Today we did an experiment called magic sand. The purpose of the experiment was to learn more about compounds and their physical properties. We learned that 2 most come compounds are ionic and covalent. An ionic compound is a chemical compound in which the ions are held together. In a covalent compound the atoms bond together by sharing electrons. We also learned the differences between Hydrophilic and Hydrophobic. Hydrophilic means that the molecules have a tendency to mix with, dissolve in water, or to get wetted by water. While on the other hand Hydrophobic is the observed tendency of nonpolar substances to aggregate in aqueous solution and to exclude water molecules.
In order to conduct the experiment we needed: Glass Tray, Reptile Sand, Glass Stir Rod, Water, a Glove, and Silicone Spray. We first started off by getting the glass tray and we then filled it with the reptile sand. From there we went through a six phase process where we coated and mixed the sand with the Silicone Spray. With the glove and and stir rod we mixed it together and made sure it was applied thoroughly. We then added water to complete the experiment. Surprisingly the sand resisted the water and it seemed as if the water was floating on top of the sand. Since sand is hydrophilic is mixes and dissolves with water, it was interesting to see it turn to a Hydrophobic substance. When Mixed with water weird to see it resist the water and make it seem as if the water was floating.
Looking Back:
Overall the experiment turned out as planned and nothing bad happened. It looked great overall it did it’s job and there was no mess.
Looking Beyond:
In this experiment I got a deeper understanding on the concepts of hydrophilic and hydrophobic. With the sand I able to get a better grasp on the what it really meant. Generally sand hydrophilic meaning that it would dissolve with water, and with the silicone spray it was interesting to see it become hydrophobic to wear it actually resisted the water. With the sand be hydrophobic it made it seem as if the water was floating on top of the sand.
Looking Inward:
Overall in this experiment I did get desirable results. All went as planned and nothing bad happened. I believe that it turned out well because I thoroughly applied the the spray and made sure that I mixed it well so that the experiment could work well.
Looking Outward:
Considering that I only had one other group member with me during the lab I still believe that I worked well with her. We didn't get distracted and made sure that we followed the procedure. Overall I believe that we performed well and did the experiment correctly.
Looking Forward:
If I could do this experiment again there wouldn't be much that I would change. I was content with my results and I learned much from the experiment. Overall there wouldn't be much that I would change.
Take Aways:
Some take aways I gained from this experiment was learning how going step by step can actually help the overall experiment. Generally in previous experiments there is something that I had wish that I could of done better. But in this experiment there was really nothing that I wish could've been done better. So the lesson learned here is the importance of really making sure that I went through the steps properly and that you should always take your time.
