FC: Major Observation Project of a River Birch Tree
1: By: Jane Herendeen
2: This is a River Birch. According to the Virginia Tech's web site, its' common name is the Bitola Nigra. It was planted by my husband in 1998.
4: The Virginia Tech's web site says that the River Birch could live between 20 and 40 years.
7: There were 16 veins on each side that ran diagonally down the leaf until they met in the center.
8: Some Qualitive Observations: Terminal bud Shaggy bark on trunk Smooth bark on branches tan to dark brown in color Overall color is cinnamon
11: By March 13th 2010, the tree had developed some catkins. They are 3 pronged and are 6 cm in length. Not only is it a tree that provides oxygen, shade, and homes to many of natures creatures, it functions as a bike rack for an eleven year old.
12: I brought some freshly cut branches on January 22nd 2010 to see if I could force start them. They did start to grow. By March 13th the branches had leafed out. Unfortunately, they had died by April 15th. I could see that the cut ends had developed a film which I cut off. However, that did not help. Here the cat does her own scientific inquiry.
13: This is the first thermometer that I used. | This is the second thermometer that I used.
14: The tree leafed out on April 19th
16: My Insights Doing these tree observations have shown me that science does not need to be as formal as I once thought. I would have never have thought that I would be conducting such an elaborate experiment in my own yard. Contrarily, I have found that science is fun and can be done anywhere at anytime. I
18: 1st and 2nd Grade Classroom I would use my book with my students by reading it as a literature and science connection to engage them in an activity for the nature of science and technology standard, the scientific thinking standard, and more. I could introduce them to the idea of measuring, counting, and observing, by showing some of the things that I had measured, counted, and observed. My book would be a way to introduce them to the reasons we need trees, and that they provide homes for natures creatures.
19: After my students had conducted their own observations form a science center in my classroom, and had written a journal. I would have them create their own mixbook from their journal entries.
21: Answers to I Wonders . . . | The leaves are 2.5 cm, the size of a quarter. | According to the USDA web site, the sap can be fermented to make beer or vinegar. http://USDA.gov | The Living Memorials web site says that this tree was used for medicinal purposes by Native Americans.
