Transformative Properties of Water Kit
Investigate the properties of water and how they affect Earth’s materials and processes. In this series of 3 investigations, students seek to understand how water can change rock. They determine how chemical weathering impacts different rock types by exposing rock samples to vinegar and observing changes in both mass and appearance. Then they model mechanical weathering through frost wedging, the movement of water over rocks, and measuring and observing changes in the rock materials.
While designed for a stand-alone earth science course, this series of activities could be incorporated into a high school chemistry course during a unit on properties of water.
Teacher prep, 115 minutes. Completing the activities, approximately 2 weeks (280 minutes).
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.
