Comparing Density and Volume Summer Science Academy

This study aims to describe the concepts of mass and volume while estimating the relationship between them. Through measurements of experimental items, such as a cylindrical object and a rectangular cube, we calculate their masses and volumes to determine their experimental densities. A paired t-test is employed to compare the experimental densities with accepted values. The results indicate that there is no significant difference between the two, confirming the foundational formula of density: Density = Mass / Volume.

  1. Comparing Density and VolumeSummer Science Academy Friday July 22, 2005 LeMoyne-Owen College Group Four (4)

  2. Group Members • Marico Q. Frazier Hendaia Wondim • Timothy Renfroe Ashley Gaither

  3. Purpose • To describe mass and volume for each experimental item. • To estimate the relationship between mass and volume. • To compare experimental and accepted density values.

  4. Methods • Measure the mass of the right cylinder and the rectangle cube • Measure to find the radius of the cylinder and its height to find its volume • Measure to find the length, width, and height of the rectangle cube to find its volume • Divide the mass of each object by its volume to find the experimental density

  5. Working Hard Finding an Answer

  6. Measurements Volume = Length * Width * Height

  7. Descriptive StatisticsGraphical Method

  8. DensityDensity = Mass / Volume

  11. Hypothesis • Null Hypothesis: Experimental & Accepted Densities are same. • Alternative Hypothesis: Experimental & Accepted Densities are different.

  12. Paired t-test P-value > 0.05. So, failed to reject null hypothesis.

  13. Conclusion Since we failed to reject null hypothesis, the experimental density supports the accepted density. Thus, we confirm the formula, Density = Mass / Volume.
