Can you tell how old a tree is?

You certainly can. Every year a tree grows a new layer of wood. The new wood makes a ring around the old wood. If you count the rings, you know how many candles to put on a tree's birthday cake.


Counting the rings
You don't have to cut a tree down to tell how old it is. Tree surgeons drill a hole in the tree and pull out a small piece of wood. Then they count the rings.


HA ha ha!
What makes a tree noisy?
   Its bark!


Chief tree
The biggest living thing in the whole world is a sequoia tree in California. It would take 12 grown-ups holding hands to form a circle around it.


Terrific tree facts
  • A large oak tree has about 250,000 leaves on it. Every single one will drop off in the fall.
  • Tree roots grow thicker and longer every year to support the tree as it grows.
