Welcome to
Petaluma, California, where you will find a family owned organic egg
farm. It was the first certified organic farm in California apparently, and
you can discover just what makes it organic. Video clips are available at
many stops; you can view how eggs are loaded onto the conveyer belt and how
they reach the transport stage for grocery stores. When you've finished your
online field trip, you can experiment making naked eggs and using them for
various science experiments, with the 2nd and 3rd links above.
