CMS fourth-graders learn about mechanical weathering Science experiment Click on headline for story with photo(s) By Calen McKinney Campbellsville Middle School fourth-grade science students are learning about how rocks break apart, and recently did an experiment to see it happen firsthand. Students are studying the term mechanical weathering, which is the processes that cause disintegration of exposed rock without changes in the rock's chemical composition. In Samantha Coomer's class, students were asked to perform an experiment to determine how ice can break rocks apart. Mechanical weathering from ice can take years, but, in their experiment, students saw the effects in just two class periods. To perform their experiment, students created a model of mechanical weathering by using balloons, plaster of Paris, milk cartons and water. Students were divided into two groups - those whose water was frozen and those whose water remained at room temperature. First, students' milk cartoons were filled with water and Plaster of Paris. Next, students took a balloon filled with water and pushed it into the milk cartoon. Those in the room temperature group set their cartons aside, and those in the frozen group put theirs in a freezer overnight. The following day, students observed what happened to their balloons, and saw how mechanical weathering works first-hand. Throughout the experiment, students answered questions about what they thought would happen to their balloons and more. This story was posted on 2016-09-21 05:44:56
