A portion of the class will be outside, so participants should dress accordingly.
Life Cycle of Trees
|Title||Life Cycle of Trees|
|Offered||April - May|
|Length||1 hr. 50 minutes (time in the Exploration Hall included)|
Preparing for this Class
This class begins with an indoor discussion of the life cycle of a tree, including how physical growth and change are natural parts of the tree life cycle. Students will enjoy seeing a classmate “dressed” up as a tree as we explore the major parts of a tree and what trees require to survive and thrive. After this students with their own class will rotate through two activities.
- Inside the classroom students work in groups as they become “tree-tectives”. They will use dichotomous keys as they work to identify 10 local trees using leaf and seed examples.
- Outside students will hike through the woods where they will look for examples of the different stages of the tree life cycle, i.e. seeds, saplings, healthy mature trees, trees in decline and dead decaying trees on the ground.
