=__**Abstract**__= The earth’s surface is made up of three main materials – rocks, minerals and soil. Without these materials people would not be able to live on the earth. Nearly everything in our world is made up of these three materials. This lesson will address the topic of rocks and there creation. At the end of this lesson students will be able to identify the three categories of rocks and label a diagram of the rock cycle.


 * __Materials__**
 * 1) Rock Samples.
 * 2) 30 Computers with internet access.
 * 3) 30 Fill in the blank Rock cycle handouts.
 * 4) Chart paper and markers.

Students will be able to define the following terms
 * __Definitions__**
 * 1) Igneous Rocks
 * 2) Sedimentary Rocks
 * 3) Metamorphic Rocks


 * __Goal:__** Students will be given a rock of mysterious origin and challenged to discover what type of rock they have; Igneous, Sedimentary or Metamorphic. They will need to use the internet to research the 3 different types of rocks in order to identify their rock sample, they will also be expected to create a diagram of the rock cycle. Once students have completed their research they will be asked to present their findings to the class by listing the characteristics of their rock sample which indicate its classification.

**__ Specific Learning Outcomes __**

1. Compare samples of various kinds of rocks 2. Identify similarities and differences between the sample rocks 3. Investigate the different properties of rocks. 4. Describe and classify a group of rocks based upon pre-determined properties 5. Label a diagram of the rock cycle. // C.1 - Students will access, use and communicate information from a variety of technologies //

|| ** Procedure **

||
 *  5 minutes

|| __ Introduction/Anticipatory Set: __ · Show the class a picture of the earth depicting the various layers. · Ask the class what the top layer is made of and write their answers on the board. · Ask the class what would happen if the top layer of the earth were missing · Prompt for responses to the above, stressing the importance of this layer for our survival

||
 * 10 minutes

|| __ Focus: __ // Types of Rocks // · Explain that there are 3 categories of rocks categorized according to: 1. Color 2. Luster 3. Texture 4. Hardness · Write the names of the three categories of rocks on the board and explain that their job will be to identify which categories their rock fits under by searching the web to find a definition for the 3 different types and labeling the diagram of the rock cycle using the information found. <span style="font-size: 10pt; color: rgb(128, 0, 0); font-family: Arial,Helvetica,sans-serif;"> ||

The teacher will fill in a class chart showing the characteristics of all the rocks studied. · Have students hand in their diagram of the rock cycle. · Using the class chart show how each category of rock really does display the same properties. · Ask if there are any questions. <span style="color: rgb(128, 0, 0);"> ·   <span style="color: rgb(128, 0, 0);">(Even in pairs, this presentational component will take significant time, especially if the goal is to reinforce the defintions of the three types of rocks.
