Overview:

An atom is a tiny particle in matter, and atoms are made of protons, neutrons, and electrons. Some matter, like your body or your book, is made of lots of different kinds of atoms, but elements are made up of only one kind of atom.

The classroom resource provides a video that will explain atoms and how they are made of smaller particles called protons, electrons, and neutrons. This resource can provide background information for students before they construct their own models and/or carry out their own investigations. There is also a short test that can be used to assess students' understanding.

Content Standard(s):
Science
SC2015 (2015)
Grade: 5
1 ) Plan and carry out investigations (e.g., adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, evaporating salt water) to provide evidence that matter is made of particles too small to be seen.


NAEP Framework
NAEP Statement::
P4.3: Matter exists in several different states; the most common states are solid, liquid, and gas. Each state of matter has unique properties. For instance, gases are easily compressed while solids and liquids are not. The shape of a solid is independent of its container; liquids and gases take the shape of their containers.

NAEP Statement::
P4.4: Some objects are composed of a single substance; others are composed of more than one substance.

NAEP Statement::
P8.1: Properties of solids, liquids, and gases are explained by a model of matter that is composed of tiny particles in motion.

  • Particle
Knowledge:
Students know:
  • Matter is made of particles too small to be seen Matter too small to be seen still exists and may be detected by other means.
  • Gasses are made of matter particles that are too small to see, and are moving freely around in space (this can explain many observations, including the inflation and the shape of the balloon, and the effects of air on larger particles or objects).
  • The behavior of a collection of many tiny particles of matter and observable phenomena involving bulk matter (e.g., an expanding balloon, evaporating liquids, substances that dissolve in a solvent, effects of wind).
  • There is a relationship between bulk matter and tiny particles that cannot be seen.
Skills:
Students are able to:
  • Identify the phenomenon under investigation.
  • Identify evidence that addresses the purpose of the investigation.
  • Collaboratively plan the investigation.
  • Collect and analyze the data.
Understanding:
Students understand that:
  • Natural objects exist from the very small to the immensely large.

Science
SC2015 (2015)
Grade: 8
Physical Science
1 ) Analyze patterns within the periodic table to construct models (e.g., molecular-level models, including drawings; computer representations) that illustrate the structure, composition, and characteristics of atoms and molecules.


NAEP Framework
NAEP Statement::
P12.2: Electrons, protons, and neutrons are parts of the atom and have measurable properties, including mass and, in the case of protons and electrons, charge. The nuclei of atoms are composed of protons and neutrons. A kind of force that is only evident at nuclear distances holds the particles of the nucleus together against the electrical repulsion between the protons.

NAEP Statement::
P12.3: In the Periodic Table, elements are arranged according to the number of protons (called the atomic number). This organization illustrates commonality and patterns of physical and chemical properties among the elements.

NAEP Statement::
P8.3a: All substances are composed of 1 or more of approximately 100 elements.

NAEP Statement::
P8.3b: The periodic table organizes the elements into families of elements with similar properties.

NAEP Statement::
P8.4a: Elements are a class of substances composed of a single kind of atom.

NAEP Statement::
P8.4b: Compounds are composed of two or more different elements.

NAEP Statement::
P8.5b: Metals and acids are examples of such classes.

NAEP Statement::
P8.5c: Metals are a class of elements that exhibit common physical properties such as conductivity and common chemical properties such as reacting with nonmetals to produce salts.

Knowledge:
Students know:
  • Elements are substances composed of only one type of atom each having an identical number of protons in each nucleus.
  • Atoms are the basic units of matter and the defining structure of elements.
  • Atoms are made up of three particles: protons, neutrons and electrons.
  • The number of protons in an atom's nucleus is equal to the atomic number.
  • The periodic table arranges all the known elements in an informative array.
  • Elements are arranged left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass.
  • Rows in the periodic table are called periods. As one moves from left to right in a given period, the chemical properties of the elements slowly change.
  • Columns in the periodic table are called groups. Elements in a given group in the periodic table share many similar chemical and physical properties.
  • The period number of an element signifies the highest energy level an electron in that element occupies (in the unexcited state). The number of electrons in a period increases as one traverses down the periodic table; therefore, as the energy level of the atom increases, the number of energy sub-levels per energy level increases.
  • A molecule is formed when two or more atoms bond together chemically.
  • A chemical bond is the result of different behaviors of the outermost or valence electrons of atoms.
  • Ionic bonds are the result of an attraction between ions that have opposite charges. Ionic bonds usually form between metals and nonmetals; elements that participate in ionic bonds are often from opposite ends of the periodic table. One example of a molecule that contains an ionic bond is table salt, NaCl.
  • Covalent bonds form when electrons are shared between atoms rather than transferred from one atom to another. The two bonds in a molecule of carbon dioxide, CO2, are covalent bonds.
  • Metallic bonds exist only in metals, such as aluminum, gold, copper, and iron. In metals, each atom is bonded to several other metal atoms, and their electrons are free to move throughout the metal structure. This special situation is responsible for the unique properties of metals, such as their high conductivity.
Skills:
Students are able to:
  • Analyze patterns within the periodic table to construct models of atomic and molecular structure, composition, and characteristics.
  • Identify the relevant components of the atomic and molecular models.
  • Describe relationships between components of the atomic and molecular models.
Understanding:
Students understand that:
  • Patterns in the periodic table predict characteristic properties of elements. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.
  • The structure, composition, and characteristics of atoms and molecules are dependent upon their position in the periodic table.
