5. PARTS OF THE BODY

Subject: Biology Grade: 5 grade students Lesson title: human respiratory system Time: 2 hours

Targeted competencies: Knowledge:

Students learn about the importance of lungs; They also learn about the main functions of human respiratory system

Abilities:

Students learn about human respiratory system; Students learn to follow the instructions to complete a project Attitudes: Experiments will improve their thinking and knowledge

Ressources: one plastic bottle, two sticks and three balloons

Methodical guidelines:

At first, students take one plastic bottle, two sticks and three balloons. They put two ballons on the sticks that symbolize human‘s lungs and one balloon at the bottom of the bottle that works like diaphragm. When students pull the third balloon down other two ones expand as the human‘s lungs when they breath some air. This model shows how human respiratory system works.
