  1. STC: Rocks and Minerals Lesson 6: Observing Minerals: How Are They the Same and Different? • Enduring Understandings: • Each mineral is composed of only one substance, and that substance is the same in all samples of the mineral. • Minerals differ in color, texture, smell, luster, transparency, hardness, shape, and reaction to magnets.

  2. Think and Wonder How do minerals feel? Do any of them smell? In this lesson, you’ll explore your minerals with your senses. Then you will begin to record your observations in a special way. o

  3. Lesson 6: Observing Minerals: How Are They the Same and Different? Observing Your Minerals: From Lesson 5: How were the minerals you examined different from each other? How were the minerals similar? Today: Remember to use all your senses except TASTE! o

  4. Lesson 6: Observing Minerals: How Are They the Same and Different? Each pair of students needs: • Two hand lens • One set of minerals in an egg carton • One cardboard tray • Your crayons or colored pencils • One pair of disposable gloves o

  5. Lesson 6: Observing Minerals: How Are They the Same and Different? Explore! Remember to use your senses---except taste! o

  6. Sort your samples into groups according to a property of your choice. What property did you use? o

  7. Link to LRB Mineral Profile Sheets In your Laboratory Record Book: • Write the letters A to L after the word “Mineral” in the first box on each sheet. These match the letters of your egg carton. • Glue these into your LRB—one page per sheet. Do NOT glue them back to back! • Today we will only use the following boxes: • Mineral • Feel • Smell

  8. Mineral A • What does it LOOK like? Use your colored pencils or crayons to draw mineral A. 2. Record what mineral ‘A’ SMELLS like. 3. Record what mineral ‘A’ FEELS like. 4. Repeat for minerals B – L.

  12. Sulfur Have you ever smelled a rotten egg? When sulfur burns, it smells just like a rotten egg. In fact, rotten eggs have that smell because eggs contain sulfur! We need minerals such as sulfur in our food. It helps change food into energy and helps bones grow. When you eat eggs, onions, or cabbage, you are taking in sulfur. Where else do you think you might have smelled sulfur? When you watch fireworks on the Fourth of July, what do you think you are smelling? It’s sulfur!

  13. Sulfur also is used for making gunpowder, fertilizers, dynamite, and match heads. It’s an important ingredient in many medicines. Did you know that sulfur was used during the Civil War and World War I to prevent wound infections? Sulfur is found in many places. You can find sulfur crystals in some of the igneous rocks that form when volcanoes erupt. Sulfur is also found in limestone. Which of your minerals do you think is sulfur?
