ASSESSMENT

1.
SOLIDS
• Solids are one state of matter.
• Solid materials have properties that separate them from other states of matter.
• Solids can be sorted by their properties.
• Solid materials have distinct uses, based on their properties.

• FOSS Science Resources: Solids and Liquids, “Everything Matters”
• Science Notebook: Students draw and write about solids. They draw and label their tower constructions.

Preassessment (optional)

Teacher Observation/Notebook Sheet
• Identifies properties of solid objects and sorts objects based on a property.
• Compares different solids.
• Identifies properties of a solid used for specific purposes in construction.


2.
LIQUIDS
• Liquids are one state of matter.
• Liquids have many properties.
• Liquids pour and flow.
• Liquids take the shape of their container.
• The surface of liquid is level with respect to the ground.

• FOSS Science Resources: Solids and Liquids, “Solids and Liquids”
• Science Notebook: Students draw and write about liquids and their properties. They use prepared sheets to record observations and respond to writing prompts. They make a bar graph indicating the number of vials of water it takes to fill four different containers.

Teacher Observation/Notebook Sheet
• Describes observations.
• Uses new vocabulary accurately.
• Draws liquids taking the shape of their container.
• Observes that the liquid surface remains level as the bottle tips.


3.
BITS AND PIECES
• Solid materials come in all sizes and shapes.
• Particles of solid materials can pour like liquids, but maintain their shape.
• Solid materials can support denser materials on their surface.
• Mixtures of solid particles can be separated with a screen.

• Science Notebook: Students draw and write about small solids and their properties. They record which screen is used to separate each material.

Teacher Observation/Notebook Sheet
• Compares properties of solids and liquids.
• Chooses screens of appropriate size to separate solids.


4.
SOLIDS AND LIQUIDS WITH WATER
• Some solids change when mixed with water; others do not.
• Some solids dissolve in water; evaporation leaves the solid behind.
• Some liquids mix with water; other liquids form a layer above or below water.
• Heating and cooling solids and liquids can change them from one state to another.
• FOSS Science Resources: Solids and Liquids, “Mix It Up!” and “Solids to Liquids and Back Again”
• Science Notebook: Students record the results of mixing solids and liquids with water. They make a bar graph of the results.

Teacher Observation/Notebook Sheet
• Accurately records observations.
• Supports opinions with evidence.
