Group+3

William, Jazmin, Alyssa, Ben, Kelsey, Tyler
 * ==1. Group Members Here, you will type the first names of your group members.==

2. What is your purpose in creating your own rock classification system?
Any classification of rocks reflects a theory of how the world is, and works. If the theory changes then the classification changes too. It is important to have classifications that can help us come up with new theories on the world how it is changing

==3. You are now ready to begin characterizing your group's rocks. What are the characteristics of your rocks (that you can observe) that your need to consider in developing a classification system? List them below and make sure you include ALL the characteristics.== Color, Texture, Hardness, Cleavage, luster, Tracture...etc.

Together, as a group, predict which three characteristics will be most important in your classification system? Record your response here.
1.)Texture- Because you can tell what the diffrence is between a smoother rock and a rockier rock 2.)Luster- Because that could narrow it down between a more earthy rock and a more glassy looking rock 3.)Color- so you can narrow it down between the types of rocks with black color like Extrusive and the lighter rocks like Intrusive  = = =

=

Igneous Extrusive
8,6,15,2 ( the shiny peach and black one), 44

Igneous Intrusive
7, 5 ( red and purple looking one), 5(black one)

Sedimentary Clastic
22,2 (big one)

Sedimentary Chemical
Unknown Rock( red looking one)

Metamorphic Foliated
7

==Now, each member of your group should access the discussion board above and click on the third question "Where do we have problems?". After each of you has responded, read through the other responses and select two (from other groups) to reply to.==


 * 5. You are now ready to develop your classification system. You will do this on a large piece of paper in your group. You may want to start on a smaller sheet of paper with pencil first. Get started. You have 15 minutes.**


 * At the break time, each group member should respond to question four on the discussion board "where are we stuck?". After each of your responses, read the other's and respond to someone with either a similar problem as yours or one in which you think you can help.**


 * You should discuss what you found from the discussion board that might help your group proceed. Then, you have 20 minutes to finish your classification system on the large paper.**


 * 6. Now, your system is complete. You will trade with another group, as requested by your teacher. You will only trade your classifications system and NOT your basket of rocks. They will use their own basket of rocks to verify your system.

Upon getting their system and knowing what you know about your rocks, do you think your rocks will be classified correctly according to their system? Record your group's response below:

7. Now, evaluate their classification system with your rocks. Did their system accurately classify your rocks? Why or why not?

How was their system different from yours? Could theirs be fixed to work with yours? How? (be as specific as possible).

8. Individually, respond to the fifth question on the discussion board. This one will take some thought. Then, read and locate two others that interest you. Tell the authors what you think of their applications. Are they valid or not?** || ||   || Help · About · Blog · Terms · Privacy · [|**Support**] · [|**Upgrade**]Contributions to http://karlatucker.wikispaces.com are licensed under a [|Creative Commons Attribution Share-Alike 3.0 License].
