Classify common objects and substances according to observable attributes/properties.
Key concepts: Texture - rough, smooth. Flexibility - rigid, stiff, firm, flexible, strong. Hardness. Smell - pleasant, unpleasant. States of matter - solid, liquid, gas. Magnetic properties - attract, repel, push, pull. Size - larger, smaller (K-2); length, width, height (3-5). Sink, float. Color - common color words. Shape - circle, square, triangle, rectangle, oval. Weight - heavy, light, heavier, lighter. See PWV-IV.4 e.4 (shadows: objects that let light pass through or block light); PME-IV.1 e.2 (materials that conduct electricity); C-I.1 e.4 (use measuring devices).
Real-world contexts: Common objects, such as desks, coins, pencils, buildings, snowflakes; common substances, including - solids, such as copper, iron, wood, plastic, Styrofoam; liquids, such as water, alcohol, milk, juice; gases such as air, helium, water vapor.

Demonstrate ways to conserve natural resources and reduce pollution through reduction, reuse, and recycling of manufactured materials.
Key concepts: Materials that can be recycled - paper, metal, glass, plastic. Conservation and anti-pollution activities - reduce, reuse, recycle.
Real-world contexts: Collections of recyclable materials, plans for recycling at home and school, composting, ways of reusing or reducing the use of paper.
