The Rock Cycle & Minerals

MS-ESS2-1 • Develop a model to describe the cycling of Earth's materials

Rocks are constantly being made, broken down, and remade through a continuous cycle driven by heat from Earth's interior and energy from the sun. This page covers the three rock types, how they transform into one another, and how rocks differ from minerals — with a diagram, mini posters, and an interactive notebook organizer your students can build by hand.

How the Rock Cycle Works

Every rock on Earth is one of three types — igneous, sedimentary, or metamorphic — and every type can eventually become either of the other two. Follow the arrows below to see the paths rock material can take.

Rock Type Mini Posters

Each mini poster gives students a visual reference for identifying rock samples and remembering how each type forms. Print a set for student notebooks or display them as a classroom reference wall.

Igneous Rock

Forms when magma or lava cools and hardens into crystals. Can form slowly underground (large crystals) or quickly at the surface (small or no crystals).

Sedimentary Rock

Forms when layers of sediment are compressed and cemented together over time. Often contains visible layers and can preserve fossils.

Metamorphic Rock

Forms when existing rock is changed by intense heat and pressure without melting completely. Often has banded or foliated patterns.

Rock Cycle Interactive Notebook Organizer

This hands-on organizer lets students physically move wooden craft sticks labeled with rock cycle processes along a printed landscape, reinforcing the cyclical nature of rock formation in a way a worksheet alone cannot.

Print the landscape organizer and glue it into the interactive notebook.
Cut out the process labels (weathering, melting, heat & pressure, etc.) and attach them to wooden craft sticks.
Students slide each labeled stick into the correct pocket on the landscape to show the rock cycle in action.
When not in use, the sticks slide down into a pocket and the organizer folds flat — nothing falls out between classes.

Rocks vs. Minerals

Students often use "rock" and "mineral" interchangeably, but the two are scientifically distinct. This comparison organizer helps students sort the differences before moving on to mineral identification.

Rocks

Usually made up of more than one mineral
Do not have crystals
May be any shape
A mixture of colors
Irregular shapes
Classified based on how they are formed

Minerals

Made up of elements
Have a certain crystal structure
Usually have a definite shape
Usually have a definite color
Classified individually
Cannot be broken down into simpler substances

Mineral Mini Posters

Just like the rock posters above, these give students a quick visual reference for common minerals and their identifying characteristics — color, luster, hardness, and crystal structure.

Quartz

One of the most common minerals in Earth's crust, identifiable by its glassy luster and hexagonal crystal structure.

Mica

Known for splitting into thin, flexible sheets due to its layered crystal structure.

Feldspar

The most abundant mineral group in the crust, often pink or white with a distinct cleavage.
