Science at Bangor & in the News
In the second chemistry unit we will be looking at energy & particles moving. We had two demonstrations that showed us that particles can move. First, I opened a bag of popcorn in one corner of the room. After a few minutes, people that were far away could also smell the popcorn. Since the smell moved across the room, we decided that the particles had to be moving. The second demonstration used a very warm beaker of water and a cold beaker of water. I dropped food coloring into both beakers at the same time. The coloring in the warm beaker quickly spread throughout and became evenly distributed, but the coloring in the cold beaker wasn't spread out even by the end of the hour. The cold beaker actually looked more like a lava lamp. From this we concluded that not only do particles move, but they must move faster in warm temperature than they do in cold temperature. We call the particles moving from an area of high concentration to low concentration diffusion.
In Science 9, we continued to practice our measuring skills. This week we added area and volume into the mix. We made sure to talk about the area of a circle so that we could find the best pizza deal for the money. Anyone in class that day should always be able to make the most economical choice for pizza. Next week we will get more in depth in examining volume & we will wrap-up our unit on measuring.
