Oldy But Goody

For an easy lesson on engineering and geometry the old marshmallow and toothpick towers are always fun.   We did one for cubs and used this lesson plan (PDF)with visual aids (PDF) to help us.  (This was soooo much fun to bring home intact.  We had another one, but it didn't do as well and ended up eaten. Hmmm. )
