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.

Identify properties of materials which make them useful.
Key concepts: Useful properties - unbreakable, water-proof, light-weight, conducts electricity (see PME-IV.1 e.4, electric circuits), conducts heat, attracted to a magnet, clear. See EG-V.1 e.4 (uses of earth materials).
Real-world contexts: Appropriate selection of materials for a particular use, such as waterproof raincoat, cotton or wool for clothing, glass for windows, metal pan to conduct heat, copper wire to conduct electricity.

Identify forms of energy associated with common phenomena.
Key concepts: Heat, light, sound, food energy, energy of motion, electricity (see PCM-IV.2 e.1 about heat, PWV-IV.4 e.1-4 about light and sound, PME-IV.1 e.4 about electricity, LEC-III.5 e.2 about energy from food).
Real-world contexts: Appropriate selection of energy and phenomena, such as appliances like a toaster or iron that use electricity, sun's heat to melt chocolate, water wheels, wind-up toys, warmth of sun on skin, windmills, music from guitar, simple electrical circuits with batteries, bulbs and bells.

Describe common physical changes in matter - size, shape; melting, freezing (K-2); dissolving, evaporating (3-5).
Key concepts: States of matter - solid, liquid, gas. Changes in size and shape - bending, tearing, breaking. Processes that cause changes of state: heating, cooling. See EH-V.2 e.1 (water in three states).
Real-world contexts: Changes in size or shape of familiar objects, such as making snowballs, breaking glass, crumbling cookies, making clay models, carving wood, breaking bones; changes in state of water or other substances, such as freezing of ice cream, or ponds, melting wax or steel, puddles drying up.

Prepare mixtures and separate them into their component parts.
Key concepts: Mixture, solution. Separation techniques - (K-2) filtration, using sieves, using magnets, floating vs. sinking; (3-5) dissolving soluble substances, evaporating.
Tools: Filter paper, funnels, magnets, sieves, beakers, solar stills.
Real-world contexts: Mixtures of various kinds - salt and pepper, iron filings and sand, sand and sugar, rocks and wood chips, sand and gravel, sugar or salt solutions.

Describe how water exists on earth in three states.
Key concepts: Liquid (K-2) - visible, flowing, melting, dew. Solid (K-2) - hard, visible, freezing, ice. Gas (3-5) - invisible, water vapor, moisture, evaporating. See PCM-IV.2 e.1.
Real-world contexts: Examples of water in each state, including dew, rain, snow, ice, evidence of moisture in the air, such as "fog" on cold bathroom mirrors; examples of melting, freezing, and evaporating.
