In class we made magic sand. We did this to represent Ionic and Covalent Compounds. An ionic compound is when there is an exchange of electrons which creates oppositely charged ions. Ionic compounds carry cations and anions, which are considered strong bonds. Some terms involved were, hydrophobic, hydrophilic, polarity, and solubility. Each of these helped us observe the science that was going on during this experiment:
Hydrophobic: Fear of water, they separate (like oil, etc.)
Hydrophilic: Attracted to water (dissolves)
Polarity: Have a capability of dissolving other polar molecules
Solubility: A level to which something dissolves in a solvent
Materials we used:
- Glass pan
- Gloves
- Pink crab sand
- Water
- Scotch Gard Fabric Protector
For this experiment we attempted to make magic sand. There were multiple observations happening during the process. The term that my group experienced the most was hydrophobic. The reason why, was because once the sand came in contact with water they instantly started to separate. It's kind of like the idea of oil. When oil is mixed with water it instantly sits at the surface, this is because they have strong bonds. They pull back. The sand sunk to the bottom as the water rose to the top. This happened from the fabric spray which coated the sand in a protective layer, so that once you pick some up it's still dry. After a while of the sand soaking in the water the spray began to ware out and get wet.

Yes, I think we got somewhat desirable results. I worked in the beginning when we poured the water together. I think that if we sprayed the sand a little more or added less water it would work a lot better. It was our first time doing this experiment so we got okay results. My table group worked pretty well together. We all contributed to the experiment, whether it was mixing the sand or getting the supplies ready.
Some take aways from this was that I experimented to see what the reaction would be. For example we tried pouring water into the glass container, poured sand into a cylinder of water and mixed them together. We noticed that the more time it sat in water the faster the sand would soak it up. We tried multiple ways to see if that would change anything. I thought that this experiment would be more interesting to me. Although when we finished I was a little disappointed. I was expecting more to see, even though I didn't enjoy it very much It was a cool experiment to do. In my opinion I would not like to continue this experiment.
