30,000 BC? – 1609: NYS Native Americans – The Science Behind the Bow & Arrow

After reviewing the results of a unit exam on the first unit  of fourth grade Social Studies,  I realized that my students have no idea what materials are used to make a bow and arrow, what its purpose was and how it impacted the lives of Native Americans.  So I created the following PowerPoint presentation, converted it to pdf and then imported it into Youblisher.com.  The resulting widget has turn-able pages!
