Dec 19th I was absent! However the class worked on a conservation of mass lab. They took the mass of a denture cleansing tablet, a beaker, some water, and a ziplock bag. They then placed the water and the tablet in the bag, quickly sealed it and observed the reaction.
Finally, they weighed the bag, water and dissolved tablet, and then tried to determine if mass was conserved.
Dec 22nd we coated pinecones with molten wax, then sprinkled metallic salts on them. These can be thrown into wood burning fireplaces to create different colored flames. We also received our elements project grades and watched some of the elements commercials.
