Objective:The children will explore the parts of a tree, and create a class tree with a trunk, branches, and leaves.
A tree is a giant plant. There are two major types of trees: deciduous and conifers. Deciduous trees grow broad leaves, whereas conifers have narrower needles. Most deciduous trees have leaves that change colors in the fall, and they eventually lose all of their leaves. Each spring, they grow a whole new set of leaves. Most conifers are evergreen, which means that, when their needles die, new ones take their place right away. Even during the autumn and winter, these trees are green.
The visible parts of a tree are the trunk, the branches, the leaves, the flowers, and the fruit. Hundreds of roots are under the ground in the soil. The trunk, like a large stem, delivers the nutrients from the roots to all of the other parts of the tree. The branches act as mini-trunks and continue bringing the nutrients directly to the leaves. The leaves “breathe” in the air through little holes on their undersides and change the sunlight into energy. The bark is a hard skin on the outside of the trunk. The bark protects the trunk.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
