|Sample of coquina|
This module was a great reminder about the eons of natural carbon sequestration that has been taking place since the dawn of life on this planet. I was amazed to learn how much life has changed the atmosphere and how life and the atmosphere have evolved in unison. In light of how much carbon has been sequestered, this makes a lot of sense, though it's not obvious without being pointed out.
The video about Inuit observations of climate change reminded me of discussions with villagers, a few years ago, about how the winters along the lower Kuskokwim just weren't as severe as they were 20 years earlier. One of my last years in Tuluksak, the mercury dropped below freezing in early October and didn't get above freezing until late March. All of the older villagers said that was how winter was supposed to be. It was the only such winter that I experienced, there, in five years.
Extend and Evaluate - How can I use this week's resources and how useful, insightful or relevant are this module's information resources to me?
I will also use the video Ingredients for Life - Carbon in my Physical Science classes when we touch on organic compounds and why such a vast variety of carbon-based compounds exist.
The video Global Warming: Carbon Dioxide and The Greenhouse Effect shows a great demonstration of how effective carbon dioxide is when it comes to absorbing heat energy. It's a great visual when the infrared image of the scientist's face disappears behind a chamber of carbon dioxide.
The Capturing Carbon clip will be a great motivator when it's time to put on a science fair. How great is it that the scientist was able to put his daughter's project into actual use?
Three colleagues and three comments
- I agreed with Alison's comment about how amazing it is that the lowly parrot fish can create all that sand in the coral reefs. It'll give me pause the next time I curl my toes into the coral sands of Hawaii.
- I enjoyed Kathy's photos on last week's blog.
- Marilyn's blog reminded me how powerful the images on the Information is Beautiful website are. She also mentioned a song by Tom Lehrer that I, too, play for my classes when we study the elements.
