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.
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
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?
