The document discusses key concepts related to physical and chemical changes, including: - The student will learn to distinguish between physical and chemical changes and understand chemical formulas and bond types. - A physical change alters a substance's size, shape, or state but not its chemical makeup, while a chemical change produces a new substance. - The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction, though the substance and form may change. - A chemical formula represents the elements in a compound using symbols, such as CO2 for carbon dioxide. A chemical equation models a reaction using formulas.

1. Notes

2.  The student will:
 Distinguish the difference
between a chemical and a physical
change
Investigate and understand
physical and chemical changes in
matter

3.  Investigate and understand chemical
formulas and the types of bonds
found in simple compounds
 Understand the Law of Conservation
of Mass

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

5.  States:
 Mass/matter is
neither lost or
gained during a
reaction, though
it may change in
substance, form,
phase or state

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

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

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

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

10.  Located on the
left side of the
equation, these
chemicals
combine/bond
together or react
with each other
Carbon (C) + 2
Oxygen atoms
(O2)
▪C + O2 CO2

11.  Located on the
right side of the
equation, this is
the outcome of
the reaction
C + O2  CO2
▪Carbon (C )+ 2
Oxygen atoms (O2)
= Carbon Dioxide
(CO2)

12. Activity Chemical list Clues to Change
How will you build opportunities for repeated practice of the skill into your plan?
What methods will you use to get feedback on your performance (from other professionals and from students)?
What data will you collect to demonstrate your progress?
What indicators will demonstrate that you have achieved (or made progress) toward) your goal?

13. Now lets work on the Lab
activities

14. Notes (Cont,)

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

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

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

18. One or more of these
occurs

19. Color Change

20. Gas Formation
(Bubbles/Fizzing)

21. Temperature Change
(Increase/Decrease)

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