Help your 4th graders explore the fascinating world of plants with this comprehensive, NGSS-aligned reading passage packet! This resource provides an in-depth look at how both visible and hidden structures work together as a system to help plants survive, grow, and reproduce.

About This Resource

This "phygital" resource blends traditional print materials with interactive digital features to support diverse learning environments. Students will learn about the critical roles of roots, stems, leaves, and flowers, while diving deeper into internal components like xylem and phloem. Each topic is presented in two differentiated reading levels to support all learners.

What’s Included

Differentiated Reading Passages: Two levels of text (Simplified and Detailed) for every topic to support tiered instruction.
Spanish Translations: All reading passages are provided in Spanish to support ELL students.
Interactive Digital Features: Access via QR code to read-aloud audio, auto-graded quizzes, digital flashcards, and interactive matching activities.
Comprehensive Glossaries: Key vocabulary defined for every major section.
Writing & Critical Thinking Activities: Open-ended questions that encourage students to explain processes and support claims with evidence.
Graphic Organizers: Tables for comparing internal vs. external structures, and identifying structure-function relationships.
Answer Keys: Full answer keys for all quizzes and suggested responses for writing activities.

Topics Covered

What Are Plant Structures? (External vs. Internal)
Parts of Plant Stems: Exploring Xylem and Phloem
How Water Moves Inside Plants: The straw-like transport system
Parts of a Leaf: Cuticle, Stomata, and Chloroplasts
Parts of a Flower: Petals, Sepals, Stamen, and Pistil
Stamen and Pistil: The pollination process
What Is Inside a Seed? : Embryo, Stored Food, and Seed Coat
Internal Structures and Survival: How hidden parts work together

Learning Objectives

After using this resource, students will be able to:

Identify and describe the function of external plant structures, including roots, stems, leaves, and flowers.
Explain the difference between internal and external structures and provide examples of each.
Describe the specific roles of xylem and phloem in transporting water and nutrients throughout the plant.
Detail the process of photosynthesis within leaf cells and the role of stomata in gas exchange.
Analyze the parts of a flower and explain how they contribute to plant reproduction and seed formation.
Identify the three main parts of a seed and describe their roles in the survival and growth of a baby plant.

Standards Alignment

NGSS 4-LS1-1: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
