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