The table below provides information about several mineral samples that were used during an investigation. mineral, color, streak, luster, hardness, apatite, pale, green, white, glassy, 5, halite, gray, white, glassy, 2.5, calcite, light, green, white, glassy, 3, feldspar, gray, white, glassy, 6,

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.
