Chemical vs. Physical

 

Today in class:

1) we went over the homework, Particulate Nature of Matter,

2) then we took a quiz,

3) got back our Observation labs,
4) mini in-class experiment (magnisum)

5) took notes on Physical&Chemical Properties&Changes,

6) and filled out a worksheet with our partner on Chemical vs. Physical Changes

 

 

Physical Properties

• Everything has its own physical properties.
• A physical property is something that does not change into something new.
• For example:
• Color, shape, texture

Physical Change

• Changes in the physical properties of a substance.
• Examples: 
• Snow turning into water
• Melting a penny

Chemical Properties

• How it reacts with other substances.
• What's the ratio?

Chemical Change

• A substance changes into a brand new substance.
• Atoms are rearranged.
• does NOT make more atoms!
• Bonds are broken, and new ones are formed.

Chemical Change of Magnisum ---> Magnisum oxide

Mini in-class experiment on the effects of oxygen on metal.
