Global Science - Unit 2 Standards

Dynamic Earth Processes 3. Plate tectonics operating over geologic time has changed the patterns of land, sea, and mountains on Earth's surface. As the basis for understanding this concept:
e. Students know there are two kinds of volcanoes: one kind with violent eruptions producing steep slopes and the other kind with voluminous lava flows producing gentle slopes.	· Volcano flow types Lava viscosity Gas & pressure
f.* Students know the explanation for the location and properties of volcanoes that are due to hot spots and the explanation for those that are due to subduction.	· Ring of fire/hot spots Subduction Volcano properties & locations
California Geology 9. The geology of California underlies the state's wealth of natural resources as well as its natural hazards. As a basis for understanding this concept:
b. Students know the principal natural hazards in different California regions and the geologic basis of those hazards.	Natural hazards such earthquake faults/volcanoes, tsunamis, erosion Location of faults/volcanic activity Pacific Ring of Fire
Atomic and Molecular Structure 1. The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept:
a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass.	Basic atomic structure, comparative sizes of subatomic particles Atomic number and mass Organization of periodic table relative to atomic number Isotopes
b. Students know how to use the periodic table to identify metals, semimetals, non-metals, and halogens.	Metals vs. semi-metals vs. non-metals
c. Students know how to use the periodic table to identify alkali metals, alkaline earth metals and transition metals, trends in ionization energy, electronegativity, and the relative sizes of ions and atoms.	Families of metals Trends as they occur on the periodic table (ionization energy, electronegativity, ion sizes)
d. Students know how to use the periodic table to determine the number of electrons available for bonding.	Valence electrons are those electrons are available for bonding Each family has a specific number of valence electrons

Atomic and Molecular Structure 1. The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept:
e. Students know the nucleus of the atom is much smaller than the atom yet contains most of its mass.	Basic atomic structure, comparative sizes of subatomic particles Atomic number and mass Organization of periodic table relative to atomic number Isotopes
