Life Science, Week 9

The Lungs & Respiratory System

Breathe in, breathe out. Age-appropriate books are sparse on the subject of the lungs and respiratory system, so we relied on a couple of fun and easy hands-on activities to illustrate the concept.


Wednesday

Using a clear plastic bottle filled with water, a straw and modeling clay, we created a model of a lung. The plastic bottle served as the lung, the water as air, and the straw as a bronchial tube. When Tessa squeezed the "lung," the "air" was forced out through the "bronchial tube" to mimic exhalation. Releasing the lung created the reverse effect...inhalation.

Thursday

Using a clear plastic bottle cut to size, balloon, piece of plastic (cut from a bag) and tape, we created a model of a lung. Tessa pushed and pulled a tab taped to the bottom of the "diaphragm" to deflate and inflate the balloon "lung."
