Background For Teachers:
Rocks are made up of two or more minerals. Rocks are divided into three classes, according to the way they are formed. The three classes are igneous, sedimentary, and metamorphic. Rocks can be identified and classified by texture, color, density, hardness, luster, magnetism, and cleavage.

Intended Learning Outcomes:
Make observations. Develop and use catagories. Understand science concepts. Use the language of science as a means of communicating.

Instructional Procedures:

Read the book Sylvester and the Magic Pebble. Discuss the various attributes of Sylvester's pebble.

Ask students to write what they know about rocks. What do they look like? What are their characteristics? Where do they come from? Encourage students to bring at least ten different rocks to class. Students are usually very eager to bring collections to school however you will need to have a collection of different types of rocks on hand for those students who forget to bring their rocks on the appointed day. Have the students get with a partner. Give an egg carton and magnifying glass to each pair. Have the students pool their rocks so each pair of students has 20 rocks. Give them rocks if necessary.

Working with their partner, have the students observe, discuss and write about the different characteristics of their rocks. Instruct students to make a list of the different characteristics of their collected rocks. Using the egg carting, have the pairs organize and classify their rocks into self selected categories (ie. large--small size, dark--light colored, dull--shinny luster, single--multi-colored, rough--smooth texture).

Have each pair discuss their findings with a neighboring pair. Have each student make an illustration of one of their rocks that shows two different characteristics. They should also write a description of one of their rocks. Encourage students to share their illustrations and written description with their partners. Instruct your students write questions about rocks. What are some other things they would like to know about rocks? What would they like to learn about the rocks they collected?

Extensions:
Make rock people or animals by glueing rocks together and painting them with tempra paints. Add eyes, spots, stripes or other features with permanent markers.

Assessment Plan:
Use the Rock Uses assessment rubric. Evaluate their written description for accuracy. Ask the students to describe and defend the method they used for sorting the rocks.
