In Science Class . . . Week of 12/5

This week in science, we acted like geologists and broke apart our fake rocks to see what "minerals" were inside. The students were able to identify several different ingredients, including red and green gravel, shells and some gray material. We then used water to see if we could separate the gray material. Key Questions:

• What is the difference between a rock and a mineral? (Minerals are the ingredients of rocks and are just one type of substance, while rocks are made of many types of minerals.)
• What types of "minerals" did you find in the "mock rock" Ms Jenkins made? (Most groups will find red and green gravel, shells, and gray material that we separated with water)
• What do geologists do? (They study rocks and make observations about the shape, size, texture, color, shininess, mass.)
• How are rocks and minerals used by humans? (We use them in various mixtures for roads, houses, jewelry, etc)
