Please enter your data in the table below.

Table 1. Group results for the separation of a mixture of sand and salt.
 * Lab Partner's Initials || Percent of Sand || Expected Percent of Salt || Measured Percent of Salt || Description of sand after separation (observed under microscope) ||
 * Vivian, Srishti || 82.6% || 17.4% ||  || Our filtered out sand, still seems to contain small amounts of sand, that looked like cubes. However, along with that, there were shiny asymmetrical crystals in the sand, too, that could possibly be also salt. Also, the sand now looks darker in color, and slightly larger. ||
 * Aman, Esther || 86.3% || 13.7% || 18.2% || After our mixture was filtered, we came to the conclusion that our sand is 99% pure, as there was an average of 1 sand particle per 5 pieces of salt crystals. When we compared the pure sand and our filtered sand, they looked very similar under the microscope. ||
 * Amelia, Miyu || 82.6% || 17.4% ||  || In the observation of the sand after separation, we concluded that not all salt particles were filtered out. We compared our sand with the sand/salt mixture in the glass, and there were no subtle differences. Both were mostly sand, but the crystals from the salt were still visible. ||
 * Nikita, Raelene || 58% || 42% ||  || Under the microscope, we compared our filtered sand with the clean sand. We noticed that the clean sand's similar to our filtered sand. However, we conclude that not every particle of salt is filtered and separated completely from the mixture. ||
 * Hae-Woong, Shawn || 63.63% || 36.37% ||  || In our filter under the microscope, there was lots of different stones, and different colors that I can't see by using eye. Also, there was some salts left, which weren't separated when we put the water in to the filter paper. ||
 * Paddy, Grace || 83.3% || 16.7% ||  || After we filtered our mixture, we observed the filtered sand with microscope. We noticed that the filtered sand is not pure because we saw some salt inside the sand. The crystals of salt were white and shinny. ||
 * Nigel,Carolin || 86.2% || 13.7% ||  || When we looked at the sand under the microscope, we still saw a small amount of salt in our sand. Compared to the pure sand ours still had little crystals in it. ||
