In the Webelos adventure, Into The Woods, requirement 5 has the scouts looking around their homes to find items that are made out of wood and share their findings with their den.

Have you ever stopped and counted the rings on the log your about to place in the campfire? 

n the area that I live in, there are two main groups of trees.  We have deciduous (trees that lose all their leaves for part of the year), and Evergreen (trees that do not lose all their leaves at the same time).
