How old is that tree lesson plan
It is a very vulnerable stage of development where stresses such as insects, viruses, and excessive water can end its life.
When a young tree grows a few inches, it is called a sapling. It will begin competing for resources such as nutrients and sunlight to maximize its growth. This is the ideal stage to transplant a tree from a seedbed to a location where it will develop on its own.
This stage contains a tree's prime years of reproduction. A mature tree produces flowers and fruit that will bear new seeds that will be dispersed back to the ground, continuing the cycle. In addition to producing fruit for consumption, mature trees have trunks that are used as lumber. As the tree reaches the last stage of its maturity, it becomes more susceptible to diseases and other stresses such as insects, wild animals, and viruses. It does not have the ability to compete well with other plants or trees around it that are stronger and younger.
The tree will eventually become a snag, which plays an important role in returning to the ground the nutrients it absorbed during its life.
To see the beginning stages of an oak tree's life cycle, watch acorn underground to oak seedling time lapse filmed over 8 months , from Neil Bromhall:. Different trees have different characteristics but their needs are almost always the same in every stage of their development. If you are planning to grow a tree, you must evaluate the environmental conditions carefully and make sure the young tree will have all that it needs.
It might be helpful to talk with an arborist tree doctor or someone at your local nursery to find out which tree is best for your area.

Measuring the Height of a Tree Explain to students that they can measure the height of a tree in the following ways: Stand at the base of the tree, and hold a ruler straight out in front of you in a vertical position. Close one eye and back away from the tree until you reach the point at which the ruler and the tree appear to be the same size.
Stop and have a partner measure the distance between the tree and the ruler. That is the approximate height of the tree. One of the simplest ways to measure a tree's height requires a sunny day. Pound a stick or dowel into the ground. Measure the length of the stick above the ground, then measure its shadow. For example, the stick might be 3 feet tall; its shadow might be 2 feet long. Now you know that a 3-foot stick casts a 2-foot shadow.
Measure the shadow cast by the tree. Students in the upper elementary grades and above can figure out the height of the tree by making an inclinometer and using it to calculate the tree's height. Assessment Students share how they arrived at each of their calculations. You might have students write in their journals explanations of the math processes they used.
