A scientist is observing mineral samples, however he is not sure of one of the samples. He proposes that it is a diamond. The scientist observes a clear color but knows that color alone is not a reliable property of identifying an unknown mineral. Which additional test should the scientist perform that would best confirm the mineral he is observing is a diamond?
The scientist should perform a magnetism test because diamonds have the ability to be attached to a magnet.
The scientist should perform a streak test because diamonds leave a colorless streak on a streak plate.
The scientist should perform a hardness test because diamonds have a hardness of 10 and is considered the hardest mineral.
The scientist should observe the luster because diamonds are known to have a shiny appearance.

A science student wants to start her own rock collection. She finds the following rocks in her backyard and records a description of each type of rock in the table. Using her detailed descriptions, classify each type of rock, and explain which evidence best supports the given answer.
Rock 1 is a sedimentary rock because small rock fragments underwent the processes of compaction and cementation. Rock 2 is a metamorphic rock because it has a glassy texture and formed from cooled lava. Rock 3 is an igneous rock because it is foliated and formed by extreme pressure.
