FOSS Module Summary

Module Summary – Solids and Liquids (3rd Ed.)

The Solids and Liquids Module provides experiences that heighten primary students' awareness, curiosity, and understanding of the physical world and provides opportunities for young students to engage in scientific and engineering practices. Matter with which we interact exists in three fundamental states: solid, liquid, and gas. In this module, students will:

  • Investigate and sort objects based on their properties.
  • Observe, describe, and compare the properties and behaviors of solids and liquids. Record observations with pictures, numbers, and words.
  • Recognize the properties of solid materials that make them appropriate for tower construction; build towers.
  • Combine and separate solid materials of diff erent particle sizes using tools.
  • Observe, describe, and record what happens when solids and water are mixed and when liquids and water are mixed.
  • Use knowledge to conduct an investigation on an unknown material (toothpaste).
  • Use knowledge to conduct an investigation on an unknown material (toothpaste).
