Our third annual S.T.E.M."gingerbread" house program was this past weekend, and was as much fun as ever! This year, kids were offered a new design challenge: to use large marshmallows as a base for their graham cracker creation rather than the milk carton we have used in years past. Some took the challenge, some used the traditional method, but all had fun! So much good engineering happened this year! Here's our show!
