Weathering & Erosion

Last week the second graders became geologists, learning about fast and slow changes to the Earth’s surface. They began their exploration by learning about weathering, a natural process by which rocks and other minerals are broken down. The class used sugar cubes to conduct some experiments to help them gain a greater understanding of chemical weathering (changes the molecular structure) and physical weathering (which causes the minerals to crumble).

Next, the class discussed erosion, a geological process through which earthen materials are worn away and transported from one location to another by natural forces. The students then played a paper boulder game to help them better understand how erosion works.
