For this experiment we made Kinetic Sand and the concepts that went into it. Such as Ionic Compounds, Covalent Compounds, Hydrophobic, Hydrophilic, Polarity, and Solubility. Ionic Compounds are polar: something takes, something gives. Covalent Compounds are the sharing of electrons. Hydrophobic means the element is non-polar. Hydrophilic means that the element is attracted to water. Polarity is something magnet like. Solubility is the level to which dissolves certain things. During this we first poured pink sand then, green sand to make a mix of sand. We shook it then had it sprayed with silica spray, then we shook it some more then added more silica and we continued this process about five times. We then poured water onto it to see if it was non-polar, it turns out that my groups sand was half working. What I mean is that half the sand was polar and the other half was non-polar which means it only half worked. I liked my group I feel we shared the work equally and this lab wasn't all that complicated it was quite boring at times. I don't know if I would actually do this lab again it wasn't very exciting and quite boring at times, but if I had to do it differently, I would put less sand and more silica spray but I would probably use a different material than sand to stick to the silica spray better. As I said before I didn't really enjoy this lab all to much I thought it was really boring at times, it was mostly going back and forth between getting the sand sprayed and crushing the sand.
