SmartBoard Lesson: Rock Cycle

Identify Rocks Game

Interactive BBC Bitesize Lesson explains characteristics of rocks, uses of rocks, and soils.

Rock Cycle Interactive (includes online test)

Identify the three major classes of rocks.
By looking at photos of real rocks, students will identify the typical characteristics of the three main types of rocks: sedimentary, metamorphic, and igneous. Students will also view animations to learn about the way each of these rock types is formed.
Understand the processes that cause rocks to change.
There are five major processes that can turn a rock from one type into another. Using animations and interactive drag-and-drop features, students will learn about these processes and the effects they have on rocks.
Conceptualize the recurring series of changes undergone by rocks.
Rocks are constantly — but very slowly — changing from one type to another all the time. The changes happen over and over again in a repeating cycle. Students will use an interactive diagram to learn about the rock cycle and what it can tell us about the rocks in our earth.
