Rock Type Comparison

This worksheet supports students in Grades 4, 5, and 6 as they build a clear understanding of igneous and sedimentary rocks through classification, close reading, and comparative reasoning. By analyzing descriptive statements about formation, fossils, layering, and mineral content, learners sort information accurately and then synthesize their findings to explain similarities and differences using scientific vocabulary and evidence.

Learning Goals

• Comparing Rock Types (Grades 4-6) – Distinguish between igneous and sedimentary rocks using formation clues and physical characteristics.
• Classification & Sorting Skills – Analyze descriptions and sort them into Igneous, Sedimentary, or Both categories.
• Earth Materials Understanding – Explore how processes such as cooling, compaction, and layering shape different rock types.
• Comparative Reasoning – Identify and explain similarities and differences using organized chart evidence.

Instructional Benefits

• Teacher-Created Resource – Designed by educators to align with upper elementary Earth science standards.
• Structured Chart Format – Supports organization, clarity, and visual comparison.
• Critical Thinking Focused – Requires reasoning based on descriptive clues rather than memorization.
• Flexible Use – Ideal for classwork, homework, review lessons, science notebooks, or assessment.

This printable worksheet helps students strengthen scientific classification, comparison skills, and understanding of Earth materials by guiding them through careful analysis and synthesis of information. Learners practice interpreting scientific text, organizing details logically, and using precise vocabulary to explain rock characteristics. Well suited for both classroom and homeschool settings, this no-prep activity supports deeper learning through structured comparison and evidence-based reasoning.
