We began our tree study unit this week. We've been talking about the annual changes in a tree and the life cycle of a tree, referring back to our study of leaves and the changing of seasons and seeds. We talked about the parts of a tree and scavenged materials and made a group sculpture of a tree including roots, bark, branches and leaves. We spent one day talking about roots, and we dug holes and buried our feet and calves in the dirt and felt how being rooted in the earth helps a tree balance and reach high. We did an activity called "meet a tree," where the children are blindfolded (those willing anyway), and get to know a tree by using their senses of touch and smell and by being quietly present and observant. We made bark rubbings. Tomorrow we will do a capillary action celery experiment with colored water, and make some ants on a log for snack.
