Data Table/Observation Journal:
Create a data table with 9 rows, one for each rock sample. Label the columns with sample #, the rock’s name, color, grain size, texture, other observable physical properties, and the feature that was most important to identifying the rock. Be sure to include drawings and description of each of the rock samples as part of your observation journal.
Analysis: Make a bar graph that illustrates which attribute was used most/most successful in identifying the samples. Answer these questions:
1) Were there any samples that you found difficult to classify? Explain.
2) Which attributes were least useful for classification?
3) Classify each type of rock : igneous, sedimentary or metamorphic into its respective sub-groups and explain what allowed you to determine the sub group.
4) Give two reasons we are studying rocks.
Conclusion: Follow the lab RUBRIC.
