Though people disagree on the scientific evidence and what it means, I agree with the majority of the scientific communities throughout the world including organizations such as the National Wildlife Foundation, National Geographic, NASA and NOAA. They all agree that global warming is indeed something that we need to worry about for ourselves and the future of our world. If we do not make changes now to what we are doing to our world then our polar ice caps WILL melt. According to the National Resources Defense Council this will result in rising ocean levels of as much as three feet by the year 2100. In the United States this would results in massive flooding of approximately 22,400 acres of land mostly in the southern Atlantic region. Another result of the polar ice caps melting is temperature change. When the ice caps melt they will no longer be cooling the wind flows that normally go across them, which means cooler temps and affected food production (2005).
The first question I would pose regarding this Science Inquiry Experience is why the results vary per person? I think a few more specific details on the experiment would have helped. Such as how many ice cubes to use, how big of a bowl/glass, etc. I completed my experiment more than once in order to verify my results since I was so unsure about the exact procedures.
How could more technology be involved in the experiment? Could we have some specific links to unbiased documents that give the facts for both sides? Or videos that explain the science at work?
The last thing I would like to say about this experiment and on the subject of global warming is to have people take a look at some of the simulations available that explain the science at work. For my colleagues,I have included a few links to interesting sites, simulations, and games in the bottom right corner of this blog, under links.

I love the use of power point presentations. I have one for each of my benchmarks. I try to tell a story that connects the benchmark to real-life. I usually use some made-up family member to narrate the story. This makes it fun and interactive with the students.
ReplyDeleteFascinated about the interactive sites. The National Geographic site intrigued me the most. this site would probably be one I might to integrate technology into this lesson.
ReplyDeleteCharity, question for you. Any suggestions in introducing this concept to elementary level students grade 4 - 5?
Mark, I suppose it would depend on how in depth you want to go on the subject. Coming from a Jr. High perspective I know I could go pretty in depth and explain the gasses in the atmosphere. But at the 4th and 5th grade level I am not certain they would understand that concept. So I suppose you would probably just introduce it on a community level? How does the world view GW? Then go into some of the causes and results and discuss the science behind them without going into that detail of the gasses? I am sorry, I really don't know, just some ideas for you.
