Spaghetti Bridge Lab INVESTIGATION QUESTION: What is the relationship between the number of spaghetti noodles and the number of washers the “bridge” holds? LAB PROCEDURE: We first moved two tables or stacks of books so that they were 15 cm apart. We put one spaghetti noodle between the two tables with a cup hanging on the middle of the noodle. We added washers to the cup until the spaghetti noodle broke. Then we recorded the number of washers that the one noddle held. Next we put two spaghetti noodles in between the tables and repeated the process of adding washers until it fell or broke, and recorded the total number of washers held by the noodles. We continued the experiment with more and more noodles. PHASE 1: Design
