REVIEW MODULE 6
LEARNING GOAL
2d.) Investigate the effects of chemical change on physical properties of substances (e.g. rust, fire, respiration,
photosynthesis).
VOCABULARY:
1.) chemical change: A synonym for chemical reaction. A change that rearranges atoms into
new molecules and produces new substances with new properties.
2.) Products: The substances that are produced due to a chemical change. Another word
for new substance. EXAMPLE: white powder,
3.) Reactants: The substances that enter into a chemical change. The starting substances.

ESSENTIAL QUESTIONS
S1O2d- 1.) Explain why chemical changes change BOTH chemical and physical properties.
Use the the words reactants and products.
S1O2d-2.) Explain at least one example of how a chemical change changed both physical
properties and chemical properties from your demos. Describe the properties before AND after.
FORMATIVE QUIZ 6a

physical properties.
b. The same substances are present with the same chemical properties
andsome different physical properties.
c. The same substances are present with new chemical properties and
some different physical properties and physical properties.

properties.
b. They change only physical properties
c. They change neither chemical properties
not physical properties
d. They change only chemical properties
7.) Use the table below to help answer the following question. An
experiment was done by mixing together various substances. When
these substances were mixed some of them went through a chemical
change. Use the physical properties data below to determine which
went through a chemical change.

ESSENTIAL QUESTIONS KEY
S1O2d- 1.) Explain why chemical changes change BOTH chemical and physical properties. Use the the words reactants
and products. During a chemical change the reactants change into completely different substances. These new substances
are called products and they have completely different properties because they are new substances.
S1O2d-2.) Explain at least one example of how a chemical change changed both physical properties and chemical
properties from your demos. Describe the properties before AND after.
When we burned the sugar it was a chemical change. Combustion occurred and created a brand new substance. The sugar
ahd a physical property of being grainy and white. The product was black and gooey. These are physical properties and
they were different before and after the chemical change. Also, the sugar had the chemical property of being combustable,
but the new black substance was not combustible.
