Come see what Newton can invent — and see how you can help! The NewtonSTEM community is invited to Newton North HS at 5PM on March 28 for the InvenTeam’s presentation of its invention — a Pedestrian Alert System to save lives in Ethiopia. The team is one of 16 nationwide to win a grant of $10,000 for experimenting and prototyping for its invention. The team now seeks local sponsors to help fund actual fabrication. (You can donate online to help the team meet its goal.) The event will be held in Room 121 (Design & Visual Communications Technology Lab) of Newton North HS, 457 Walnut Street, Newtonville, MA.
