Basic Information

Drawing a parallel between the human body and a machine and discussing the similarities and differences will help the students begin their journey towards understanding nature’s most amazing ‘machine'.

Lesson plan Details

Duration: 
02 hours 00 mins
Introduction: 

Understanding the human body in its entirety can be difficult for children who are often overwhelmed by the complexity of the whole. One way to simplify it  is to compare it to a machine, with many different parts, each with a different purpose and structure. Drawing a parallel between the human body and a machine, discussing the similarities and differences will help the students begin their journey towards understanding nature’s most amazing ‘machine.’

Objective: 
  • To encourage the child to explore beyond the external concept of the human body and discover it’s functioning from within.
  • To help students list and get familiar with the different systems of the human body and understand their functions.
  • To adopt a hands-on approach in learning about the human body by involving all the faculties in comprehending the facts related to the subject.
  • To help the students list and understand the similarities and differences between the human body and a machine.  
Steps: 

Session 1: The human body – An introduction

Duration of the session: One hour

Step 1: Generating Interest: Introduce the topic and initiate a discussion.

  • What does the human body mean to us?
  • How important is it to us?
  • Why do we need to study and understand its structure and how it works?
  • Why is its care and maintenance our responsibility?

 

 

 

 

Step 2: Explanation: 

  1. Discuss the similarities and differences between the human body and a machine.
  • Both the human body and machine need fuel/food to work/function properly.
  • Both produce heat while working.
  • Both experience wear and tear and need to be maintained etc.
  • Also discuss the differences, like the human body is not completely switched off, when it rests unlike a machine etc.

 

 

 

 

  1. Ask the students to list the visible parts of the human body.
  2. Now ask them to list the internal organs and systems they know.
  3. Draw a large and clear outline of the human body on the board and use coloured chalks to mark the different systems on it. Discuss how the internal organs correspond to external body parts, e.g. nose to the respiratory system, eyes to the nervous system, mouth to the digestive system etc. 

 

 

 

 

 

 

 

 

Session 2: The different ‘machines’.

Duration of the session: One hour

The human body is a complex and finely balanced machine. Each part has its own vital role to play in the smooth running of the body. Discuss and explain the different systems in the human body.

Step 1: Generating Interest

Discuss how different body systems function like different machines.

Explain, the heart functions like a pump, drawing up the blood and pumping it out again. The lungs act like purifiers, removing unwanted carbon dioxide from the body and carrying oxygen into the blood. The eyes act like a camera. Ask your students to come up with other analogies on their own. They could try to find comparisons for the nervous system, the skeletal system, etc.

 

 

 

 

Step 2: Explanation

1. Discuss and explain why maintenance of the human body is essential and how it is achieved.

The body gets its fuel for functioning from food, water and air.  It maintains itself by exercise and recreation, and it recovers and repairs with rest. Brainstorm a list of things the students can do to keep their bodies functioning smoothly. Ask each student to write and illustrate one health or safety rule they can follow. Display the rules on a classroom bulletin board.

 

 

 

 

2. Distribute copies of the ‘Amazing facts about the human body’ (resource 1) among the students and initiate a brainstorming session. Encourage the students to share any other facts they know and add the same to the list.

Excellent lesson plan to teach the basic information along with some amazing facts related to the human body to the young students .
This will definitely make learning interesting and will be able to create more curiosity in the students.
Both the resources are also very good.
