Understand Developmental Periods

Research and provide an outside source on a hobby of yours (sewing, swimming, running, sports, woodworking, coin collecting, etc.). Yes, seriously! 

Provide a paragraph telling me about your hobby and why you enjoy it or how it became your hobby. Use information from your resource to provide an in-text citation. Be sure also to include a full reference at the bottom. (What is child development and why is it so important to understand developmental periods to best serve your students?) 150 words please
