Unit 1.3 Changes in the Earth's Surface
Students in grade 4 continue to conduct investigations and use observational data to describe how water moves rocks and soils, which should be taught at the drill-and-practice level of instruction. Students investigate local landforms to determine how wind, water, or ice have shaped and reshaped them. This is
a new concept, which must be taught at a developmental level. They continue to use models and begin to build their own models to simulate ways that wind and water shape and reshape land. Given information about properties of earth materials, students now determine the best building materials for a specific purpose, including which rock size will best prevent erosion. These concepts are new and need to be taught at the developmental level of instruction.
