Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are
the smallest unit of an element and are composed of sub-atomic particles (electrons surrounding a
nucleus containing protons and neutrons).
Subject Area: Science
Grade: 8
Body of Knowledge: Physical Science
Big Idea: Properties of Matter - A. All objects and substances in the world are made of matter.
Matter has two fundamental properties: matter takes up space and matter has mass which gives it
inertia.
B. Objects and substances can be classified by their physical and chemical properties. Mass is the
amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of
attraction (gravitational force) between an object and Earth.
The concepts of mass and weight are complicated and potentially confusing to elementary students.
Hence, the more familiar term of "weight" is recommended for use to stand for both mass and
weight in grades K-5. By grades 6-8, students are expected to understand the distinction between
mass and weight, and use them appropriately.
Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass”
is recommended for grades K-2.
Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In
grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not
weight) is used to compare properties of solids, liquids and gases.

product in this lesson will showcase the student’s conceptual
understanding of the atomic structure in a computer science
medium.
Students take visitors on a trip through time to view the
development of the atomic theory. During the presentation they list

scientists who contributed to our understanding, give dates, and
display diagrams that represent the atom in various stages of its
development.
This lesson provides students with the basic foundations of atomic
theory and a simple understanding of the periodic table. It provides
an easy-to-understand Prezi presentation before leading students
Build An Atom
into an easy and fun atom building simulation. Assessments are
scored by the progam. A vocabulary website is also provided. It can
be used on iPads or in a computer lab.
Students will be able to explain what an atom is and what its
subatomic particles are. Students will be able to read and locate the
number of protons for each element on the periodic table. Knowing

the location of the protons, they will gain knowledge about the
electrons and the neutrons. They will also be able to model an atom
and properly locate the protons, neutrons, and electrons.
Students learn the charge and location of subatomic particles by

dressing as them and creating an atom model in the classroom.
Through this engaging activity students work as a group to create
models of isotopes with stickers and construction paper. Students
Mystery Isotopes
also use models created by their peers to analyze the number of
subatomic particles and determine isotopes' names. All worksheets
and data collection sheets are included.
In this Model Eliciting Activity (MEA), students will use their
knowledge of the organization of the periodic table and the basic
Periodic Table - Atoms and
properties of atoms to determine which elements should be used to
Bonding
develop compounds with two atoms of different elements. Students
must determine the number of protons, neutrons, and electrons in a
neutrally charged atom of an element using the periodic table. They
must also determine which elements will likely bond together using
their location on the periodic table. Students completing this
MEA will develop two short essay responses to a client in the
scientific industry.
This lesson will teach the concept of differences between stable

Description
This article is intended to support reading in the content area. The
article provides a chronological description of the development of
the atomic theory. Beginning with debates by Greek philosophers
in the sixth century B.C., the various beliefs about atoms are
explained. For around 2000 years, the subject lay dormant, until
John Dalton developed his atomic theory in the 1800s. Delving into
tests of Dalton's theory, the author explains how scientists, over
time, developed what we now know as the modern day atomic
theory.
This informational text resource is intended to support reading in
the content area. This text examines how humans and all things
around us are made of elements created in stars. The article
references fusion, the powerful collision of enormous stars, and the
intense explosion of supernovas. All of this is tied to the creation of
heavier elements that hurtle through space, to be reassembled as
distant solar systems.
