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.
This lesson was designed for children to take all of the information they have been learning about trees a step further. Now that they have learned what parts make up a tree, what function each part serves, and how to collect and identify different parts of a tree, the focus is going to shift to factors that might influence plant growth.
Using knowledge of tree parts gained in Lesson 1, students collect tree parts and use them to identify the tree using specified books. Students then create a display and present results to the class.
Students recall everything they know about trees in science journals and share in a class discussion. The book Tell Me, Tree: All about Trees for Kids, by Gail Gibbons is then used to begin a discussion about the parts of trees. Students then revisit their tree knowledge and formulate questions for future learning.
