• Physical Science
  • Structure and properties of matter
    • An element is composed of a single type of atom. (9-12)
    • When elements are listed in order according to the number of protons (called the atomic number), repeating patterns of physical and chemical properties identify families of elements with similar properties. (9-12)
    • The "Periodic Table" is a consequence of the repeating pattern of outermost electrons and their permitted energies. (9-12)
    • Bonds between atoms are created when electrons are paired up by being transferred or shared. (9-12)
    • A compound is formed when two or more kinds of atoms bind together chemically. (9-12)
    • The physical properties of compounds reflect the nature of the interactions among its molecules. (9-12)
    • The interactions among molecules are determined by the structure of the molecule, including the constituent atoms and the distances and angles between them. (9-12)
    • Solids, liquids, and gases differ in the distances and angles between molecules or atoms and therefore the energy that binds them together. (9-12)
    • Carbon atoms can bond to one another in chains, rings, and branching networks to form a variety of structures, including synthetic polymers, oils, and the large molecules essential to life. (9-12)
  • Structure of atoms
    • Matter is made of minute particles called atoms, and atoms are composed of even smaller components. (9-12)
    • The components of atoms have measurable properties, such as mass and electrical charge. (9-12)
    • Each atom has a positively charged nucleus surrounded by negatively charged electrons. (9-12)
    • The electric force between the nucleus and electrons holds the atom together. (9-12)
    • The atom's nucleus is composed of protons and neutrons, which are much more massive than electrons. (9-12)
    • When an element has atoms that differ in the number of neutrons, these atoms are called different isotopes of the element. (9-12)
  • Chemical Reactions
    • Chemical reactions occur all around us, for example in health care, cooking, cosmetics, and automobiles. (9-12)
    • Chemical reactions may release or consume energy. (9-12)
    • In some reactions, chemical bonds are broken by heat or light to form very reactive radicals with electrons ready to form new bonds. (9-12)
    • Reaction rates depend on how often the reacting atoms and molecules encounter one another, on the temperature, and on the properties--including shape--of the reacting species. (9-12)
  • Light, heat, electricity, and magnetism
    • Heat can move from one object to another by conduction.
  • Interactions of energy and matter
    • Each kind of atom or molecule can gain or lose energy only in particular discrete amounts and thus can absorb and emit light only at wavelengths corresponding to these amounts. (9-12)

• Science as Inquiry
  • Understandings about scientific inquiry
    • Mathematical tools and models guide and improve the posing of questions, gathering data, constructing explanations and communicating results. (9-12)

• History and Nature of Science
  • Nature of science
    • Scientists formulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models. Those ideas are not likely to change greatly in the future.

• Process Standards for Professional Development
  • Learning
    • Build on the teacher's current science understanding, ability, and attitudes. (NSES)
