1: Earth and Space Sciences

1.A: Describe how the positions and motions of the objects in the universe cause predictable and cyclic events.

1.A.1: Describe how objects in the Solar System are in regular and predictable motions that explain such phenomena as days, years, seasons, eclipses, tides and moon cycles.

2D Eclipse
3D Eclipse
Seasons Around the World
Seasons in 3D
Seasons: Earth, Moon, and Sun
Seasons: Why do we have them?

1.A.2: Explain that the gravitational force is the dominant force determining motions in the Solar System and in particular keeps the planets in orbit around the Sun.

Gravitational Force
Orbital Motion - Kepler's Laws
Tides

1.B: Explain that the universe is composed of vast amounts of matter, most of which is at incomprehensible distances and held together by gravitational force. Describe how the universe is studied by the use of equipment such as telescopes, probes, satellites and spacecraft.

1.B.7: Examine the life cycle of a star and predict the next likely stage of a star.

H-R Diagram

1.E: Describe the processes that contribute to the continuous changing of Earth's surface (e.g., earthquakes, volcanic eruptions, erosion, mountain building and lithospheric plate movements).

1.E.10: Explain that most major geological events (e.g., earthquakes, volcanic eruptions, hot spots and mountain building) result from plate motion.

Plate Tectonics

1.E.11: Use models to analyze the size and shape of Earth, its surface and its interior (e.g., globes, topographic maps, satellite images).

Building Topographical Maps
Reading Topographical Maps

1.E.12: Explain that some processes involved in the rock cycle are directly related to the thermal energy and forces in the mantle that drive plate motions.

Plate Tectonics
Rock Cycle

1.E.13: Describe how landforms are created through a combination of destructive (e.g., weathering and erosion) and constructive processes (e.g., crustal deformation, volcanic eruptions and deposition of sediment).

Rock Cycle

1.E.14: Explain that folding, faulting and uplifting can rearrange the rock layers so the youngest is not always found on top.

Plate Tectonics

1.E.15: Illustrate how the three primary types of plate boundaries (transform, divergent and convergent) cause different landforms (e.g., mountains, volcanoes, ocean trenches).

Plate Tectonics

2: Life Sciences

2.B: Describe the characteristics of an organism in terms of a combination of inherited traits and recognize reproduction as a characteristic of living organisms essential to the continuation of the species.

2.B.1: Describe that asexual reproduction limits the spread of detrimental characteristics through a species and allows for genetic continuity.

Cell Division

2.B.2: Recognize that in sexual reproduction new combinations of traits are produced which may increase or decrease an organism's chances for survival.

Evolution: Mutation and Selection
Microevolution
Natural Selection
Rainfall and Bird Beaks

2.B.3: Explain how variations in structure, behavior or physiology allow some organisms to enhance their reproductive success and survival in a particular environment.

Microevolution
Natural Selection

2.D: Explain how extinction of a species occurs when the environment changes and its adaptive characteristics are insufficient to allow survival (as seen in evidence of the fossil record).

2.D.4: Explain that diversity of species is developed through gradual processes over many generations (e.g., fossil record).

Human Evolution - Skull Analysis

2.D.5: Investigate how an organism adapted to a particular environment may become extinct if the environment, as shown by the fossil record, changes.

Human Evolution - Skull Analysis
Natural Selection

3: Physical Sciences

3.B: In simple cases, describe the motion of objects and conceptually describe the effects of forces on an object.

3.B.3: Explain that an unbalanced force acting on an object changes that object's speed and/or direction.

Inclined Plane - Simple Machine
Roller Coaster Physics
Uniform Circular Motion

3.D: Describe that energy takes many forms, some forms represent kinetic energy and some forms represent potential energy; and during energy transformations the total amount of energy remains constant.

3.D.4: Demonstrate that waves transfer energy.

Bohr Model of Hydrogen
Bohr Model: Introduction
Photoelectric Effect

3.D.5: Demonstrate that vibrations in materials may produce waves that spread away from the source in all directions (e.g., earthquake waves, sound waves).

Sound Beats and Sine Waves
