ROCK AND MINERAL “BINGO”: APPLYING AND ASSESSING STUDENT ROCK AND MINERAL KNOWLEDGE AND IDENTIFICATION SKILLS
The Bingo cards are composed of 9 squares (questions) each. A total of 8 groups of questions have been developed to encompass introductory through more advanced levels. The question sets developed so far are: (a) General distinction between rocks and minerals; (b) Igneous, sedimentary and metamorphic rocks; (c) Mineral luster; (d) Mineral fracture and cleavage; (e) Mineral crystal form; (f) Mineral chemistry; (g) General mineralogy; (h) Geologic Context.
Each square on the card is numbered (1-9). The same card is used for each group of questions. The questions are written on a separate set of small question cards that are color-coded (according to question set) and numbered. These cards are pulled out of the bag' by the caller, and a copy of the question is posted for all to see. The players need to choose the sample from their collection that best fits the question or description given by the caller. The questions are set up so that some samples fit more than one answer, which requires the students to review their choices. The first person or group to win presents their board and samples for the class to examine.
This exercise could be adapted for any collection and any level of learning, as well as for any particular collection or suite of samples. Soils and local rock sequences could also be incorporated.
