Lesson Plan - Get It!
If you have ever dreamed of becoming a "rock star," then look no farther! In this lesson, you will be introduced to the top three "rock stars" on the planet, and learn the secrets to their "rocking" success!
Meet the planet's three categories of rocks (you may consider them your rock stars for this lesson):
- Sedimentary rock (seh-deh-MEN-tri)
- Igneous rock (EG-knee-us)
- Metamorphic rock (met-ah-MORE-fick)
These rocks can be found all around us. Some may be buried deep beneath the Earth's surface, while others may be found on top of the highest mountain. Wherever they are, rocks have been around for a very long time. In fact, geologists (people who study rocks), consider rocks to be natural resources formed from heat, pressure, or a combination of both.
Take a closer look at the different rock classifications. You should know that each type of rock is different from another and was formed in a different way.
Introducing . . . Sedimentary Rock!
What are sedimentary rocks?
- Sedimentary rocks are formed when layers of sediment (i.e., particles of sand, shells, and pebbles) are compressed over time.
- Sedimentary rocks are generally soft and may crumble very easily.
- Most fossils are usually found in this type of rock.
- A closeup look at pieces of sedimentary rock will sometimes reveal bits of sand, pebbles, or stone.
- Limestone, sandstone, and chalk are types of sedimentary rocks.
Meet . . . Igneous Rock!
What are igneous rocks?
- Igneous rock is formed when lava produced by volcanoes cools and hardens.
- Magma can also cool deep beneath the Earth, forming igneous rocks.
- Granite and basalt are types of igneous rock.
Get to know . . . Metamorphic Rock!
What are metamorphic rocks?
- Metamorphic rocks are formed beneath Earth's surface.
- Intense heat and pressure beneath the Earth help form this type of rock
- Metamorphic rocks may often contain crystal particles and have ribbon-like layers.
- Marble, quartzite, and slate are types of metamorphic rocks.

Discuss the following questions. Record your responses to share with your instructor:
- Do you have a favorite rock type?
- What are some ways in which rocks are used today?
- What is the name given to people who study rocks?
When you are done, "rock on" to Got It? to learn more about rock classifications.
