Tree Rings

This week in science students learned about tree growth rings.  The rings in the tree tell scientists how old a tree is and also gives them some clues about the season conditions for each year it was living.  We learned that the dark rings are called "latewood rings" and the light rings are called "earlywood rings".  These give scientists some clues about the rain and water for each year of its life.  The thicker the earlywood ring, the more rain occurred the summer of that year!
