Chemical and Mechanical Weathering of Rock— Student Laboratory Kit
In this wide-ranging laboratory kit, students experiment and observe how mechanical weathering, geological changes, glacial changes, ice expansion, chemical weather- ing, oxidation and organic processes affect rock specimens. Students observe which rocks are most affected and identify the chemicals and weathering processes with the greatest impact. Includes eight lab activities. Complete for 30 students working in pairs.

Common Uses of Rocks and Minerals—Student Laboratory Kit
Many items we use every day are mined from the Earth, including limestone in build- ing homes, feldspar in soaps and fluorite
in toothpaste. Students will perform 10 hands-on activities to determine the prop- erties of various rocks and minerals and identify their common uses. An excellent introduction to the common uses and prop- erties of rocks and minerals! Complete for 30 students working in pairs.

Clever Catch® Rocks
Learning about rocks couldn’t be more fun! Colorful, soft 24" inflatable vinyl ball provides an excellent way for students to improve their knowledge of rocks. Here
is how you play—the teacher tosses the ball to a student. The student answers the question found under his left thumb and then tosses the ball to another classmate. The next question is answered in the same manner and the game continues. A great interactive classroom activity! Contains more than 100 questions about differ-
ent types of rocks and how rocks form. Includes game-play directions and answer sheet.
