FOCUS: Winter trees may look dead, but concealed in their buds are the beginnings of next year’s shoots, leaves, and flowers. Food is scarce in our winter woods, and for many animals the twigs, buds, and bark of dormant trees provide a welcome source of nutrition. Animals have no trouble recognizing which trees make the best meals, but for us identifying trees when their leaves are gone requires a close look and attention to detail, the skills of a good detective.
INTRODUCTION: TWIG QUESTIONS
Objective: To begin to explore and ask questions about trees in winter.
Ahead of time, cut twigs from a variety of trees including some that have alternate branching (e.g. elm, beech, oak, poplar) and some that have opposite branching (red maple, sugar maple, and ash). Make sure to cut twigs so they are long enough to show at least two years’ worth of growth. With maple and ash twigs, pick those that show opposite branching rather than just opposite bud scars, as these can be hard for children to see. Pass out a twig and a magnifying lens to each child. Ask them what they notice about the twigs. Also, what do they wonder about them? Make lists of their observations and questions on the board. Collect the twigs to use again later for Twig Dress-up and the journal activity.
Materials: variety of twigs showing at least two years of growth (one for each child), magnifying lenses.
A BRANCH THROUGH THE SEASONS
Objective: To model the yearly cycle of growth and change in a tree branch.
Divide the class into groups of six to eight children with an adult leader. Give each child a Branch through the Seasons card showing a stage of twig development on an American beech branch. Continue reading Trees in Winter – Activities
