PS.1 The student will demonstrate an understanding of scientific and engineering practices by

PS.2 The student will investigate and understand that matter is composed of atoms. Key ideas include

  • PS.2.a our understanding of atoms has developed over time;

  • PS.2.b the periodic table can be used to predict the chemical and physical properties of matter; and

  • PS.2.c the kinetic molecular theory is used to predict and explain matter interactions.

PS.3 The student will investigate and understand that matter has properties and is conserved in chemical and physical processes. Key ideas include

PS.4 The student will investigate and understand that the periodic table is a model used to organize elements based on their atomic structure. Key uses include

  • PS.4.a symbols, atomic numbers, atomic mass, chemical groups (families), and periods are identified on the periodic table; and

  • PS.4.b elements are classified as metals, metalloids, and nonmetals.

PS.5 The student will investigate and understand that energy is conserved. Key ideas include

PS.6 The student will investigate and understand that waves are important in the movement of energy. Key ideas include

  • PS.6.a energy may be transferred in the form of longitudinal and transverse waves;

  • PS.6.b mechanical waves need a medium to transfer energy;

  • PS.6.c waves can interact; and

  • PS.6.d energy associated with waves has many applications.

PS.7 The student will investigate and understand that electromagnetic radiation has characteristics. Key ideas include

  • PS.7.a electromagnetic radiation, including visible light, has wave characteristics and behavior; and

  • PS.7.b regions of the electromagnetic spectrum have specific characteristics and uses.

PS.8 The student will investigate and understand that work, force, and motion are related. Key ideas include

PS.9 The student will investigate and understand that there are basic principles of electricity and magnetism. Key ideas include

  • PS.9.a an imbalance of charge generates static electricity;

  • PS.9.b materials have different conductive properties;

  • PS.9.c electric circuits transfer energy;

  • PS.9.d magnetic fields model the magnetic effects of certain materials;

  • PS.9.e electric current and magnetic fields are related; and

  • PS.9.f many technologies use electricity and magnetism.
