Students learn about the process of engineering the fun way—by heading to Revere Beach On a recent Monday afternoon,four Tufts students were kneeling in the hot sand on Revere Beach, mixing sand and water in a bucket, and then packing the mixture into a enormous,hollow LEGO brick. They were trying to fabricate (to make up, invent) the building blocks for small structures to surround a large, two-foot-tall sand castle.
The first mixture was so damp and tightly packed that it wouldn’t near out of the mold. The second batch came out, or but immediately fell apart—too dry. The third ratio produced a perfect mold and a chorus of “Wow!”
