//__**Know the following vocabulary**__// Rock- Mineral Constants- variables that do not change in an experiment Dependent variable - factor being mesured in an experiment Independent variable - factor that changes in an experiment Hypothesis - an educated guess Earth science **Lava -** magma that reaches the earth's surface and comes out of a volcano **Magma** - molten rock below the earth's surface Igneous rock-Made from Lava or magma Metamorphic rock Sedimentary rock Sediments Large mineral crystals show that a rock cooled slowly allowing the crystals to form slowly and become large. Small crystals shows that a rock cooled quickly and mineral crystals are not seen with the naked eye. If you test more than one variable at a time you cannot conclude what variable had affect on the experiement. **Know how to read and understand pictures of crystal systems** **Know how to read and understand Mohs scale of hardness** **Know how to read and understand the rock cycle diagram** **Know the Scientific Methods, what they steps are and the order**
 * Be prepared to answer the following.** **Where does the rock cycle begin?** The Rock Cycle has no beginning or end. Matter is never created or destroyed. It just keeps changing into different types of rock by various processes.
 * Questions on mineral crystal size and what it tells you about the rock**
 * Questions about experiments and the testing of variables in the experiment.**


 * 1) State the Question or **problem**
 * 2) Gather information (**research)**
 * 3) Form a **hypothesis**
 * 4) Test your hypothesis (**experiment)**
 * 5)  **Analyze** your data
 * 6) Draw a **conclusion**
