Scientific Investigation of Soil

At Half Day School, fourth-graders are learning about what makes up soil in different regions, how physical and chemical weathering of rock takes place, and how erosion and deposition lead to new land formations. They are also learning about how fossil evidence can show us how the earth can change drastically over time.

This study of the earth systems is part of a fall unit on soils and weathering that students study in science. During science time, students are expected to demonstrate grade-appropriate proficiency in asking questions, developing and using models, planning and carrying out investigations, analyzing and interpreting data, constructing explanations and designing solutions, engaging in argument from evidence, and obtaining, evaluating, and communicating information. Students are expected to use these practices to demonstrate an understanding of the core ideas.

The study of soil and weathering is part of the Next Generation Science Standards (NGSS). Standards set the expectations for what students should know and be able to do. The NGSS were developed by states to improve science education for all students.
