Water Cycle Start

Overview

Students explore how water moves around Earth through the water cycle. They focus on evaporation, condensation, precipitation, and collection, then create a labelled visual diagram to show the stages and what they mean.

Learning intentions

• WALT explain the main stages of the water cycle: evaporation, condensation, precipitation, and collection.
• WALT describe how the Sun and temperature changes affect water’s state (liquid to gas and back).
• WALT create a clear visual model that shows the sequence and purpose of each stage.

Success criteria

• I can name and order the key stages of the water cycle.
• I can match each stage to a simple description (what is happening to the water).
• I can use arrows and labels in a diagram to show the cycle clearly.
• I can explain why the water cycle matters for living things and the environment.

Curriculum links

• Scientific literacy: understanding basic physical processes and representing ideas using drawings and models.
• Nature of Science: using evidence from observations/activities to support explanations.
• Curriculum goal: building knowledge of Earth systems and how they change over time.
• Key competencies: thinking (sequencing and modelling), communicating (diagram labels and explanations), participating and contributing (group work).

Lesson structure (60 minutes)

1. 5 minutes – Hook and question

• Show a short teacher demonstration: a warm plate/bowl with warm water (or a picture sequence) to prompt discussion about “where the water goes.”
• Students turn-and-talk: “What happens to water when it heats up and then cools down?”

2. 10 minutes – Mini-lesson: stages and science ideas

• Teach the water cycle using simple language and visuals.
• Emphasise: evaporation happens when Sun heat warms water; condensation forms when water vapour cools into tiny droplets; precipitation is water falling (rain/snow/hail); collection is water gathering in rivers, lakes, oceans, and groundwater.

3. 10 minutes – Group activity: order cards

• Give each group a set of stage cards (evaporation, condensation, precipitation, collection) plus matching description cards and “Sun/temperature” prompts.
• Students physically arrange the cycle in order and justify their order using sentence starters (e.g., “First…, because…”).

4. 15 minutes – Build visual diagrams (individual)

• Students create a visual water-cycle diagram in their books or on prepared paper.
• Requirements: a closed loop or clear cycle, arrows, labels for all four stages, and at least one sentence at the bottom explaining what drives the cycle.

5. 10 minutes – Gallery walk: peer feedback

• Students rotate in pairs to view two other diagrams.
• They give “Glow and Grow” feedback: one thing that is clear and one suggestion (e.g., add an arrow direction, improve a label, ensure the order is correct).

6. 7 minutes – Whole-class check for understanding

• Use quick teacher questioning: “What changes first—temperature or state?” “Where does the water end up?” “What stage causes droplets to form?”
• Students respond with mini whiteboards/quick hand signals (or short verbal answers).

7. 3 minutes – Exit reflection

• Students complete an exit ticket: draw one arrow in their diagram and write one sentence describing what happens at that stage.

Resources

• Stage and description cards (evaporation, condensation, precipitation, collection, Sun/heat/cooling prompts)
• Visual cue cards or poster of the water cycle stages
• Student diagram templates (optional) with space for labels and arrows
• Markers/coloured pencils and rulers
• Mini whiteboards or scrap paper for quick responses
• Paper towels and safe warm-water materials for teacher demonstration (ensure safety procedures)
• Access to a classroom wall display for “Gallery walk” pin-up
• Sentence starters on the board for group discussion and explanations

Assessment

• Formative assessment through observation during card sequencing and the teacher’s questioning.
• Diagram assessment using the success criteria: correct stages, clear sequence, labels, and a short explanation.
• Exit ticket to confirm understanding of at least one stage and its driving idea (heat/cooling).

Differentiation

• Support: provide a partially completed diagram template with arrow outlines and word bank labels; offer sentence starters for explanations.
• Support: smaller group roles (card reader, arranger, label writer) to ensure all students contribute.
• Extension: challenge students to add a “living things” or “weather” connection (e.g., how precipitation affects plants and animals) and include one example type of precipitation.
• EAL/SEN: allow oral responses or sentence frames; use picture supports for each stage; pre-teach key words through visuals rather than definitions alone.
