Grade 4 Rocks and Minerals Practice Test

Build Grade 4 Science skills with five 10-question practice tests on mineral properties, rock types, rock formation, the rock cycle, fossils, investigations, and Earth material uses.

Rocks and Minerals Practice Tests

These Grade 4 Science practice tests help students classify minerals and rocks and explain how Earth materials form and change. Students use properties such as hardness, luster, streak, layers, and texture to identify samples and connect rocks to the rock cycle.

Skills covered

  • Defining minerals and identifying mineral properties
  • Distinguishing igneous, sedimentary, and metamorphic rocks
  • Explaining melting, cooling, compaction, cementation, heat, and pressure
  • Connecting fossils and layers to sedimentary rocks
  • Planning fair tests and using evidence to classify samples
  • Understanding how people use and conserve rocks and minerals

How to use these practice tests

Use more than one property when identifying a mineral or rock. For rock types, ask how the material formed: cooling melted rock, compacted sediment, or changed existing rock under heat and pressure. Use observations and measured evidence to support conclusions.
