 A scientist combined two liquids into a flask. The
temperature of the flask increased, the combined
substance started bubbling, and a strong odor was given
off. Was this an example of a mixture or a compound and
why?
a.
It is a mixture because the temperature of the flask
increased, and there was an odor.
b. It is a compound because there were two liquids combined
together.
c. It is a compound because a chemical reaction occurred.

REVIEW:
What is an ELEMENT?
 A substance composed
of a single kind of atom.
 Cannot be broken down
into another substance
by chemical or physical
means.
Review:
What is a COMPOUND
 A substance in which
two or more
different elements
are CHEMICALLY
bonded together.
Review:
What is a MIXTURE
 Two or more substances
that are mixed together
but are NOT chemically
bonded.

Hands-On
Lab
Procedure:
 With your lab group, go to each lab table and compare and
contrast the different items in the dishes.
 Categorize the materials in each dish as element, mixture, or
compound and record the information in your data tables.
 Discuss your lists.
Investigating questions:
 On your lab sheet, describe the three types of matter.
 Give some examples of elements, mixtures, and compounds.
 Explain the different properties of each group of materials.
NOTE:
Think of the washer, bolt , and nut as an individual atom!
Engineering Connection:
 New materials are one of the greatest achievements
of every age.
 Material engineers are focused on understanding
different materials so that they can create new
materials with desired properties. For, example they
take advantage of the varying strengths and abilities
of different materials to make composites that are
engineered from two or more materials with
different PHYSICAL and CHEMICAL properties.
