Physical Properties: Something that I can see/feel/measure

Matter: Anything that has mass and takes up space.

Color

Conductivity: Allows heat and electricity to flow through it.

Density: Amount of matter packed into an object. Sink or float Density = mass/volume

Freezing Point: the point at which a liquid becomes a solid. 0◦C for water

Boiling Point: the point at which a liquid becomes a gas. Water Vapor (Gas) 100◦C for water Liquid water

Solubility: the ability to dissolve Salt into Water

Texture: how something feels when I move my hand across the surface. Tack = Sharp Log = rough Table top = smooth

Mass: amount of matter in an object Triple beam balance measures mass

Magnetic/Non-magnetic: attraction to a magnet

Melting point: the point at which a solid becomes a liquid.

Volume: How much space it takes up Volume of a solid is calculated by L X W X H Water displacement

Shape

We can also add…

Length Centimeters (cm) Inches (in)

Smell (odor)

Malleability: ability for metal to bend

Hardness: Moh’s Scale measures the hardness of minerals Quartz has a hardness of 7.

Streak: Residue from a mineral. A streak plate is used to find the true color.

Evaporating: A liquid turning into a gas.

Buoyancy: The ability to float Sink = more dense than water Float = less dense than water

Ability to insulate: stops the flow of heat or electricity. Fabric Oven Mitt Rubber tires Styrofoam cup

Chemical Properties of Matter: characteristic of a substance that is observed during a reaction

Flammability: the ability to burn.

Corrosiveness: Acid eating away at metal

Rusting: Iron reacts with oxygen and creates Iron Oxide (rust)

pH: measures acidity or alkalinity of a solution.

Rotting: decaying and creating new things Moldy bread – being broken down by the mold.

We can also add…

Ability to tarnish: silver reacts with oxygen. Not tarnished Tarnished

Burning or combustion of fossil fuels: burns because it is a new product OIL

Digestion: Energy from proteins and sugars are broken down into something new.

Photosynthesis: changing water, carbon dioxide, and light energy into glucose (sugar)

Evidence of a Chemical Change

Production of a Gas

Production of a Precipitate: when two liquids are combined and a solid is formed.

Color Change Sliced apples change color because they react with oxygen.

Change in temperature Break and/or shake for temperature change.

A spark, light or an explosion
