Human Muscles

Lesson Plan of Introduction of Human Body (Muscles)

General Science Grade IV

Students’ Learning Outcomes

·         Identify major parts (Muscles) of human body.
·         State functions of major parts (Muscles) of the body.

Information for Teachers

·         Muscles are the parts of our body that can contract.  When muscles, attached with bones contract. They produce movements.
·         The 650 muscles in the body not only support movement — controlling walking, talking, sitting, standing, eating and other daily functions that people consciously perform — but also help to maintain posture and circulate blood and other substances throughout the body, among other functions.
·         The main framework of the body (skeleton) is covered by muscles, whose function is to permit movement and maintain posture

Material/ Resources

Charts of human Muscles, textbook

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.



·         With the help of charts and pictures ask the students to identify different muscles present in the body.
·         Inform the students that whenever we do any work e.g. blinking of eyes, eating food, drawing or writing, the muscles involved, contract and relax.


Sum up / Conclusion

·         Muscles can contract and produce movements.
·         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.
