Students were given a mineral sample to identify, and they made several observations about the sample. The mineral was green and made a
white streak on a streak plate. It also had a glassy luster. The students were able to scratch the mineral with a sample of fluorite. Because of
this, they determined that the mineral had a hardness of less than 4. The students summarized this information in the table below.
