To start to put together what students know about plants, students will determine which ninja assassin they should hire to kill off an offending tree. Students will collaborate with each other to discuss different ways to kill a plant, and uncover the importance of the phloem through diagrams, guided notes, and online interactives.
Then, students will return to the task at hand, and determine the best course of action. In this lesson, we start to mention photosynthesis, but only on a surface level. This lesson was designed more for cooperative learning, high engagement, class debate/discussion and higher level thinking on topics they are already familiar with.
In determining the best way to kill a tree, we can also determine if there are holes in their learning, or if we need to back up and do a quick mini lesson before moving on-- the graphic organizer where kids describe how the plant actually dies is a GREAT check for understanding, as are their analogies in the do-now.
A do now-- students create an analogy based foldable about plant parts

Guided notes about phloem vs. xylem
Homework (comparing and contrasting xylem vs. phloem)
Student friendly objectives:
I will be able to compare and contrast xylem versus phloem.
Using what I know about how plants live, I will analyze the best way to kill a troublesome tree.
I will explain where plants get their food from and how photosynthesis helps
Xylem, phloem, sap, water, stem, leaf, stomata, carbon dioxide, oxygen, roots, photosynthesis
