Heat Wave!
Hey guys….the videoconference was so cool! It is great that we have this kind of technology….many of the other teachers said that their students don’t have the access that we do to computers and technology in their classroom. We are very lucky to have the laptops and equipment that we have!
This morning after our conference I walked on the road out to meet my group. It was kind of nice just to walk and be able to listen to all the sounds around me. One thing that I heard was a peeping noise, which reminded me of the spring peepers (frogs) that we get in Maine in the springtime. I forgot to ask the scientist if they were frogs or birds. I’ll try to remember to ask tomorrow. It was really warm today and I didn’t even have to wear a long sleeved shirt, but I did find a tick on the back of my neck. Luckily, it hadn’t attached yet.
I was reading over your answers from yesterday and I have posted just a few, although many of you had correct answers and good hypotheses.
To answer a few (sorry not all!) questions you had….
**We have been working in the same area each time; they are getting data for a 16-hectare plot. Each hectare is 100 meters by 100 meters and has 100 smaller plots inside; each of those is 10 meters by 10 meters. We work in the smaller plots (10m x 10m) until we have tagged all the trees and then we move onto the next one. Yesterday my group yesterday did about 5 plots. I think we did about 7 today.
**Largest tree we measured today was a tulip poplar that was 73.3 cm DBH. Can you figure out the circumference?
**The tower that we climbed the other day had all sorts of instruments up top. There were some to collect rainwater, some to measure wind, some measured UV radiation from the sun and there were many more….those are the ones I remember.
In college, I read a book that I really liked called Reading the Forested Landscape by Tom Wessels. The book discussed how much you can tell about the history of a forest by what you find. For example, do you remember in the video I made in my backyard I pointed out the stone wall? Stone walls in New England generally mark the edge of old fields and property lines. So I hypothesized that my property used to be farmland. Then, my neighbor told me that my house was part of an old potato farm! My hypothesis was correct. So, now I have two photo mysteries for you…..what do these pictures tell you about the history of the land or tree?
Today’s Questions:
1. Photo mystery questions….hypothesize what has happened to the land or trees in the photos.
2. What are some ways that people can identify trees? Think of as many as you can and remember that the leaves are not always there!
3. Brainstorm some of the benefits of trees and forests. Check out the following two links (Maine Forests, Forest Facts) that will give you some ideas. Then find a picture (either at home in a magazine or print one) that represents one of the benefits you came up with. Attach your photo to the back bulletin board.
If you finish early watch the videos that Lynne Barden or Lesa Rohrerhave posted on their blogs! Have a great Thursday!

For the first picture we think is bear claw marks and also partially rotting. For the second picture we think that there was barbed wire that wrapped around the tree and was there for a long time. The tree maybe grew around the wire.
4 ways to tell how to tell trees apart are
-Leaves
-Seeds
-Bark
-color
Miss ya!
Picture-1. Insects or a woodpecker ate at the tree.
Picture-2. There was an old fence there and a tree grew around it.
2. You can identify it by the leaves pines and pine needles, the bark, the seeds and height.
Kaitlyn and i think that the first tree picture is an old tree that has been decaying for awhile. Then the second tree we think is sticks coming out of the tree, meaning that the sticks grew in with the trees roots and became part of it. What kind of trees are these two? some ways people can identify trees is by the type of leaves or buds the color of bark or the way the bark looks you could also tell by the size of the trees like how tall or wide they are. where it is growing like what type of area it is in.
the wire was hooked to the tree and the tree grew over the wire. and we think it was stapilizing tree or a property line of some sort
the first tree look like it shot by a shot gun with a wide spread
2. leaves bark hardwood soft wood wear it grows
1. Pic #1: I think that maybe someone marked it maybe for a purpose like property or something of that sort or maybe it could be like warped from like the weather or rain or something .
Pic #2: We think that people of a tribe or owner of a farm of some sort marked the tree using metal to show some sort of ownership or maybe it it a sign resembling something like a symbol to show other people something.
2. People can identify trees by looking at the the curves and bumps in them. Another way is looking at the leaves and looking at the shapes and colors. You can also look at the seeds they have like how you said those pointy seed things cam from a certain type of tree. You could also tell by like the bark and roots probably.
Picture #1-For this picture, we thought that There were bugs getting into the tree, because it had lots of tiny holes, small enough for a bug.
Picture #2- For this picture, we thought that an electric bolt went into the tree, and it opened it up, so they shut it with the wire. Then, the tree grew around it. Or, that it was part of a science experiment.
2. You can tell from the bark, the leaves, the hight and the width.
1.We think that the tree looks old and dried out. it also looks like it is going to die.for the second picture we think the wire is there to support the tree and not let it fall down.
2. the bark, leaves, the hight, and the thickness of the trunk.
1) We think the first tree had worms living inside of it. They were trying to get food and ate the tree.
The second tree was around wire. As it got older, it grew into the wire.
2) You can check the hight, the leaves, the bark, or the branch patterns.
picture one: We think there was a woodpecker attack!!! :)
picture two: We think that the material on the tree is a metal wire support so it would not fall down.
question two: You could identify a tree by its bark.
p.s.... we miss you!
pic#1-We think that this tree is about looking like it is going to die it has lots of holes and brownish gray and we also think that the holes got there by someone accidentally shooting the tree.
pic#2-this tree looks like it will fall down soon because it is bent we think that people accidentally hitting it and we also think it got bent by a deer or moose bumping in to it at night when someone was trying to shoot the deer or moose.
we think you can identify them by the way the they look and the color on the trees and like if there bent or not.
