Corinth : Types of Rocks

Types of Rocks

(Independent Learning)

Essential Question

How are rocks formed?

Learning Objective

By the end of this lesson, you will be able to...

identify the characteristics of three major types of rocks and explain the rock cycle.

Today's Lesson

Today's lesson is all about rocks. You will have a chance to reflect on what you already know about rocks, explore 3D models of rocks, learn about the three major rock types and the rock cycle, and test your knowledge in an interactive game.

Draw

Think about the coolest rock you have every seen and draw a picture of it below.

Corinth 3D Models

On the next few slides, you will review a 3D model of each major type of rock. You will first explore an igneous rock, then a sedimentary rock, and finally, a metamorphic rock. Be sure to describe each rock type. After exploring you will make a guess about the differences between these rock types based on your observations.

What were some similarities and differences between the rocks you explored? Remember, the first rock (granite) was igneous, the second (limestone) was a sedimentary rock, and the third (quartzite) was a metamorphic rock.

Rocks and the Rock Cycle

On the next slide, you will watch a video to learn about the three types of rocks and how they are formed. You will also learn how rocks are slowly but constantly changing in a process called the rock cycle. After the video, you will complete a few activities to check your understanding of the key ideas.

Rock Review

On the next slide, you will be prompted to a website to read the short text to review the key concepts you learned in the video. Be sure to read through the chart at the bottom of the page containing key characteristics to look for to help you identify different rock types. Then, you will play an interactive game to text your knowledge!
