Worm up Activity

·         Ask the students if they can name different parts of their bicycle. Write students’ responses on the board.
·         Tell the students that as the bicycle has many parts, our body is also made of many parts. These parts are called organs.
·         Ask the students to name all the organs of body which they can see and touch. Write students’ responses on board.
·         Make them focus that these are the external parts of their body e.g. ear, eye, teeth, and skin.
·         Explain that like these external parts there are some parts inside the body which also perform variety of functions.




·         Introduce the need of transport of materials to and from different parts of body. This learning can be achieved by making questions like the following.
    —-When we eat food, it goes to our stomach and intestine. All parts of our body need food.    
           How do they get food from intestine?
   —–When we inhale air, our lungs get oxygen from air. How all parts of our body get oxygen
          from lungs
   —-All parts of our body make carbon dioxide but only lungs are able to remove it from body.       
         How the carbon dioxide from all parts reach to the lungs?
·         Inform the students that food from intestine, oxygen from lungs and carbon dioxide from whole of the body enter in the blood
·         Make line- drawings to demonstrate the role of heart and blood vessels in pumping and carrying blood to different parts of the body.
·         Ask the students to close their fist. Tell them that the size of their heart is of their closed fist.

Sum up / Conclusion

·         The upper two chambers of the heart receive blood from blood vessels while the lower two chambers push blood to other blood vessels.
·         Draw following table on the board.
·         Instruct the students how to fill the table.
·         They will explain their understanding by completing the table
 Organ name


Follow up

·         Ask each student to choose one of the organs taught in this lesson. All students will make drawings of the chosen organs. They will also write the function of the organ.
