Overview

This 5-day series explores how materials move through living organisms, focusing on the plant vascular system and animal respiratory and circulatory systems. It integrates interactive activities, diagrams, and critical thinking to engage 7th graders in understanding biological transport mechanisms aligned with Common Core Standards.

Standards Alignment

While the Common Core State Standards (CCSS) primarily focus on ELA and Math, this lesson plan cross-links with the Next Generation Science Standards (NGSS) and Common Core ELA standards focusing on reading informational texts, writing, and speaking/listening, as Science is integrated across subjects.

Next Generation Science Standards (NGSS) Middle School Life Sciences:

MS-LS1-3: Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
MS-LS1-7: Develop a model to describe how food is rearranged through chemical reactions. (Related to how substances move through systems)
MS-LS1-6: Construct a scientific explanation based on evidence for the role of photosynthesis and cellular respiration in the cycling of matter and flow of energy into and out of organisms.

Common Core ELA Standards for Literacy in Science:

CCSS.ELA-LITERACY.RST.6-8.1: Cite specific textual evidence to support analysis of science texts.
CCSS.ELA-LITERACY.WHST.6-8.2: Write informative/explanatory texts to examine a topic and convey ideas.
CCSS.ELA-LITERACY.SL.7.1: Engage effectively in collaborative discussions.

Learning Objectives

By the end of this week, students will be able to:

Describe the structure and function of plant vascular systems (xylem and phloem).
Explain how the respiratory and circulatory systems work together in animals to move materials.
Label and color diagrams to demonstrate the levels of biological organization related to transport in plants and animals.
Integrate information from multiple sources to explain biological transport systems (CCSS reading and writing integration).

Daily Outline (40 minutes each)

Day 1: Introduction to Transport Systems

Objective: Introduce the concept of material movement in living organisms and biological organization levels.

Time	Activity	Details
0-10 mins	Hook & Brainstorm	Show a slow-motion video clip of water moving through plants and blood flow in animals. Brainstorm what materials move and why. Record ideas on the board.
10-20 mins	Mini-Lecture	Use visual aids to explain cell, tissue, organ, organ system, organism organization with examples in transport. Introduce vascular system in plants and animal circulatory/respiratory basics.
20-35 mins	Worksheet Part 1: Label & Color	Students receive a worksheet showing the levels of biological organization. They label parts and color each level using a color key. Emphasize plant and animal examples of where transport occurs.
35-40 mins	Exit Ticket	Three-question quiz: Define vascular system; Name 2 transport materials in animals; Levels of organization from smallest to largest.

Day 2: Vascular System of Plants

Objective: Explore xylem and phloem functions and the transport of water/nutrients.

Time	Activity	Details
0-10 mins	Quick Review	Recap Day 1 via Q&A. Show diagram of plant vascular system.
10-25 mins	Interactive Activity: Capillary Action Experiment	Set up simple celery stalk in colored water to observe xylem transport visually over class time. Students record observations in science notebooks.
25-35 mins	Group Discussion & Diagram	Groups discuss what they saw and label plant vascular system diagrams in worksheet.
35-40 mins	Write-Think	Students write 2-3 sentences explaining how xylem and phloem work, citing their own experiment (CCSS W.7.2).

Day 3: Respiratory System in Animals

Objective: Understand how animals inhale oxygen and exhale carbon dioxide.

Time	Activity	Details
0-10 mins	Hook Video	Show short clip of breathing in humans and other animals. Clarify why respiration is essential.
10-20 mins	Diagram & Label	Provide respiratory system diagrams; students label all parts and use different colors to denote oxygen in vs. carbon dioxide out.
20-30 mins	Paired Reading	Students read a science passage describing gas exchange in lungs. Use text annotation strategies to highlight key information (CCSS RST.6-8.1).
30-40 mins	Turn & Talk	Students discuss how respiratory system connects with circulatory system. Teacher guides with scaffolding questions.

Day 4: Circulatory System in Animals

Objective: Learn how blood circulates to transport oxygen, nutrients, and waste.

Time	Activity	Details
0-10 mins	Visual Model	Demonstrate blood flow using colored water in a balloon model simulating heart and vessels. Students observe flow direction.
10-25 mins	Reading & Note-Taking	Informational text about human circulatory system (heart, arteries, veins, capillaries). Students take structured notes. (CCSS RST.6-8.2)
25-35 mins	Diagram Label & Color	Circulatory system worksheet section: students label the heart parts and color pathways (oxygenated vs. deoxygenated blood).
35-40 mins	Quick Write	Write a short paragraph describing how the respiratory and circulatory systems work together (CCSS W.7.2).

Day 5: Synthesis and Application

Objective: Solidify understanding and express knowledge in creative and analytical forms.

Time	Activity	Details
0-10 mins	Review Game	Use quiz game format (like Kahoot or team quiz) reviewing key concepts from the week.
10-30 mins	Project: Create a Transport Model	Students choose to create either a 3D model, detailed drawing, or digital slide explaining material transport in a plant or animal system. Include labeled parts and flow arrows. Encourage creativity (art supplies or tablets).
30-35 mins	Presentation Prep	Practice explaining their model with a partner. Use their notes. Emphasize clear, scientific language (CCSS SL.7.4).
35-40 mins	Exit Reflection	Write a 3-4 sentence reflection on what they learned and found interesting. Reflect on the importance of transport systems for life.

Worksheet: Biological Organization - Label & Color

Instructions:

Label each level of organization (Cell, Tissue, Organ, Organ System, Organism).
For plants: show examples (e.g., xylem = tissue; leaf = organ).
For animals: show examples (e.g., alveoli = tissue; heart = organ).
Use the following colors:
- Cell = Blue
- Tissue = Green
- Organ = Yellow
- Organ System = Red
- Organism = Purple

Worksheet Sections:

Diagram of a plant stem section showing xylem/phloem area.
Diagram of animal lungs and heart with tissue and system labeling.
Small text boxes with definitions asking students to match labels.

Teacher Notes and Tips

For large class of 200, divide students into smaller groups for activities and discussions. Utilize multiple spaces if possible.
Encourage peer teaching and collaborative learning for mixers with this large group.
Use graphic organizers and sentence starters during writing tasks to support all learners.
Use videos and hands-on experiments to engage different learning styles.
Consider formative assessments during exit tickets for real-time data on student grasp.
For assessments, combine diagram labeling accuracy with written explanations to evaluate understanding.

This week-long plan balances core science concepts with CCSS-driven reading, writing, and speaking skills, providing rich, interactive learning about how plants and animals move essential materials.
