1. Physical Science
• Review (from grade 5): Structure of atoms: protons,
neutron, electrons
1. Mixtures of substances can be separated based on
their properties such as solubility, boiling points,
magnetic properties, and densities
Molecules
Compounds are formed by combining two or more
elements and have properties different from the
constituent elements.
• Early theories of matter
The early Greek theory of four elements: earth, air,
fire, and water
Later theories of Democritus: everything is made of
atoms and nothing else (“atom” in Greek means that
which can’t be cut or divided); atoms of the same kind
form a pure “element”
Alchemy in middle ages
• Start of modern chemistry
Lavoisier and oxygen: the idea that matter is not
gained or lost in chemical reactions John Dalton
revives the theory of the atom.
Mendeleev develops the Periodic Table, showing that
the properties of atoms of elements come in repeating
(periodic) groups.
Niels Bohr develops a model of the atom in shells that
hold a certain number of electrons. Bohr’s model, plus
the discovery of neutrons, helped explain the
Periodic Table: atomic number, atomic weight, and
isotopes.

A. Writing and Research
1. Oral Expression and Listening
• Expository writing: Write nonfiction essays that describe,
narrate, persuade, and compare and contrast.
1. Formal presentations require preparation and
effective delivery
• Write research essays, with attention to asking open-ended
questions gathering relevant data through library and field
research summarizing, paraphrasing, and quoting accurately
when taking notes defining a thesis (that is, a central
proposition, a main idea) organizing with an outline
2. Small and large group discussions rely on active
listening and the effective contributions of all
participants
integrating quotations from sources acknowledging sources
2. Reading for All Purposes
1. Literary elements, characteristics, and ideas are

interrelated and guide the comprehension of literary
and fictional texts
and avoiding plagiarism preparing a bibliography
B. Speaking and Listening
• Participate civilly and productively in group discussions.
2. Informational and persuasive texts are summarized
and evaluated
• Give a short speech to the class that is well-organized and
well-supported.
3. Purpose, tone, and meaning in word choices
influence literary, persuasive, and informational texts
• Demonstrate an ability to use standard pronunciation when
speaking to large groups and in formal circumstances, such
as a job interview
3. Writing and Composition
1. Composing literary and narrative texts that
incorporate a range of stylistic devices demonstrates
knowledge of genre features
2. Organization is used when composing informational
and persuasive texts
3. Editing writing for proper grammar, usage,
mechanics, and clarity improves written work
4. Research and Reasoning
1. Answering a research question logically begins with
obtaining and analyzing information from a variety of
sources
2. Logical information requires documented sources
3. Reasoned material is evaluated for its quality using
both its logic and its use of a medium

What Students Will Learn In Future Grades
• Review (from grade 5): Structure of atoms: protons,
neutron, electrons
Molecules
Compounds are formed by combining two or more elements
and have properties different from the constituent elements.
1. Physical Science
1. Identify and calculate the direction and magnitude
of forces that act on an object, and explain the results
in the object’s change of motion
2. There are different forms of energy, and those forms
of energy can be changed from one form to another –
but total energy is conserved
3. Distinguish between physical and chemical changes,
noting that mass is conserved during any change
4. Recognize that waves such as electromagnetic,
sound, seismic, and water have common
characteristics and unique properties
