Build a Tree

Lesson:

Activity Description: 

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.  This illustrates how the tall rain forest trees adapt to support a huge trunk and heavy branches, while also sending their roots out instead of down.

Objective: 

Students learn how the structural components of trees help them stand up under rainforest conditions.
