Original Prompt

mystery science prompt: In this lesson, students will explore how solid rock breaks apart into smaller pieces through a process called weathering (including root-wedging and ice-wedging). In the activity, Sugar Shake, students use sugar cubes as a model for rocks. They perform an experiment with this model to understand the process of weathering and how this process explains why rocks at the tops of mountains are jagged, while those at the bottom are rounded.

This resource provides an engaging introduction to the concept of weathering, explaining how solid rock is broken down into smaller pieces called sediments through various physical mechanisms. It covers key topics such as the definitions of weathering and erosion, the processes of ice-wedging and root-wedging, and includes an interactive experiment called the 'Sugar Shake Experiment' to model weathering. The document also delves into real-world examples of weathering processes, guided reflections to connect experimentation with natural phenomena, and a comic strip activity depicting the journey of a rock through the rock cycle. Essential for understanding the dynamic nature of Earth's landscape, this resource is structured to foster curiosity and critical thinking in students.
