  • Tell your students that there are three different kinds of rocks. The first type is called igneous. Igneous rocks are composed of melted rock that hardens and cools. A few examples include obsidian and pumice. Show your students a picture of each example.

  • Explain that the second type of rock is called sedimentary, and they're formed from material that is settled into layers. The layers are squeezed until they harden into rock. A few examples include limestone, breccia, and sandstone. Show your students a picture of each example.

  • Tell your students that the third type of rock is calledmetamorphic. These rocks are changed by heat and pressure. A few examples include slate and marble. Show your students a picture of each example.

Teacher ask students to take notes:


Teacher will show students the nearpod video:



Student Instructions

Students will work in pairs or groups to answer questions from the presentation.  

Student will move and sit with their team.

3 GUIDED PRACTICE: Identify Rocks lab activity

Demonstrate each type of rock using the examples below. If the hands-on materials aren't available, simply use each scenario as an analogy to help your students better understand the differences between the three kinds of rocks.

Get an ice tray. Fill it with water and put it in the freezer. After an hour, show your students that an igneous rock is like a cube of ice. It's originally melted, then hardens after being put in the freezer. It's cool when you take it out.

Give your students the example of an omelet for metamorphic rocks. Tell your students that the egg is mixed with various ingredients, and then cooked. The egg experiences heat and pressure from the flames of the stove, which enables it to turn into an omelet.

Display a picture of a layered cake to your class, and tell your students that this is similar to how sedimentary rock is formed. Tell them the various layers of the cake come together after baking in the oven.

Teacher will give students a handout.  


Teacher will have a rock in each station labeled with a letter of the alphabet.  

Teacher will divide students into partner/groups.

Teacher will instruct student on expectations and give them a time limit.

Student Instructions

Students will read handout aloud.

Student will get with their partner/group.

Students will work together to identify each rock in each station.  

Students will work together on pre-lab questions.

Students create a sandwich  using construction paper.

Students describe igneous and metamorphic rocks on the slices of bread and sedimentary in the middle.

4 INDEPENDENT PRACTICE: Personal Reading from book and a play quizizz

Teacher will introduce students to the following website

Teacher will first show students the walk through video.

Teacher then puts the code up for students to start the independent practice, which can be for a grade of the teacher chooses to.




Student Instructions

Students will first read about rocks in their books.  

Student each work on his/her own chromebook and play the game on quizizz

5 WRAP-UP: Sum up the lesson, by having kids do an exit ticket on formative.com

Teacher randomly calls on students to share what they learned today.


Teacher display on overhead formative results.

Teacher assigns students for homework to bring a rock to class.

Student Instructions

Students will each go online and answer the following:

3 things that we learned today in class.


6 Extended Activity

Activity: Exploring

Teacher instructs students to bring a rock to class the following day.  Teacher gives students a worksheet to research the rock that was brought to class. 

Student Instructions
