After completing your unit on rocks/minerals, this is an engaging and fun activity for your students to play with. You can set this up as a competition or not. Your students are given a scenario of a make believe character, "Miss Marble" and she has been kidnapped by Silly Slate and Tacky Talc. They are given clues of her whereabouts based upon rock/mineral terms you have studied. As they solve the clues, they are able to find the location of Miss Marble.
