A student (N.C.) sent me this neat video based on the If the World Were a Village website. I plan to show it to my environmental science class because we’ve been talking about human population recently.
The Fulton School has a wonderful music program, so I’m hoping that this video, about how Paraguayan children living in a slum on a landfill have recycled classical instruments out of the trash, resonates with some of my environmental science students.
Of course, we’ve seen other instruments invented out of discarded trash. The BBC has a brief history of the steel pan, but Trinbagopan.com has an much more detail. On the other hand, I prefer my history in a musicalform.
This nice little video combines a bit of physics, chemistry, and biology as it discusses how bubbles form in champagne: the gas is carbon dioxide; carbon dioxide forms from the fermentation of sugars by yeast — it’s a byproduct of the reaction that produces alcohol; the bubbles form at tiny flaws or bubbles in the glass (so you can put in tiny flaws to control where the bubbles form); the bubbles rise because the gas is less dense than the liquid around it; and the bubbles expand as they rise because the pressure of the liquid becomes less and less the closer to the surface you are.
Empathy is seeing the world through the eyes of others. Adolescents tend to look inward, not outward, but empathy is the basis of morality, so exposure to others and other points of view is an important element of their education. I find the following video interesting (much like the Bright Eyes video) because in its hints at so many hidden messages and meanings. It provokes thoughts about who these kids are, what is life like for them, and how do they see the world.
Note: David Brooks argues that while empathy orients one toward moral behavior, it’s really sacred moral codes that convert that orientation into action.
