Catcher in the Rye Essay
Sarah Grassel 9/4/13 Battle of the Pennies Purpose: To see how long the noodles will stand their ground against the pennies in the epic battle of the pennies or to put into more scientific terms, to find the mathematical and graphical relationship between the number of pennies the spaghetti bridge could support could support and the number of spaghetti strands in the bridge. Procedure: Independent/Controlled variables = number of spaghetti strands, weight of cup, distance between supports, and length of spaghetti noodle. Dependent variable = number of pennies before the spaghetti bridge breaks We can control the independent variables by choosing how many strands of spaghetti will battle for that trial, manipulate the strands (soldiers) length, and we all had the same cups.
