Lesson 1: Plumbing of the Plant

How does a 300-foot redwood get water to its top leaves without a heart?

Xylem, Phloem, Vascular Bundle, Sieve Plate, Tracheid, Lignin.

DCI: LS1.A (Structure and Function); SEP: Analyzing and Interpreting Data; CCC: Structure and Function.

Analysis in Science: Interpreting cross-sectional diagrams and identifying structural features that support specific biological functions.

(DOK 3) Students conduct the "Celery Experiment," tracking colored water movement to identify xylem locations. They complete the "Xylem vs. Phloem Activity," comparing dead hollow tubes (water) vs. living tubes with sieve plates (sugar).

Roadside Grass: Students observe the "brown grass" phenomenon and investigate if the vascular "pipes" themselves are physically damaged or if the issue lies in the material being transported.

Many students believe that xylem and phloem move material in the same direction or that plants "breathe" water through these tubes.

Differentiation by Content:
Tiered Assignments: Create assignments with varying levels of difficulty to cater to students' abilities. For example, offer a basic level assignment, an intermediate level assignment, and an advanced level assignment.
Flexible Grouping: Group students based on their readiness levels or learning styles. This allows you to provide targeted instruction and support to different groups of students.
Choice Boards: Offer students a variety of activities to choose from, allowing them to select tasks that align with their interests and learning styles.
Differentiation by Process:
Scaffolded Instruction: Break down complex tasks into smaller, manageable steps to support students who need additional guidance.
Graphic Organizers: Provide students with visual tools like Venn diagrams, concept maps, and timelines to help them organize information and make connections.
Technology Integration: Utilize technology tools like simulations, online resources, and educational apps to engage students and provide alternative learning pathways.
Differentiation by Product:
Multiple Assessment Options: Offer students a variety of ways to demonstrate their understanding, such as written reports, presentations, models, or digital projects.
Student Choice: Allow students to choose the format for their final projects, giving them ownership over their learning.
Rubrics: Develop clear and specific rubrics to provide students with expectations and guidelines for their work.
