2nd Grade Water on Earth worksheets

About this worksheet

This Grade 2 science worksheet gives focused practice with where water is found on Earth and how models represent it. The workbook reference treats science as evidence-based inquiry, so the questions ask students to read a small investigation, compare observations, and choose the claim that best fits the evidence. Second graders often know a science word from conversation but need support connecting it to a tested result, diagram, or class record. This page rotates through direct observation, cause-and-effect reasoning, model interpretation, and fair-test choices so the sheet does not become one repeated fact.

Support versions use familiar examples and short sentences. Standard and challenge versions add closer choices and require students to explain why an observation matters. A common slip is thinking water exists only in lakes or rain and forgetting oceans, rivers, ice, groundwater, and clouds. Encourage children to name the evidence first, then use that evidence to support the answer they choose.
