2. C3.3 Properties and changes
Physical property:
A description of a substance that does not involve forming a new substance; for example, color, texture, density, smell, solubility, taste, melting point, and physical state
Chemical Property
A description of what a substance does as it changes into one or more new substances. Examples include
Flammable: Gasoline burns easily if ignited
Corrosive: Discarded batteries in landfill sites break down readily when they come in contact with groundwater.

3. C3.3 Physical & chemical changes
Physical change:
A change that does not produce a new substance. Many can be reversed, others can not.
Melting, evaporation, condensation, sublimation, dissolving
Chemical change:
The change that a substance goes through to produce a new substance (or more than one new substance) is called a chemical change. Many cannot be reversed, but some can.

4. C3.3 & 2.5 Clues of chemical changes
A new color appears
A change in odour
The production of light
Heat or light is produced or absorbed
A change in temperature
Bubbles of gas are formed
A solid material (a precipitate) forms in a liquid
The change is (generally) difficult to reverse.

5. C3.3 & 2.5 Clues of chemical changes
Physical and Chemical Change Assignment
Physical Changes
Find, bring in, and show the class an example of a physical change
Explain why it is a physical change (using notes from handout)
Chemical Changes
Find, bring in, and show the class a SAFE/COMMON example of a chemical change (use a video if necessary)
Explain why it is a chemical change (using notes from handout). What evidence do you have?
Must hand in a one page document describing both examples. Include a justification as to why they are physical/chemical changes using section 5.1 as a guide.

6. C1.1 Hazardous Products and workplace safety

C1.1: Analyze, on the basis of research, various safety and environmental issues associated with chemical reactions and their reactants and or products (WHMIS, safety as a firefighter, combustion)
C1.2: How an understanding of properties of chemical substances and their reactions can be applied to solve environmental challenges
(neutralizing acid spills; cleaning up chemicals)
