Students will enjoy identifying the 14 rock specimens included in this kit. Glass plates, magnets, white and black streak plates, and vinegar aid in the identification of the rock specimens. Kit also includes a Teacher's Guide, video, class set of rock flow charts, and an assortment of books/activity guides. **Note** When completing the rock identification, please remember to perform the vinegar test after making a small scratch on the rock sample; place the vinegar drop directly where the rock was scratched.
