How Water Moves Inside Plants

About this printable How Water Moves Inside Plants science reading passage, NGSS-aligned (Grades 3-5)

This 250-word reading passage introduces fourth-grade students to the concept of water transport in plants, aligned with NGSS 4-LS1-1 and the Disciplinary Core Idea LS1.A: Structure and Function. Students discover how plants have tiny tubes inside their stems and roots that pull water from the soil all the way up to the leaves, working like a drinking straw. The passage explains how water carries nutrients from the soil to every part of the plant, emphasizing why this internal system is essential for plant survival. Written in age-appropriate language for Grade 4 readers, the passage avoids advanced terminology like xylem and phloem, instead using simple analogies and everyday examples. The content includes audio integration for enhanced accessibility, a simplified differentiated version for struggling readers, Spanish translations of both versions, and engaging activities including multiple-choice questions, writing prompts, and graphic organizers.

Sample passage and quiz from How Water Moves Inside Plants

Plants need water to live and grow, just like you need water to stay healthy. But how does water get from the soil all the way up to the leaves at the top of a tall plant? Plants have a special system inside them that solves this problem.

Inside every plant are tiny tubes that run from the roots, through the stem, and into the leaves. These tubes are like thin straws that carry water upward. When you drink through a straw, you pull the liquid up into your mouth. Plants work in a similar way. The tubes inside the plant pull water up from the soil where the roots are buried.

As water moves through these tubes, it carries important nutrients—materials from the soil that help the plant grow strong and healthy. The nutrients are like vitamins for plants. Without these tubes, water and nutrients could not reach the leaves, flowers, or fruits.

The tubes also help the plant stay firm and stand upright. When the tubes are full of water, the plant stands tall. When a plant does not get enough water, the tubes become empty, and the plant wilts or droops.

This transport system works all day and night, moving water from the roots to every part of the plant. It is one of the most important jobs happening inside a plant, even though we cannot see it from the outside.

Interesting Fact: A large tree can pull up more than 100 gallons of water from the soil in just one day! That's enough water to fill a bathtub.
