/Ideas: Arteries and arterioles carry the blood from the heart to the body tissues. Veins and venules carry the blood from the cells back to the heart. Capillaries are the fine microscopic tubes that connect veins and arteries. B. Processes: Observing, identifying, describing C. Materials: Picture with a network of arteries, veins and capillaries References: Teacher's Module, p. 6 Science & Health 6 by Jessie A. Villegas III. Procedure: A. Preparatory Activity: 1. Check assignment 2. Review activity: How does exercise affect the rate of heartbeats?

B. Presentation:Show an illustration of the network of arteries; veins and capillaries. Let the pupils identify and differentiate the blood vessels. C. Concept Formation: Teacher explains through the illustration, the description and function of each blood vessel. Reading of the module for verification, page 6. D. Application Activity No. 3 Blood Vessels What is your SCIQ?

E. Enrichment Discuss guidelines on preparing posters. Example: Rhyme, message and number of words

IV. Evaluation: By groups, make posters on how to take care of the blood vessels. V. Assignment: Fill in the Blanks. The circulatory system is made up of the heart and a network of ______ that distribute ______ to the body in the form of blood containing dissolved ______, ______carbon dioxide, and ______.

SCIENCE VI Date: ____________ I. Objective: Identify and name parts of the blood Values: Appreciation of the importance of blood as transport medium of the body.

II. Subject Matter: The Human Blood A. Science Concepts/Ideas: Blood, the red fluid that flows through the blood vessels, is the transport medium of the body. Blood consists of the following: plasma, red blood corpuscles, white corpuscles and platelets. B. Processes: Observing, identifying, describing C. Materials: Microscope, drop of blood on a glass slide, drawing of the parts of the blood References: Teacher's Module Science & Health 6, p. 2 by Jessie A. Villegas III. Procedure: A. Preparatory Activity: The use and important parts of a microscope.
