All about Trees!

This January we have been studying trees.  We began by measuring around trees and talking about which were bigger around and which were smaller.  Sometimes we guessed and then checked to see if we were right by using yarn.  The next week we explored growth rings on trees.  We learned we could tell how old a tree is by counting the circles.  This week we are talking about tree roots and what they are for.  I wonder how many roots we can see on trees?  Are they always underground or sometimes can we see them above ground?  I'll let you know what the children have discovered about tree roots tomorrow!
