Thing 19

The podcasts that interested me had to do with wind turbines and CO2 sequestration. I had given articles on each of those topics for my students to read when we dealt with alternative energy. The podcasts I found were short enough to use in class and are good stand alone spots of information and excellent sources of follow up or even as prefaces to the articles I gave them. I thought it may be timely to show as a follow up for my students since Earth Day is coming up. So those two video casts I found on Science Fridays. Here are the links: this one is about wind turbines, comparing individual residential sized turbines to gigantic ones that supply thousands of homes:

Wind Turbines: Size Matters

The next one is about carbon dioxide sequestration:

Stashing CO2 In Rocks

Science Fridays - I would definitely subscribe to it.
I also liked Scientific American's 60 -sec podcasts, especially meaning useful to my classroom were

Engineered Virus Harnesses Light to Split Water

We will be studying light soon and they have studied the four ways that all waves may interact with objects and absorption is one of those ways.
