Statement of Inquiry/IB Trait
STATEMENT OF INQUIRY: Everything in the universe, including
us, is made of matter and elements are the building blocks of all matter.
Discovering elements has helped scientists identify the things that
everything in our universe has in common and the relationships we share.
Discovering the benefits and harms of certain elements and compounds
has helped us understand our universe and the way in which it works.

Demonstrations/Observations
• Silently observe three
demonstrations.
• Write specific and detailed
observations about what
happens in your guided
notes.
• Think about what you think
these observations mean for
these substances – Are they
the same was they were
before? Has a new substance
formed?

Physical Changes
•
•
•
•
The change in the size, shape,
form, or state of matter that
does not change the matter’s
identity.
A new substance is not formed.
Examples: Dissolving, changes
in state of matter, size, melting
and boiling.
Non-examples: Color change,
formation of gas, temperature
change, precipitate formation.

Chemical Changes
•
•
•
•
Substances that make up the
matter change into other
substances with different
chemical and physical
properties.
A new substance is formed.
Examples: Precipitate (solid)
formed, temperature change,
color change, gas formation,
production of light
Non-examples: dissolving, state
of matter change, size change.
Follow along in textbook – pages 67-70

Evidence of Chemical Change
1. Formation of a gas.
a. Usually in the form of
bubbles or fizzing.
2. Formation of a precipitate.
a. A solid is formed when
two liquids are combined.
3. Color change
4. Production of light
a. Combustion – fire.
5. Temperature change
