Chemical Reactions
Within
the Chemical Reactions Unit, IPC students are expected
to distinguish between physical and chemical changes,
analyze energy changes within a chemical reaction,
balance reactions and investigate and identify Law of
Conservation of Mass.
Critical Questions:
- What evidence gives proof of physical and chemical
change of matter?
- How does the Law of Consevation apply to
chemistry?
- What are the types of chemical reactions?
Suggested Time Frame: 4 Weeks |

|
Distinguish between physical and
chemical changes including properties and evidence of change (IPC
8A, B). |
|
Apply the Law of Conservation
of Mass to balance chemical equations. Identify
reactants and products of chemical equations (IPC 8C).
|
|
Identify types of chemical
reactions including; synthesis, decomposition, single
displacement, double displacement and combustion (IPC 7D).
|
|
Analyze energy changes that
accompany chemical reactions such as those occurring in heat
packs, cold packs, and glow sticks to classify them as
endergonic and exergonic reactions. (IPC 8B, E) |
