Introduction
December 8th, 2008
Today we had a very full day. We had a presentation by Dr. Bert Drake who talked to us about climate change to start off the day. It was an excellent talk and I will share some of his information with you when I return. Next, we meet with the scientists we will be assisting. We took a short walk in the woods and learned a little about the trees we will be identifying. The photo shows the seeds of a tulip poplar tree, it reminded me a little of a pine cone because all the seeds were layered together.
As we were looking on the ground for other seeds I thought I found one but as I picked it up I realized it was actually deer scat! I quickly dropped it!
Then, we learned how to measure diameter at breast height (dbh) as well as how to identify where the trees are in the canopy. We practiced doing this so we are ready to go out to the plots tomorrow and get started collecting data. I hope you are all doing well!
Today's Activity
I would like you to go to the EPA’s website. I know that you learned about the carbon cycle last year, but I would like you to watch the carbon cycle movie & take the quiz at the end. Use that information as well as the internet to answer the following questions with a partner. Post your answers to the blog - only one post per group.
1. Where is carbon found?
2. What is a carbon sink?
3. How do you think this (carbon cycle & sinks) connects to the research being done here?
4. Feel free to ask me a question!

Carbon is found in soil, plants and trees, rocks, and others.
A carbon sink is a forest, ocean, soil and atmosphere that tends to take more carbon than they emit. Oceans and Forests are 2 examples.
We think this connects to the work you are doing because it effects the forests.
What amount of trees do you think that you will get done over the course of the time that you will be there.
carbon is found plants and trees use carbon dioxide and land and water.
a carbon sink is reservoir of carbon that accumulates and stores carbon for an indefinite period. the main natural sinks are absorption of carbon dioxide by the oceans and photosynthesis by plants and algae.
because the trees and plants have the carbon in them.
How many trees have you seen that are not here?
What is your favorite kind of tree?
1. Plants, animals , and humans.
2. Carbon sinks are natural systems that suck up and store carbon dioxide from the atmosphere. Two examples are a microwave factory...

Also an old growth forest is a good carbon sink.
3.We think it is connected by the trees that you are studying because it involves carbon.
4. The question is why are the seeds you showed us so big?
1-carbon is found in trees, rocks, shells, the atmosphere,the ground,and dead animals.
2-a carbon sink is a reservoir of carbon that accumulates and stores carbon for an indefinite period. ex. absorption of carbon dioxide by the ocean, photosynthesis by plants and algae!
3- carbon comes from trees so that is how it connects with the research being done here=]
4-what kind of different trees do you have that we don't?
Carbon is found in the atmousphere , Fossils Fuels, Part of the soil that is discovered in bodies of water, Carbon is stored in plants and trees.
A carbon sink is a resevoir that can absorbed carbon dioxide from the atmousphere. EX soil, peat and ocean water
There is carbon in trees when they decompose into soil. When the leaves fall from the ground they are brown material which contain carbon.
What is the big lump on the tree for? What is the oldest living tree there?
1.picture#1-we think it was ants living inside the tree.
picture #2- the vines that grow in to the tree.
2.leaves,pine needles,sap,size round.
