Assess students' understanding of the simple water cycle for Pre-K–Grade 2: the Sun's role in heating water (evaporation), how water vapor forms clouds (condensation), and how clouds release rain (precipitation). Items should include sequencing the steps, identifying causes (why water evaporates), labeling simple pictures/diagrams, and one short application question predicting what happens if the Sun or clouds change. Focus on conceptual understanding and age-appropriate explanations.
