@perl Hanna hypothesizes that granite is denser than sandstone. How can Hanna test her hypothesis?
A. Melt each rock down inside a high-temperature furnace, and then measure the volume of the two liquefied rocks.

B. Weigh each rock to determine which is the heaviest, and thus the densest.

C. Measure the mass of the rocks with a balance and the volume of the rocks with water and a graduated cylinder. Then calculate their densities.

D. Examine the rocks under a hand lens and determine which rock seems to have the largest particles.

Theoretically, this belongs in the science department, but I would say that she should choose C.

i know it belongs in the science department, no one would help me

@Surana is correct. You would use the density formula, d=m/v which requires both the mass and volume.

Oh, that's nice to hear. Glad that science thing I learned two years ago that I haven't used since then helped.
