Materials: Respiratory system visual aid, Glue, Scissors, Colored Construction Paper, Yarn, Beans, Macaroni Noodles, Sponges, Straws, Cotton Balls, Small Balloons, Crayons
Instructional Strategies: 1) The teacher will introduce the respiratory system and display a visual aid of their respiratory system. 2) The teacher will begin the lesson by taking a balloon and blowing it up. The teacher will ask the class if they have an idea what organ might be similar to the balloon and the way it was inflated.The students should arrive at the answer: the lungs. 3) The teacher will present information on the respiratory system. The students will take notes of the material in an outline form. The information that the teacher should include is: the organs that work together in the respiratory system are: the lungs, the nose, the trachea, the bronchi. Everybody has a set of two lungs. The lungs are similar to balloons. When we breathe in our lungs fill with air. When we breathe out, we are breathing out carbon dioxide. Our lungs work together with our heart to carry oxygen all over our body. The air first enters our body through the nose. The trachea is a tube that allows the air to go to the lungs. 4) The teacher will discuss the effects that pollution and smoking has on the lungs. 5) The students will brainstorm additional areas of the body pollution and smoking can effect. 6) The student will create a diagram of the respiratory system using above materials. The teacher may want to add small balloons to the available supplies to depict the lungs. If students create a similar construction of all the body systems and/ or individual organs, they can be used in the “Human Body” culminating activity listed after the description of the musculoskeletal system.
