What do feathers have to do with flying? How is a feather like a hair? Do all feathers look the same or serve the same purpose? What does a feather look like inside? These are the type of open-ended questions to explore with your students as they handle feathers, wool, and hair. In addition, children can classify birds by many characteristics, including color, shape, size, and adaptation, such as webbed feet. Classifying objects such as feathers supports children’s learning about the objects as well as how scientists order the information they gather and is part of the National Science Education Content Standards A: Science as Inquiry and C: Life Science.
