The Solids and Liquids Module provides experiences that heighten students’ awareness of the physical world. Matter with which we interact exists in three fundamental states: solid, liquid, and gas. In this module first graders have introductory experiences with two of these states, solid and liquid.
FOSS EXPECTS STUDENTS TO
- Develop curiosity and interest in the objects that make up their world.
- Investigate materials constructively during free exploration and in a guided discovery mode.
- Recognize differences between solids, liquids, and gases.
- Explore a number of liquids.
- Observe and describe the properties of solids and liquids.
- Sort materials according to properties.
- Combine and separate solids of different particle sizes.
- Observe and describe what happens when solids are mixed with water.
- Observe and describe what happens when other liquids are mixed with water.
- Observe and describe what happens when materials are mixed, cooled, and heated.
- Use information gathered to conduct an investigation on an unknown material and make new observations when discrepancies exist between descriptions.
- Draw pictures that portray features of objects.
- Record observations and data with pictures, numbers, and words.
- Organize observations on a bar graph.
