Grade 5

(5.6) Science concepts. The student knows that some change occurs in cycles.

The student is expected to:

1. identify events and describe changes that occur on a regular basis such as in daily, weekly, lunar, and seasonal cycles;
2. identify the significance of the water, carbon, and nitrogen cycles; and
3. describe and compare life cycles of plants and animals.

(5.11) Science concepts. The student knows that certain past events affect present and future events.

The student is expected to:

1. identify and observe actions that require time for changes to be measurable, including growth, erosion, dissolving, weathering, and flow;
2. draw conclusions about "what happened before" using data such as from tree-growth rings and sedimentary rock sequences; and
3. identify past events that led to the formation of the Earth's renewable, non-renewable, and inexhaustible resources.

(5.12) Science concepts. The student knows that the natural world includes earth materials and objects in the sky.

The student is expected to:

1. interpret how land forms are the result of a combination of constructive and destructive forces such as deposition of sediment and weathering;
2. describe processes responsible for the formation of coal, oil, gas, and minerals;
3. identify the physical characteristics of the Earth and compare them to the physical characteristics of the moon; and
4. identify gravity as the force that keeps planets in orbit around the Sun and the moon in orbit around the Earth.

Grade 6

(6.5) Scientific concepts. The student knows that systems may combine with other systems to form a larger system.

The student is expected to:

1. identify and describe a system that results from the combination of two or more systems such as in the solar system; and
2. describe how the properties of a system are different from the properties of its parts.

(6.6) Science concepts. The student knows that there is a relationship between force and motion.

The student is expected to:

1. identify and describe the changes in position, direction of motion, and speed of an object when acted upon by force;
2. demonstrate that changes in motion can be measured and graphically represented; and
3. identify forces that shape features of the Earth including uplifting, movement of water, and volcanic activity.

(6.13) Science concepts. The student knows components of our solar system.

The student is expected to:

1. identify characteristics of objects in our solar system including the Sun, planets, meteorites, comets, asteroids, and moons; and
2. describe types of equipment and transportation needed for space travel.

(6.14) Science concepts. The student knows the structures and functions of Earth systems.

The student is expected to:

1. summarize the rock cycle;
2. identify relationships between groundwater and surface water in a watershed; and
3. describe components of the atmosphere, including oxygen, nitrogen, and water vapor, and identify the role of atmospheric movement in weather change.

Grade 7

(7.8) Science concepts. The student knows that complex interactions occur between matter and energy.

The student is expected to:

1. illustrate examples of potential and kinetic energy in everyday life such as objects at rest, movement of geologic faults, and falling water; and
2. identify that radiant energy from the Sun is transferred into chemical energy through the process of photosynthesis.

(7.13) Science concepts. The student knows components of our solar system.

The student is expected to:

1. identify and illustrate how the tilt of the Earth on its axis as it rotates and revolves around the Sun causes changes in seasons and the length of a day; and
2. relate the Earth's movement and the moon's orbit to the observed cyclical phases of the moon.

(7.14) Science concepts. The student knows that natural events and human activity can alter Earth systems.

The student is expected to:

1. describe and predict the impact of different catastrophic events on the Earth;
2. analyze effects of regional erosional deposition and weathering; and
3. make inferences and draw conclusions about effects of human activity on Earth's renewable, non-renewable, and inexhaustible resources.

Grade 8

(8.10) Science concepts. The student knows that complex interactions occur between matter and energy.

The student is expected to:

1. illustrate interactions between matter and energy including specific heat;
2. describe interactions among solar, weather, and ocean systems; and
3. identify and demonstrate that loss or gain of heat energy occurs during exothermic and endothermic chemical reactions.

(8.12) Science concepts. The student knows that cycles exist in Earth systems.

The student is expected to:

1. analyze and predict the sequence of events in the lunar and rock cycles;
2. relate the role of oceans to climatic changes; and
3. predict the results of modifying the Earth's nitrogen, water, and carbon cycles.

(8.13) Science concepts. The student knows characteristics of the universe.

The student is expected to:

1. describe characteristics of the universe such as stars and galaxies;
2. explain the use of light years to describe distances in the universe; and
3. research and describe historical scientific theories of the origin of the universe.

(8.14) Science concepts. The student knows that natural events and human activity can alter Earth systems.

The student is expected to:

1. predict land features resulting from gradual changes such as mountain building, beach erosion, land subsidence, and continental drift;
2. analyze how natural or human events may have contributed to the extinction of some species; and
3. describe how human activities have modified soil, water, and air quality.
