Water Cycle

Overview

This lesson is Lesson 3 of 10 in the unit “Explorers of Systems,” focusing on Earth’s water cycle. Both students study the same core idea—how water moves and changes—then represent it at their levels.

Learning intentions

• Students will be able to name the main stages of the water cycle (evaporation, condensation, precipitation, collection).
• Students will be able to describe how water changes state and moves through Earth systems.
• Students will be able to communicate their understanding using a labeled diagram (Year 1) or a short researched report with evidence (Year 5).
• Students will be able to follow shared classroom routines for reading informational text and using evidence in explanations.

Success criteria

• I can correctly match water cycle stage words to a simple diagram (Year 1).
• I can explain the water cycle stages in order using sentences and correct sequence words (both, with support for Year 1).
• I can create a clear report with a main idea, key facts, and a concluding statement (Year 5).
• I can use text evidence (quoted words or paraphrased facts) to support at least one claim (Year 5).

Curriculum links

• Writing informational text: introduce a topic, use facts, and provide closure.
• Speaking and listening: present information clearly in an organized way.
• Reading informational text: identify the main idea and supporting details.
• Science and engineering practice: develop and use models to represent systems.

Lesson structure (240 minutes)

1. 10 min — Welcome + unit connection Briefly review what a “system” means in this unit (a set of parts that work together). Name today’s focus: water on Earth moving through stages.

2. 40 min — Read-aloud + stage pictures (shared theme) Use short, teacher-provided informational passages or printed pages about the water cycle. Pause to ask: “What is happening to the water here?” Students point to the stage that matches the description.

3. 55 min — Year 1: build a simple water-cycle diagram Student creates a circle/loop diagram with four labeled stages: evaporation, condensation, precipitation, and collection. Teacher models sentence stems for labeling, such as “Water warms and becomes water vapor” and “Clouds form when vapor cools.” Emphasis: correct order and readable labels.

4. 55 min — Year 5: research and evidence gathering Student reads a longer age-appropriate source (school library book pages or curated handouts). Student highlights or underlines key details about global significance (weather patterns, freshwater availability, and why the cycle matters). Teacher provides an organizer: main idea, 3 supporting facts, and 1 sentence explaining the system connection.

5. 20 min — Oral share + sequence check Both students do a quick “stage walkthrough” using the diagram. Year 1 uses a teacher checklist for order and label accuracy. Year 5 states: main claim + one piece of evidence + how it connects to the system.

6. 30 min — Write and revise (targeted outputs) Year 1: completes 3–4 simple sentences under their diagram using the stage words and sequence words (first/next/then/finally). Year 5: writes a one-page report: introduction (topic sentence), body (facts with evidence), and conclusion (why the cycle is important).

7. 10 min — Reflection + exit question Students answer a single prompt: “Which stage changes water from one form to another, and what changes?” Year 1 may answer with a single sentence; Year 5 answers with 2–3 sentences and references a detail from the text.

Resources

• Printed water-cycle informational passages (short for Year 1, longer for Year 5)
• Stage word cards: evaporation, condensation, precipitation, collection
• Water-cycle diagram template (loop/circle with boxes and arrows)
• Markers/colored pencils, glue, scissors
• Highlighter or colored pens for evidence marking (Year 5)
• Writing sentence stems (Year 1) and report organizer (Year 5)
• Optional props: clear cup with warm water (demonstration) and observation notes
• Teacher-made checklist for stages and labeling accuracy
• Timer for timed steps (flexible pacing allowed)

Assessment

• Diagram accuracy: Year 1 stage labels correctly placed and in order.
• Evidence use: Year 5 includes at least one supporting detail from the text and explains its relevance.
• Written communication: both students use sequence words appropriately; Year 5 includes a clear topic sentence and closing statement.

Differentiation

• For Year 1 (support): Provide pre-written label options and allow pointing-to-answer for the first draft of sentences. Use one stage at a time with teacher verification.
• For Year 5 (support): Provide a model paragraph and a sentence frame for each body fact: “One key fact is… This matters because…”
• For EAL/SEN: Use visuals first (stage pictures) and then add vocabulary. Accept oral responses and use word banks. Keep writing targets small but clear.
• For advanced learners (extension within today’s plan): Year 1 adds one extra detail sentence (example: “Condensation makes clouds”). Year 5 adds a short “cause-effect” sentence linking the cycle to a specific real-world event (example: rainfall after evaporation).

Extension (optional)

• If time remains tomorrow’s start: students create a 3–5 question “Water Cycle Quiz” for each other—Year 1 uses picture/word choices; Year 5 writes short-answer questions with an evidence prompt.
