As a fun summer holiday exercise, learn how to determine the age of a living tree.

A SIMPLE mathematical equation can be used to determine the age of a tree.

Throughout the United Kingdom, huge historic trees can be found, many of which have been standing for hundreds of years. If you’ve ever wondered how ancient these towering trees are, there are a few different ways to find out.

No, this isn’t an urban legend; you can actually determine the age of a tree by counting its rings. During the spring and summer months, when the tree is at its most productive, each tree grows a light ring of new growth on its trunk.

When the growth process slows down in the autumn, a darker, narrower ring forms. One light ring and one dark ring equal one year of a tree’s life.

When the temperature, as well as the amount of rain, is just right for the tree, it will grow quicker and form broader rings. If the conditions aren’t optimum for growth, trees will develop at a slower rate, resulting in smaller rings.

If you ever come across a tree stump, it’s a terrific way to get the kids involved in counting tree rings (also known as growth rings). However, make sure you’re only counting the bright or dark rings, not both, otherwise you’ll be overestimating the tree’s age.

In addition to dating them, scientists can use wood to acquire data on temperature and atmospheric conditions at various times in history.

Scientists don’t even need to cut down trees to get these readings from trunks; instead, they can use an increment borer to carve out a small chunk of wood, about the size of a pencil, to observe the results. This will not harm the tree.

If you don’t have an increment borer at home, like the bulk of us, you can use simple math to figure out how old a living tree is.

It won’t give you an exact age for the tree, but it will give you a pretty good estimate. For this project, you’ll need to know a few mathematical terms, including:

Circumference: The measurement of a circle’s circumference. Diameter: The width of a circle, or the distance from it. “Brinkwire News in Condensed Form.”
