Our Observations
There are four oaks on the spot of our observations in the front garden near the dwelling house. Their age is more than 20 years. The height is about 4-5 meters. One of the trees keeps the leaves on its branches, others throw them down.
The appearance of the oak which kept its leaves is as follows: a leafy curly top (squeezed from sides) and tortuous knots. There are many branches moving away equally aside. The trunk is dark-grey covered with a thick crust with deep cracks. The oak is well proportioned, high, is bent forward to the house. The leaves are rolled up, dry and yellow-brown. The edge of the leaf is wavy and figured. Some acorns were found below in the fallen leaves.
There were some signs of life: a fly was sitting on the leaf of the oak (see the photo of the leaves when you roll your mouse over the photograph of our class) and two ants were crawling along the trunk.
At the moment of the observation the weather was cool, dry and cloudy. Observers wore caps, warm jackets and boots.

Here are two pictures of our class with our winter tree:
Our Oak in Winter
On our oak you can see some dry yellow,
rolled up leaves but they became wore dreary, pale as if they are faded.
The trunk is covered with hoar-frost. We found a blackened old branch
among living branches of the oak with small acorns.
The depth of the snow cover around the oak is thirty centimeters. After
digging up the snow we found several acorns. There were no signs of
life. We didn't see any birds except their tracks: impresses of crows
or magpies. We also saw the seeds thrown about everywhere because of
the rack on the tree.
We were warmly dressed: jackets and fur coats, fur shoes, mittens and
warm scarves.
The oak seems to sleep.

Description of the Oak in Spring
NOTE: This description was written by students in Russia. They speak Russian as their first language. Click here to see this written in Russian.
We stated that on one of the four trees some last-year leaves were found
but they were rather pale and colorless. On the contrary, the crust became
more colorful. The fallen last-year leaves blackened and obliterated.
They got wet because of the melted snow. We found several cracked acorns
under the oak but their caps lay separately from the fruit. Pointed stalks
of the new grass appeared among four trunks under the oak.
On the ground Lida found a cap of the acorn with a white film and sleeping or died beetle. At the bottom of the trunk Semen saw a spider. Neither other living- beings nor birds were seen.
The observers were dressed in light jackets,
boots or shoes but not all of them wore hats.
