Nancy B's Science Club MoonScope
Calling all budding astronomers! Take your star-gazing to a whole new level with this kid-friendly telescope and accompanying journal packed with facts and fun activity prompts.

You can feel your lungs moving in your chest every time you take a breath, but it might be hard to imagine what they look like and how they actually work. Imagine no longer, as the Plastic Lung Apparatus with Two Balloons provides a visual demonstration of how the lungs work.

Show how the lungs are emptied and filled with air by relaxation and contraction of the diaphragm muscle! Two balloons attached to a Y-tube simulate the lungs as the chest cavity is represented by a half-gallon plastic bell jar with an open top and stout rubber sheet which acts as a diaphragm.

As the diaphragm is pulled downward, the atmospheric pressure is lowered inside the chamber causing the lungs to expand, taking in air. When the diaphragm is released, the lungs deflate.
