Purpose: In this experiment,
Scientific
AmeriKen will examine what has the greater influence on the height
several stacked objects can reach before it topples over. Three factors
that will be examined are total surface area, shortest side length and
average side length.
Hypothesis: It is the
hypothesis of this experiment that the deciding component of object size
is the shortest side of the object as objects will have an increased chance
of toppling over along the short side as it offers less support.
Equipment: Used in this
experiment was a Jenga® game,
pen, paper, calculator, and ruler.
Procedure: The first
step is to measure the dimensions of the Jenga®
block. Essentially the experiment is performed by stacking the blocks as
high as possible. Measuring the length and width of the base of the stack
will give surface area by which the stack stands. Measuring the height
of one block and multiplying by the number of blocks stacked will suffice
in measuring height. The Jenga®
block has different measurements for its length, width, and height so that
by rotating which side the block sits on will create varying amounts. Record
results from different surface area/height test and compare.
Results: The experiment
yielding the following
