Mineral Identification and Rock Classification Worksheets for Grade 6 Science develop students’ ability to identify minerals from physical properties and classify rocks by their composition, texture, and formation processes. Using a TEKS Earth and Space Science context, this resource connects mineral identification, the three major rock types, and the rock cycle to evidence about how rocks form and change.

Identify Minerals Using Observable Properties

Students work with important mineral identification properties including hardness, cleavage, color, luster, streak, and density. The reading explains how these characteristics describe minerals and why scientists consider several properties together when identifying an unknown specimen. Students also examine the difference between hardness and cleavage and apply these terms through selected-response and written questions.

Classify Rocks by Formation and Features

The resource moves from mineral properties to the classification of igneous, sedimentary, and metamorphic rocks. Students connect cooling rates with igneous rock grain size, examine how sediments become compacted and cemented, and explain how heat, pressure, or chemically active fluids can alter existing rocks without completely melting them. Sedimentary layers, grain size, mineral composition, and texture are used as evidence for interpreting a rock’s history. The resource also introduces contact metamorphism and uses Texas examples such as limestone, sandstone, granite, and metamorphic rocks.

Apply Rock Cycle Reasoning

Multiple-choice and true-or-false questions reinforce key ideas about mineral properties, rock formation, metamorphism, texture, composition, and the rock cycle. Short-answer questions ask students to explain why multiple mineral properties are useful, how grain size can reveal the formation of igneous rocks, and what sedimentary layers can indicate about past environments. Matching and a cloze passage provide additional opportunities to work with essential vocabulary and processes.

An extended-response task asks students to explain how texture and composition can be used to classify a rock and infer its formation, including all three major rock types and formation clues. This supports students in connecting individual observations with broader geological processes.

Ready-to-Use Teacher and Student Support

• ✔️ Student worksheet focused on mineral identification and rock classification
