The Needham Public Schools’ Science Center offers after-school enrichment classes at Newman Elementary School (1155 Central Avenue in Needham).  This fall, it offers Eco-Adventures (Wednesdays starting September 29, 3:30-5PM) for kids ages 7-11 who like exploring nature outdoors and don’t mind “creepy crawlies” and a little dirt.  The program includes scientific observations, games, and crafts focused on environmental issues.  $200 for 8 weeks.   Register online.  For more information, call 781-455-0475 or e-mail sciencecenter@needham.k12.ma.us.
