Innovative Work: Respiratory System

TOPIC: HUMAN RESPIRATORY SYSTEM

AIM

The primary aim of this innovative work was to prepare a working model of the human respiratory system as a novel and creative teaching aid for the effective transaction of the content “Human Respiratory System” from the unit “Respiration and Excretion” for standard 9th students.

OBJECTIVES

1. To develop a novel and creative teaching aid for the effective and meaningful transaction of the content “Human Respiratory System.”

2. To prepare a working model of the human respiratory system as an innovative teaching tool.

3. To facilitate an engaging and interactive learning environment that fosters a deeper understanding of the breathing mechanism.

4. To develop a positive attitude among students toward the topic by using a creative teaching strategy.

PREPARATION

The working model was designed using simple materials such as a balloon, chart paper, plastic straw, cellotape, color papers, and markers. The following steps were undertaken to create the model:

  • Cut a piece of chart paper to create a sturdy base for the model.
  • Decorate the chart paper with color paper to make it visually appealing.
  • Take two balloons to represent the lungs.
  • Attach each balloon to a plastic straw using cello tape, ensuring the connection is airtight.
  • Fix the two straws with the attached balloons onto the chart paper base using cello tape. Ensure the balloons are positioned in such a way that they represent the lungs' placement.
  • Extend the two straws upwards and join them to form a single straw, simulating the trachea. Secure the connection with cello tape.
  • Blow gently through the straw to inflate the balloons, demonstrating inhalation.
  • Release the air to show exhalation.
  • Use markers to label parts of the respiratory system, such as the lungs, trachea, and bronchi.

  1. Analysis Subject: Biology Unit: Life Mysteries in Little Chambers Topic: Cell Structure Class: VIII 2. Design i) Objectives: To identify different parts of a cell To describe the structure and function of each organelles in a cell To differentiate between- Eukaryotic and Prokaryotic Cell and Plant and Animal cell ii) Summary: Cells are the basic structural and functional units of all living organisms. They come in different shapes and sizes, but their fundamental structure remains the same. Each cell is enclosed by a cell membrane, which controls the entry and exit of substances, maintaining a stable internal environment. Inside the cell, the cytoplasm holds various organelles that perform essential functions. The nucleus, often called the control center, contains genetic material (DNA) and regulates cell activities like growth, reproduction, and protein synthesis. Several organelles work together to keep the cell functioning efficiently. Mitochondria, known as the powerhouse ...
