A couple weeks ago we conducted a one week camp for middle schoolers at our engineering department. So 15 kids, 12-14 and what do my Tas Julia and Dylan, and I do to entertain them, keep them out of trouble, be safe and have them learn something? Well of course build things and destroy them or course!. So as you can see in the photos, we did concrete cylinders, popcicle stick buildings, popcicle stick dams (for water), spaghetti bridges, and filters. And spent a whole day destroying all of it. Of course then they were required to do a short presentation before they could have pizza, but at this age, they did a decent job. If fact there were some really smart kids in the group. They did great with the concrete – competing with older kids on the mix. The buildings were interesting – triangles work well, and glue will help make your spaghetti bridge bend, but not break. Lots of glue. Ridiculous amounts of glue. But it was fun, and several of them want to be civil engineers. So get them while they are young!
