When Science Sparkles
Floor Location : J 155 F
My hypothesis stated that Crystal growth would be greater at the high temperature of the hot plate and crystal growth would be less at the lower temperature of the fridge. The resulting average data from my experiment is:
I had based my hypothesis on the rapid movement of the molecules and the chance of the molecules meeting up and forming a protocrystal. The data shows my hypothesis incorrect.
My hypothesis is incorrect. The hot plate grew the least amount of crystals because heat of the hot plate kept the solution warm which kept the borax dissolved. The borax could not fall out of solution and start crystallizing. Crystallization is when a chemical is dissolved into a solution and then cooled. As the solution cools, a chemical comes out of solution, crystallizes, and can then be extracted from the rest of the liquid. I also had many outliers or odd results that did not fit the other results growth. Perhaps this could be due to contamination.Contamination can be due to dust on the materials or contamination such as dust may have interfered with the crystallization process and inhibited or slowed the process.
Outliers can also be due to
water trapped in the pipe cleaner may affect the weight
small variations in the borax amount that may have occurred during the pouring process or the measuring process. For example, the tablespoon could have been filled to the brim, over the brim or below the brim.
