This 2nd Grade Erosion Lab is aligned to the NGSS Performance Standard 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly. Students work together to create a model to show how erosion changes the land.
This 3-page download consists of a cover page overview of the lab, an observation form for students and an assessment.
This is just one exploration from a larger unit that is working toward the NGSS standard. In my classroom, students used the knowledge gained from this lab, their classroom text books and outside resources to complete the standard.
