First Grading Period
I. Objective
A.  Discuss how the skeletal  protects  the internal  organs
B.  Demonstrate how the skeletal protects the internal organs
C.  Give the importance of doing regular exercise and eating calcium-rich food.

Value Integration:  Importance of doing regular exercise and eating calcium-rich food.
 
 



II. Subject-Matter
            Discussing How the Skeletal  Protects  the Internal  Organs
           
A. Science Concept: The function of some bones is to protect the delicate internal organs from injury. The skull protects the brain. The ribs protect the heart and lungs. The spinal column protects the spinal cord. The pelvic bones. guard the kidneys and other organs in the abdomen.
B. Science Processes: Observing,  Communicating, Inferring
C. References: Science Spectrum 4, pp. 11-12, Rebecca R. Fallaria, Nenita A. Apolinario, Jesse D. Ronquillo, Into the Future: Science and Health 4, pp 10-11, PELC #1.3, p.1
D. Materials: Enlarged picture of the different kinds of bones and some internal organs
E. Strategy Used:   4 A’s Strategy

III. Procedures:
            A. Activities:
1.  Let the pupils match the enlarged pictures of  some bones and internal organs.
2. a.    Divide the class into three. Let them perform activity 1.7 of pages 10-11 of Into the Future: Science and Health 4.

            Activity 1 – For Protection
 for group 1: You need: uncooked egg, transparent plastic container
            Procedures: 1. Put an uncooked egg inside a transparent plastic container. Cover it.      
                                 2. Slap the wall of the closed container with your palm.
for group 2: You need: Piece of cake, uncooked egg, small cage, small rubber ball
                        Procedures: 1. Put a piece of cake and an uncooked egg inside a small cage.
                                             2. Hit the cage with a small rubber ball several times.
for group 3: You need: ballpen with transparent body
                        Procedure: Let them observe it.                 
      b. Let each group reporter to do the reporting.


           
            B. Analysis:
                        1. (Matching bones and internal organs)
                            a. What internal organs were protected by skull, vertebrae, ribcage and pelvic girdle?
                            b. Why do the internal organs need protection from bones?
                        2.  (Group Activity)
                            a. 1. What happens to the egg inside the container?
                                 2. Why do you think it was not cracked or damaged?
                            b. 1. Why do the cake and egg inside the cage were not damaged?
                                 2. What gives it a protection?
                            c. 1. What is found inside the narrow tube?
                                 2. If the tube represents the backbone, what delicate body part is found in it?
                                 3. Which bones in the body serve a similar purpose as that of the plastic container?
                                 4. What is the function of these bones?
                                 5. What would happen if some vital parts of the human body were not protected by bones?
            C. Abstraction:
The function of some bones is to protect the delicate internal organs from injury. The skull protects the brain. The ribs protect the heart and lungs. The spinal column protects the spinal cord. The pelvic bones. guard the kidneys and other organs in the abdomen.

 
1. Input: Discussion on how the skeletal  protects  the internal  organs.





-         Why do we need to protect the internal organs?
-         What will happen if we will not take good care of our bones?
Value Integration:  What would be the best thing to do in order to have tough and strong bones to protect the human body?
            2. Generalization:  How do the skeletal  protects  the internal  organs?
IV.           D. Application: (using rubric scoring guide-essay)
                 a. State the major function of the bones.
                 b. Discuss this quote briefly, “The strong should support the weak.”
V.             E. Enrichment Activities
                   List the kind of joints and their movement.
