Fourth Day in the Field
We climbed a 120 foot meterological tower! Up top, scientific instruments measure rainfall, light, carbon dioxide levels, wind, how clear the air is and Uvb radiation.
UVb radiation, the type responsible for giving you a sunburn, can cause large changes in the aquatic environments in the Chesapeake Bay. Uvb data has been collected here for the last 30 years! That’s longer than anywhere! Another neat fact is that all of the instruments connect to computers at the bottom of the tower to record information constantly.
We were higher than the trees up there! The tower shook a little when the wind blew, but it wasn't too scary! Above is a picture of a solar panel with spikey plastic pieces on top of it. What do you think the purpose of the plastic pieces is?
Our research team went to different areas of the forest to collect data on rainfall today. To do this, scientists use a tool called a “rain gauge.” Nancy Khan, explains in the video below.
Also one of my other team members, Kate, posted a great video that goes into more detail on our tree measuring process. To see it go to her blog here:
www.earthwatch.org/lff/shannon
The video posted a few days back and is listed under her “Collecting Tree Data” headline. Please go and check out the blogs for all the other teachers here with me on my team. There's some great videos and pictures to see. To do this, after you click the link to my blog on the PS 132 website and my picture and bio come up, select the "Visit the Earthwatch Institute Web Site" option instead of "Visit my Blog" and then select the "Meet the Team" tab.
Time has been going by so fast out here! We only have one more day left in the field. Tomorrow we will see some sad realities in the forest: deforestation. (Look it up or infer the meaning...!)
Thank you again for the awesome feedback! I miss you!

Dear Ms. Cahn,
I am one of Mr. Lewandowski's students. I was wondering if you could answer a question for me. How does a cell turn sugar into energy?
Dear Mrs.Cahn you are brave to go on that building I read that you got a little scared when the wind blew!
I think the spikes are plastic long stems used for.so people don't play around with it.
Dear Ms. Cahn remember the weather there yesterday. What is the weather there now. The weather here is 34 degrees.

Mrs. Cahn,
You are quite the explorer! It is amazing to read about your experiences each day. The school is all a buzz over your blog. This is truly an experience we will all remember and learn from. Thanks for sharing it with us.
Enjoy!
Mrs. Santoro
Dear Ms. Cahn,
We have some ideas about what the spiky things are. Gianna and Olive think it has to do with reflection and gathering data. Beau and Alexis wonder if it's an electrical energy source or a weather channel. Dev thinks it could be for sending heat or gathering heat. Wes thinks its to keep the birds off. Theresa thinks it could take a scan of the birds. But Ciara and some other deep thinkers realized that the bird poop would mess up the solar panels.
Dear Mrs.Cahn,
How does an instrument collect carbon dioxide levels?
Dear Mrs.Cahn,
How does an instrument collect carbon dioxide levels? And how do you get the data?
Dear Ms.Cahn
I am wondering what that thing is that looks like a tube is a thing that collects power or sends power to the solar system or maybe it is something that gives clean air to the earth
Dear,Mrs.Cahn
I was wondering what that gun like thing was on the tower. I have a idea what the spike thing is posibly a eletricle energy sours and I know what the plastic thing was a soler energy sours.
The spikes are for how the wind is blowing. Eduardo
What kind of changes can Uvb radiation cause?
Why doesn't somebody clean up the mess from the deforestation (recycle, use as fertilizer, spread it and let new life forms grow, etc.)?
Does the association help to plant trees to help counteract global warming?

P.S. If everyone knows that deforestation, and polluting is bad for the environment, and the Earth as a whole, then why do they still do it?
Hello Ms. Leichman Chan I am Alex Luu form aiea high school, a student of Mr.Lewandowski
How big was the forest?
When you climed up the 120 foot meterological tower, was the veiw nice?
I hoped you enjoyed your trip?
Can we create a program that makes companies who do deforestation plant trees to replace the ones they logged?
Can there also be a program to make sure they(the companies)clean up and recycle their mess?
Can we ban deforestation(and find a wood substitute to fill in for the logging industry)?

P.S. Is there more we could do to help the forests, and individually do our part to help reduce global warming?
