In this session, we will be discussing the respiratory system while creating a 3-D model of the body system. We will be discussing topics within this broad one, in specific to how breathing, or respiration, occurs. This includes the important role that the diaphragm muscle plays in respiration, the specific structures that the respiratory system consists of, and more! Our recommended age group for this project is 4 to 10 years old, although all ages are welcome!
Materials Needed:
- Plastic Water Bottle
- 3 balloons - One straw - Tape - Scissors or an Exacto knife(with recommended parental supervision) - Optional: Paper, Coloring Materials. How To
Step 1: Cut the bottom of your plastic bottle off(you can also cut it in half).
Step 2: Discard the bottle cap. Step 3: Cut your straw in half and inset them through the top end of your bottle. Step 4: Tape the ends of the straws that are located inside the bottle to two balloons, which willl act as your lungs. Step 5: Cut the top off the 3rd balloon. Step 6: Close the large end of the bottle by stretching the 3rd balloon over the opening. Optional Step: Decorate your diagram if you would like. An idea is to create a paper cut-out of a human body around the bottle, like we have done(shown in the picture below)! Step 7: Push your diaphragm in and out to see your lungs inflate and deflate, demonstrating breathing! The Lesson
This interactive model shows how the lungs and the respiratory system works, as pushing the balloon in and out of this craft inflates and deflates it with air, similar to how we breath! With the creation of their own 3-D diagram, the children will be able to make connections between their hands-on activity and their own body systems in the works. Their creativity combined with the body resemblance of the craft will allow for better understanding of the concepts at hand and the information discussed will be more profoundly retained!
