Analyzing Diamond Data Activity #14
Key Concepts Minerals are crystals that form naturally on Earth. They have characteristic properties such as color, hardness, and a crystalline shape. Conclusions can be made by comparing experimental data to known properties.
Vocabulary Acrylic – word used to describe plastic. It is a man-made material that can be formed into many shapes and colors. Diamond = the hardest material. Diamonds are composed entirely of carbon atoms. Usually has an octahedron shape and comes in many colors. Fluorite – an inexpensive, abundant material found worldwide. Comes in a variety of colors.
