The Water Cycle: An Introduction

Learning Objectives

• Students will be able to **identify and define** the four main stages of the water cycle (Evaporation, Condensation, Precipitation, Collection).
• Students will be able to **explain** the role of solar energy in driving the water cycle.
• Students will be able to **illustrate** the water cycle using a simple diagram.

Materials & Preparation

• Whiteboard or projector.
• Printed handout of the water cycle diagram (referenced in the adjacent column).
• Clear plastic container, water, and ice (for condensation demo).
• Student notebooks and colored pencils.

Lesson Procedure

1. 1. Engage (5 min):

   Ask students: "Where does the rain come from? What happens to the water after it rains?" Use a quick think-pair-share activity.

2. 2. Explore & Explain (25 min):

   Introduce the four stages using the projected diagram (see column on right). Define key vocabulary. Perform a quick demonstration of **condensation** using ice over hot water in a clear container.

3. 3. Elaborate (10 min):

   Guided practice: Students draw and label their own water cycle diagram in their notebooks, using color to highlight different stages.

4. 4. Evaluate (5 min):

   Quick exit ticket: "Define one stage of the water cycle and explain how the sun influences it."
