Sedimentary Rocks

Sedimentary Rocks introduces students to a more in-depth look at this type of rock. Students will discover that there are many kinds of rock that fall into the sedimentary rock category. They will learn specific characteristics of several of these rocks. They will learn about limestone, dolomites, conglomerates, and more. There are many other kinds of sedimentary rocks, but this lesson will just focus on seven.

There are several different ideas in the “Options for Lesson” section that you may want to use in your lesson. For instance, you could gather some sedimentary rocks and have students guess the type of rock. You could also invite a geologist to come talk to the class about sedimentary rocks.


Sedimentary Rocks dives deeper into this type of rock and how it forms during the rock cycle. Students will learn which rocks fall into this category. They will see many examples and learn about their traits. By the end of the lesson, students will be able to identify sedimentary rocks easily. They may even be able to name some.

What Sedimentary Rocks includes

There are four detailed pages of content in this lesson. First, the lesson reminds students what the three main types of rocks are. Each type of rock has distinct traits and properties. All the rocks on Earth fall into one of these kinds of rock. Students will learn what sediment is and what it includes. Sediment means pieces of rock, sand, dead animals, plants, and other matter. If a rock is sedimentary, that means it could have all these different things in it.

Next, the lesson describes several kinds of sedimentary rocks. Some examples include shale, sandstone, limestone, iron ore, and coal. The lesson provides several details and traits for each of the rocks it presents. There are many more rocks of this kind, but students will learn about just seven types in this lesson.


Students must create an acrostic using the letters of the word “sedimentary” for the activity portion. First they will think of a word for each letter and put it on a poster board. Next, they will add color and images to the poster as well. They can either draw the pictures or find them online or in other resources. Tell them to be creative!


The practice worksheet provides a word bank of vocabulary words and a list of 15 statements. Students must fill in the blanks with the correct term based on the lesson. Then they have to answer two more questions at the bottom of the page.


For the homework assignment, students must match statements to the rock they describe. The options are the seven kinds of rock that they learned about during the lesson. There are 21 total statements. Students will use each type of rock more than once.
