1. Notes

2.  The student will:
 Distinguish the difference between a
chemical and a physical change
 Investigate and understand physical
changes in matter
 Investigate and understand chemical
changes in matter
 Investigate and understand chemical
formulas and the types of bonds found in
simple compounds

3.  The Law of Conservation of
Mass/Matter
 Chemical Change
 Physical Change
 Chemical Formula
 Chemical Equation
 Reactant
 Product

4.  States that
mass/matter is
neither lost or
gained during a
reaction, though
it may change in
substance, form,
phase or state

5.  When a substance
changes its size or
shape or phase/state of
matter but still retains
the properties of the
original substance
 i.e.:
▪ Paper being torn
into little pieces

6.  When a new
substance is created
through the
combination of
chemicals or energy
 i.e.:
▪ Paper burning and
turning into ash
(carbon)

7.  The way a
substance or
compound is
expressed
symbolically
▪CO2 is Carbon
Dioxide
▪H2O isWater
▪C6H12O6 is
Glucose

8.  A math-like equation that shows
how chemicals are combined
C + O2  CO2
▪ means “Yields”

9.  The chemicals combined in a
chemical equation
 Located on the left side of the
equation
Carbon (C) + 2 Oxygen atoms
(O2)
▪2O+C CO2

10.  The final
outcome of a
chemical reaction
 Located on the
right side of the
equation, (right of
the yields symbol
)
C + O2  CO2
▪Carbon (C )+ 2
Oxygen atoms (O2)
= Carbon Dioxide
(CO2)

11. Activity Chemical list Clues to Change

12. Notes (Cont.)

13.  Simply mixing materials does not
always produce a chemical change.
There must be evidence of a
chemical change
▪Measurable
▪Observable

14.  Same substance only in a different:
 Shape
 Size
 Phase/State of Matter
▪ Solid
▪ Liquid
▪ Gas

15. A New substance must
be formed!!!!!!!

16. One or more of these
occurs

17. Color Change

18. Gas Formation
(Bubbles/Fizzing)

19. Temperature Change
(Increase/Decrease)

20. Precipitate Formation
▪An insoluble compound forms at
the bottom
