Lab Station #__________ |
Name___________________________ |
| Directions: | Use the program on Rocks and Minerals to answer the questions below. After beginning the program, select SEDIMENTARY ROCKS from the Main Menu. Answer the questions as carefully as possible. Remember, when you are finished, it will be assumed that you understand the material that was covered in the program. If you have questions during the program, make sure you ask your teacher! |
