How did the lab activities help you answer the lesson question, "How are minerals and rocks classified?” What did you learn from conducting this lab?

Answer:

The lab activities showed that minerals can be classified by testing physical properties like hardness, streak, luster, and cleavage. I also learned that rocks are classified based on properties like grain size, mineral composition, and foliation, which provide clues about how the rocks were formed.
