Shoo, Fly!

We learned about the respiratory system this morning, and made a working model of our lungs.

The orange balloon represents the diaphragm. When the diaphragm contracts and moves downward (inhalation), air rushes into the "lungs" through the trachea and bronchi, filling them up. The opposite happens when the diaphragm relaxes during exhalation.

We got insect screens installed today for our ranch sliders and front door. We're very pleased with them as they'll keep the flies and mozzies out, and allow cool air in. They fold neatly into a cassette when not in use and are practically invisible. Summer here we come! 

The little lady and I were up late preparing food for our beach picnic lunch with friends tomorrow. She got up mid-sleep and naturally became my little taste-tester for sushi and chocolate chip cookies. :)
