Suppose you must design an experiment to test how a paper airplane's shape affects the distance it will fly. Your plane must fly halfway across your classroom to get the best grade. The teacher reminds you to use both imagination and logical reasoning in your design.
Write a procedure for an experiment that tests how a paper airplane's shape affects the distance it will fly. Then, describe how you might use both imagination and logical reasoning to increase your chances of discovering an airplane shape that will fly at least halfway across the
classroom.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
