Fun facts about rocks for kids

Learning about rocks can be fun, so make sure you share some of these fun facts with your students:

Did you know that the Earth’s oldest rocks are over 4 billion years old? That’s even older than dinosaurs!
Some rocks can actually float in water! Pumice, a type of volcanic rock, is so porous that it can float on the surface of water.
The largest known rock on Earth is Mount Augustus in Western Australia. It’s actually a rock formation that covers an area of about 1,900 square kilometers!
Have you ever heard of geodes? These are ordinary-looking rocks that can hide beautiful crystal formations inside. It’s like a hidden treasure waiting to be discovered!
Rocks can come in a wide range of colors. For example, the vibrant red color of the Grand Canyon rocks is caused by iron oxide, commonly known as rust.
Some rocks can glow in the dark! These rocks, called fluorescent rocks, contain special minerals that emit a colorful glow when exposed to ultraviolet light.
Meteorites are rocks that have fallen from space and landed on Earth. They can be remnants of asteroids or even fragments from other planets!
Rocks can change over time due to weathering and erosion. Just think about how rivers and waterfalls can shape rocks, creating unique formations like canyons and caves.
The famous Stonehenge in England is made up of massive rocks called megaliths, weighing up to 25 tons each. It’s still a mystery how people from ancient times moved and placed these gigantic stones!
Rocks play a crucial role in our everyday lives. They are used to build houses, roads, and even bridges. Without rocks, many of the structures we rely on wouldn’t exist!

Different types of rocks

Our first worksheet is designed to challenge young geologists with four intriguing questions.

Guided by illustrations, children will be tasked with identifying the type of rock, understanding how rocks are formed, discovering their natural habitats, and even exploring examples of rocks found in our world.

Through these thought-provoking questions, children will be encouraged to observe, think critically, and expand their understanding of the fascinating origins and diversity of rocks.

There is also the exact same worksheet but with a picture of a girl. Plus the answer sheet is included.

Igneous-rock

How are the rocks formed: Igneous rock forms when molten rock (magma or lava) cools and solidifies. Magma cools underground to form intrusive igneous rocks, while lava cools on the Earth’s surface to form extrusive igneous rocks. Cooling rate affects the rock’s texture.

Where are the rocks formed: Igneous rocks form in two main locations:

Intrusive Igneous Rocks: These form beneath the Earth’s surface from the slow cooling of magma, resulting in coarse-grained textures. Common sites are within continental crust or under oceanic islands.
Extrusive Igneous Rocks: These form on or near the Earth’s surface when lava cools rapidly, often resulting in fine-grained textures. This happens typically at or near volcanic regions, like along mid-ocean ridges, volcanic islands, or continental volcanoes.

Sedimentary rock

How are the rocks formed: Sedimentary rock forms through the deposition, compaction, and cementation of sediment. This sediment is derived from the weathering and erosion of pre-existing rocks, transported by water, wind, or ice, and deposited in layers over time.

Where are the rocks formed: They begin with the weathering of the exposed rock into small fragments. Through erosion, these fragments are removed from their source and transported by wind, water, or ice, to a new location. Once it settles the lowest layers become compacted so tightly that they form solid rock.

Metamorphic rock

How are the rocks formed: Metamorphic rock forms when existing rock is subjected to high temperatures, pressures, or chemically active fluids, altering its mineral structure without melting. This process, called metamorphism, occurs deep underground or in tectonic zones.

Where are the rocks formed: Metamorphic rocks form deep underground and at tectonic boundaries. These environments expose rocks to intense pressure and heat, transforming them through processes like recrystallization during mountain building or where tectonic plates collide.

Younger kids will love our preschool rock activities!

Sorting rocks worksheet

This engaging worksheet guides young geologists on a journey to categorize various rock samples into three distinct groups: igneous, sedimentary, or metamorphic rocks.

Igneous Rocks: Include rock samples like pumice, basalt, obsidian, granite, and diorite. These rocks form from the cooling of magma or lava.

Sedimentary Rocks: Include samples like sandstone, limestone, flint, and halite. These are formed by the accumulation and cementation of sediments.

Metamorphic Rocks: Include samples like quartzite, marble, and slate, which are formed under high pressure and temperature conditions that alter their original structure.

Activity objective:

Children will interact with these rock samples to observe and analyze their unique features and characteristics.

This hands-on experience will help them develop a keen eye for detail and enhance their ability to classify rocks based on their formation processes and geological changes.

Educational benefits:

Enhanced observational skills: Handling real rock samples allows children to notice subtle differences and similarities between the rocks.
Deepened geological understanding: By sorting these rocks, children will learn more about the geological processes that shape our planet, such as cooling, sedimentation, and metamorphism.

This worksheet is a practical tool for budding geologists to connect theoretical knowledge with real-world applications, making learning both fun and immersive.
