Group #3 Metal and Mineral

Initially when trying to determine our metal and mineral we believed that conductivity, solubility, and whether or not the material would melt were going to be big factors to help us narrow down our choices. Most of our predictions were correct when we conducted the experiments. Once we went through the experiments conductivity and density were the biggest factors in determining our metal. With us knowing that our metal was a conductor we were able to narrow our options of materials down to seven different choices. The material Molybdenum was the only one that fit our observed density (10.55g/ml) and was also a conductor. Throughout our experiments when determining the mineral we felt solubilityand hardness were the most important factors in discovering what mineral our group had. We determined it was Gypsum due to the fact that our unknown material had the same score on the hardness scale as Gypsum. Also the material was insoluble which helped us narrow down our options. Finally, our unknown mineral had a similar appearance to that of Gypsum.

Ocean acidification is important because it impacts biodiversity. A falling ph level has detrimental impacts on species that build shells or skeleton based on carbonate. For example, tropical corals. Hence ocean acidification destroys ecosystems, resulting in the ultimate disappearance of certain species. The computer generated evidence predicts that if the carbon dioxide emissions continue to rise exponentially, this will result in the drastic increase in the ocean ph level. The levels of PH are predicted to rise as much as they have in the past 300 million years in the next 1000 years. The computer models used past historical and geographical evidence to see what the natural rise would be and compared it to the rate at which ph levels are rising today. It would be difficult for nature to compensate for these damages. Consequently, resulting in further reduction on the marine biodiversity, specifically, coral reefs.

Group 5: We misidentified the metal as Iron, when it is in fact Zinc. This occurred because we calculated the volume incorrectly which thereby translated to the wrong density. In addition, we observed that the metal did not melt. Our metal also fell apart onto the table which could have been a sign of possible meltage. As for our mineral, we believed that it was quartz, when it was actually Fluorite. We did not believe it had dissolved into the test tube; however, it in fact was slightly soluble. The largest error we made, which would have helped us determine correctly what the quartz and the metal were, was incorrectly calculating the density. If we would have done this part correctly, we likely would have determined the correct mystery materials.
