5-E Model for Teaching Inquiry Science
Students will create a model that demonstrates the interaction among the lungs, chest and diaphragm during breathing. They also will make predictions, investigate, record observations, and draw conclusions based on their investigations. They will learn that the diaphragm and rib muscles change the size of the chest cavity and control whether air enters or exits the lungs.
Specific science concepts addressed in this activity include the following.
- Volume changes in the chest cavity cause air to move in and out of the lungs.
- When we breathe in, oxygen moves from the air in our lungs to our blood and carbon dioxide is released from the blood to air.
Keywords: breathing | breathing rate | diaphragm | lung capacity | lung model | lungs | respiration | Elementary science investigation | lung model
