SEPARATING MIXTURES |
|
• A mixture combines two or more materials
that retain their own properties.
• A solution forms when a material
dissolves in a liquid (solvent) and cannot
be retrieved with a filter.
• All mixtures can be separated based
on the properties of the constituent
substances.
• Evaporation can separate a liquid from a
solid in a solution.
• Crystal form can be used to identify
substances. |
• Mixtures
• Taking Mixtures Apart
• Summary: Separating Mixtures
• Science Notebook: Students record
how they assembled mixtures
and the methods used to separate
mixtures.

REACHING SATURATION |
|
• Solubility is the property that substances
have of dissolving in solvents. Solubility
is different for different materials and
can change with temperature and
solvent.
• Solubility can be used to differentiate
and identify substances.
• A solution is saturated when a solvent
has dissolved as much solute as possible.
• Decompression sickness is caused by
supersaturation of the gas nitrogen in
blood. |
• Solutions Up Close
• The Bends
• Summary: Reaching Saturation
• Science Notebook: Students follow
a procedure and record results. They
use solubility data to determine the
identity of a mystery substance.

FIZZ QUIZ |
|
• When a change results from mixing
two or more materials, that change
is a chemical reaction, which can be
represented with chemical formulas and
chemical equations.
• Atoms are the fundamental building
blocks of matter; all substances are
composed of atoms.
• Atoms in reactants rearrange during
reactions to form new substances.
• Atoms combine to form molecules.
Molecules are the fundamental units of
substances. |
• When Substances Change
• Chemical Formulas
• Equations
• Summary: Fizz Quiz
• Science Notebook: Students record
reaction observations and rationale
for identification of products. They
complete chemical equations to
demonstrate production of new
substances and conservation of atoms.

ELEMENTS |
|
• Earth has 90 naturally occurring
elements, each defined by a unique atom.
• Most matter on Earth is made from only a
few elements.
• Most elements on Earth are metals;
metals share properties of malleability
and conduction of heat and Electricity.
• The periodic table provides information
about the composition of an element’s
atom and the element’s chemical
properties.
• Atoms and molecules can be imaged with
scanning tunneling microscopes. |
• Organizing the Elements
• The Periodic Table of the Elements
• Metals
• Earth Elements
• New Technologies
• Ask a Chemist
• Summary: Elements
• Science Notebook: Students
describe metals and record the
occurrence of elements in ordinary
materials. |
