Group 2 blog #2

Our metal is iron and our mineral is calcite. Our group believes that mass and conductivity are the most reliable because they are the most helpful in our identification process. Conductivity was good because it was a binary so there was not much error. Mass used the scale so was more accurate than our observations. Density was not so helpful because the scale was hard to read. Additionally, qualitative observation was important because it helped us identify both mineral and metal when our data was a little off compared with the tables.

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.
