FOSS Third Edition Solids and Liquids

The Solids and Liquids Module provides opportunities for students to observe, describe properties and behaviors of solids and liquids, as well as engage in scientific and engineering practices. Students observe that matter exists in three fundamental states: solid, liquid, and gas.

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 different 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).
• Observe and describe changes when solids and liquids are heated and cooled.
