1. Read p. 353 of Foundations of physical science by Tom Hsu
Find and discuss the definition “change in physical property” Write this definition in your own words.
List as many physical properties as you can. Use your book, check the index read chapter and section headings.
As a team, define what a physical property is.

2. Physical Property
A physical property is one that is displayed without any change in composition. (Intensive or Extensive)
A characteristic that describes a property that is “owned” by a piece of matter and can be detected by our senses without changing how the matter is arranged
For example, you can observe the color of hair or taste the rainbow if you eat skittles without changing the hair or the candy.

3. Intensive properties: A physical property that will be the same regardless of the amount of matter
Brittleness: Tendency to shatter
State (solid, liquid, gas)
Condensation / Vaporization (boiling) point
Freezing / Melting point
Viscosity: resistance to flow
Miscibility: whether matter will combine to form a solution
Albedo: how much energy is reflected back compared to how much energy is absorbed.
Solubility: how much one substance can be dissolved by another substance.
Thermal conductivity: how heat flows through matter
specific heat: how much energy it takes to change the amount of heat something can hold
magnetism
density: m/v
color: The pigment or shade 
conductivity: How electricity flows through the substance
malleability: how much a substance can be flattened without breaking.
luster: how shiny the substance looks 
Hardness: Mohs scale resistance to scratching
Elasticity: How much something can stretch and return to it’s original shape before it breaks
Tensile Strength: how much the matter can be pulled before breaking
Buoyancy: related to density of a fluid-how much push back when pushed on.
Texture: How rough or smooth something feels

4. Extensive Properties
A physical property that will change if the amount of matter changes.
Mass: how much matter in the sample
Weight: how gravity affects the mass
Volume: How much space the sample takes up
Energy: how much energy is contained within the matter
Size and Shape
Length, width, height: How long, high or wide the sample is 
Electrical charge: how much charge is stored within the matter.

5. Physical Change: For example:
Change in which the matter's physical properties are altered, but composition (what it is made up of) remains unchanged. The atomic structure of the molecules does not change.
For example:
If water is cooled or heated the density changes but it’s still water
When energy is changed it can change the state of matter (liquid solid or gas) but it still is the same kind of matter.
When hair is cut or dyed the length or color changes but it is still hair
When water, lemon and sugar are mixed together it makes lemonade but the water is still H2O and the sugar is still C12H22O11 and the lemon is still lemon.

6. Chemical Property:
Any characteristic that gives a sample of matter the ability/inability to undergo a change that alters its composition.
Examples:
Reactivity: How chemically stable matter is - Alkali metals react with water.
Flammability: How matter reacts to heat - Paper's ability to burn.
Acidity / Alkalinity: How acidic or basic something is
Corrosion: degradation of a material due to a reaction with its environment – batteries can corrode due to the reaction between two dissimilar metals.
Oxidation: How matter reacts to oxygen is a specific type of corrosion - Iron reacts with oxygen to form rust, apple turns brown, penny turns green
Catalysis: ability to increase reaction rate -
Heat of combustion: How much heat is released during burning
Toxicity: how poisonous something is to life.

7. Chemical Change:
Change in which one or more kinds of matter are transformed to new kinds of matter with altered compositions (Chemical Reaction).
Research : Is pH a physical or chemical property? What about smell?
Question If physical is pH or smell intensive or extensive?
