Tennessee Academic Standards for Science
- 4.ESS2.1: Collect and analyze data from observations to provide evidence that rocks, soils, and sediments are broken into smaller pieces through mechanical weathering (frost wedging, abrasion, tree root wedging) and are transported by water, ice, wind, gravity, and vegetation.
- 4.ETS2.2: Determine the effectiveness of multiple solutions to a design problem given the criteria and the constraints.
