Hypothesis- Air tempe
Design - Variables
Investigating the relationship of the height, thickness, and material of a column vs
how sturdy it is.
Different heights, thicknesses, and materials of column
Levels of IV: 8 /11, 8 /5 , 4 /11, 4 /5 sheet
Evaluation & Conclusion
In conclusion, the hypothesis was correct on both counts. The closer the height was to
the diameter, and the thicker the material, the more mass the column held. The columns that
were 5.5 inches high, the height closest to the diam
