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 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.

What our Sedimentary Rocks lesson plan includes

Lesson Objectives and Overview: 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. This lesson is for students in 4th grade, 5th grade, and 6th grade.

Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand.

Options for Lesson

There are many suggestions in the “Options for Lesson” section that you could incorporate into the lesson if you have time or want to extend or adjust it. One suggestion is for students to write poems or stories about the formation of a sedimentary rock from the perspective of a piece of sediment. Another idea is to obtain different rocks and have students identify each one based on what they observe and what they learned. You could also plan a “Rock Week” during which you teach about all the types of rocks, including this lesson. One other option is to invite a geologist or rock collect to speak with the class and answer their questions.

Teacher Notes

The paragraph on this page provides a little more information on what to expect out of this lesson plan. It suggests teaching this lesson in conjunction with others that relate to rocks or geology in general. The blank lines on the page are for you to write down your thoughts as you prepare.


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.


The Sedimentary Rocks lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each of these helps solidify students’ grasp of the material and content they learned throughout the lesson. You can refer to the guidelines on the classroom procedure page, which outline when to hand out each worksheet.


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.

Worksheet Answer Keys

The last couple pages of the lesson plan document are answers keys for both the practice and homework worksheets. The correct responses are in red so that it is easy to compare them with students’ responses. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
