After School Spring 2017: Week 3

Weathering and Erosion

This week, Girlstart students (and future geologists!) reviewed physical weathering, chemical weathering, and erosion before putting different types of soils to the test!

Before beginning their activity, students worked together to review the difference between chemical and physical weathering. Tables volunteered their ideas, then STEM Crew leaders provided an antacid tablet for girls to observe. Students watched the tablet dissolve in a glass of water and create bubbles as an example of a chemical change. Crew leaders explained that the dissolved tablet had undergone a chemical change. Minerals in rocks can also dissolve - a common example of chemical weathering. On the other hand, physical weathering does not lead to a change in a rock’s chemical composition.

Exploring the Earth

During this week’s activities, Girlstart students learned about skills used by geomorphologists, who study geological processes and resulting landforms. Students brushed up on vocabulary that included “deposition,” “erosion,” and “weathering,” then got to work forming their own canyon models!
