3 in-class hoursAssignments
1 hour per week. Students will collect samples, materials and other things to create a test kit of their own.Certificate of Completion
A game after class one and a game at the end of class 4 will assess the students comprehension and recall of the subject matter.Class Experience
US Grade 3 - 6
Class 1: How rocks and minerals are formed will be explored and the three main types of rock identified: Igneous, metamorphic and sedimentary. Students will learn how to identify these types of rock as a basis for later identifying minerals and gems. Knowledge will be assessed through use of a KWL chart and a review game at the end of the lesson. No homework for class 1. Class 2: Students will be guided through a demonstration using the MOHS scale of hardness. Students will learn what to collect to create a toolbox of their own. They will be given a handout out of the MOHS scale and instructions to put together their own kit. Homework assignment: to collect the materials on the list. Most are easily found in any household. Class 3: Students will discover other tests utilized to help identify the properties of various minerals. These will include use of UV light, and chemical tests. They will observe demonstrations of each. A discussion about the reactions and results will conclude the class. Homework Assignment: Collect a few rocks from the ground in your neighborhood to analyze at the last class meeting. add afew items to your testing kit. (Only common, non-toxic, household items will be included). Class 4: Students will test stones they have collected and analyze the results, using items in their test kits. The class will collaborate and discuss on the decisions to identify the rocks. We will play a game of Jeopardy to review the things we have learned in this class.

I have been collecting and researching crystals and gemstones for many years. I have an extensive collection of crystals and a deep fascination with learning how crystals have been used throughout history. My son hunts and polishes stones in his basement workshop so I am very familiar with the process of finding and bringing stones to their polished beauty. I love crystals and gemstones, both for their beauty and their versatility. Reviews
