http://engenhariaaeronautica.com.br/author/raphael/ Thank you so much to Nancy Dufinetz for giving me this opportunity. I had a great time speaking with all of the NEMS 6th graders and their teachers. I look forward to a return visit in the future. It was also so exciting to see Melissa Chandler and the Seas Apart Book Club students. Thank you so much. All of you are amazing!
