Ores are rocks with enough of a useful mineral to mined.
They will engage in various scientific experiments, using science tools that will require measuring, observing, analyzing, and investigating to collect data to identify properties of rocks, minerals, and soil. The students will also use grade level books, the Internet and electronic resources to gather information about rocks, minerals, and soil. The students will be introduced to rocks by answering a rock riddle. A second grade student will then be paired with a third grade students to observe a rock of their own. They will then have to locate their particular rock based on the observations they made when the rocks are placed into a container.
