Description of the activity/assignment

In small groups, students make decisions on how to classify seven common objects as either minerals or non-minerals. The objects are: quartz, glass, wood, granite, copper, plastic, and ice. Students receive no prior instruction, and thus need to use their observations and their current conceptions of minerals in order to make and justify their classifications. After small groups have completed their classifications, a full-class discussion ensues, revealing differences among the groups, from which emerges a definition of "mineral".

Determining whether students have met the goals

Give students additional common objects and ask them to classify them as mineral or non-mineral, and justify their classification (to see if they are right/wrong for the right/wrong reasons). Examples could include: bone, coal, steel, oil, salt, sugar, paper, gold ring, etc.
