The document describes a science investigatory project that tests how the size of a solute affects how fast it dissolves in a solvent. The experiment uses salt dissolved in water, with one sample using crushed salt and the other uncrushed salt granules. Observations showed the crushed salt dissolved faster in the water. The conclusion is that the smaller particle size of the crushed salt causes it to dissolve faster than the granules of uncrushed salt when stirred in the same amount of water.
