"Feathers row from the skin of a bird and protect the bird from rain, snow,wind and cold. Some of the feathers act as cloaks or macintoshes and others as underclothing...the children may observe how and where the different kinds of feathers grow. The pupils should also study seperately the form of a feather from the back, from the breast, from the underside of the body, and a pin-feather." HNS, pages 30-31
Since we do not have a hen available for us to study, I invited the kids to walk down to the beach to find feathers. We brought them home and worked on trying to identify where on the bird (gull) the feathers were from, and how they were used. We learned about how they are built and how they work.
