Science at Bangor & in the News
In chemistry we continued to explore the idea of density this week. In addition to applying what we learned mathematically, we investigated if boys or girls were more dense. Student volunteers hopped into a (clean) garbage can full of water so we could determine their volume by how much water they displaced. The volunteers also told their classmates their mass so we could then calculate their density: amount of mass for every milliliter of water displaced. For a video, check out my Twitter feed. The week wrapped up by experimentally determining the density of the gas that Alka-Seltzer produces when dropped in water.
Science 9 started a new unit this week. We started by using everyday objects as measuring tools, which works as long as the objects are standardized. Unfortunately, most objects (paper clips, pens, pencils, etc.) are not always standardized. We began working on converting measurements in one unit to a different unit and will be practicing this skill throughout the year. We left off by beginning to look at the history of measurement systems and will be using that as a starting point to enter the metric system. Both classes had a busy week between what we learned and the strange schedules on Wednesday (count day assembly) and Thursday (PSAT/practice SAT). I'm looking forward to a regular week this week and the beginning of Academic Wednesday. If anyone is having difficulties, please come see me on Wednesday morning during the academic hour!
