2-PS1-1
The standard
Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
Next Generation Science Standards
What this standard means
Students need to plan a simple test, observe materials closely, and sort them by properties they can see or feel. They should use words like rough, smooth, hard, soft, bendy, stiff, clear, dull, shiny, or colored. They also need to notice patterns across different objects.
Mastery looks like making careful observations, using the same test on each material, and explaining why items belong in a group. Students often get stuck naming objects instead of properties, like “spoon” instead of “shiny” or “hard.” They may also sort by use, not by what the material is like.
Ways to teach it
- Give pairs fabric, foil, cardboard, plastic, and wood samples to test for texture, hardness, flexibility, and shine, then sort on a mat.
- Ask students to write: Which two materials are most alike, and what observations prove it?
- Show three mystery material cards and have students circle two properties that describe each one.
- Bring in a lunchbox item and discuss why its material works well for holding, bending, or protecting something.
