FOSS Module Summary

Module Summary – Pebbles, Sand, and Silt (3rd Ed.)

The Pebbles, Sand, and Silt Module provides experiences that heighten primary students' awareness, curiosity, and understanding of Earth's natural resources – rocks, soil, and water – and provides opportunities for students to engage in scientific and engineering practices. Students explore the natural world by using simple tools to observe and describe properties of earth materials. In this module, students will:

  • Observe and compare physical properties of rocks and soils, using various tools.
  • Rub rocks together and observe that they break into smaller pieces.
  • Use screens to separate and group river rocks by particle size, and investigate properties of pebbles, gravel, sand, silt, and clay particles.
  • Observe weather by using senses and simple tools.
  • Explore places where earth materials are naturally found and ways that earth materials are used.
  • Use sand to make sculptures and clay to make beads, jewelry, and bricks.
  • Find, collect, record, and compare samples of soil outside the classroom.
