SCIENCE.7.11.B — Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

Previous grade

S.1.10.C

compare the properties of puddles, ponds, streams, rivers, lakes, and oceans, including color, clarity, size, shape, and whether it is freshwater or saltwater; and

S.4.10.A

describe and illustrate the continuous movement of water above and on the surface of Earth through the water cycle and explain the role of the Sun as a major source of energy in this process;

S.5.10.A

explain how the Sun and the ocean interact in the water cycle and affect weather;

S.7.11.A

analyze the beneficial and harmful influences of human activity on groundwater and surface water in a watershed; and

S.7.11.B

describe human dependence and influence on ocean systems and explain how human activities impact these systems.

AQUA.10.A

identify sources of water in a watershed, including rainfall, groundwater, and surface water;

AQUA.10.B

identify factors that contribute to how water flows through a watershed;

AQUA.10.C

analyze water quantity and quality in a local watershed or aquifer; and

AQUA.12.A

differentiate among freshwater, brackish, and marine ecosystems; and

ENVIR.6.B

relate how water sources, management, and conservation affect water uses and quality;

EARTH.9.B

investigate and model how surface water and ground water change the lithosphere through chemical and physical weathering and how they serve as valuable natural resources;

EARTH.9.D

evaluate how weather and human activity affect the location, quality, and supply of available freshwater resources.

EARTH.10.A

describe how the composition and structure of the oceans leads to thermohaline circulation and its periodicity;

EARTH.10.B

model and explain how changes to the composition, structure, and circulation of deep oceans affect thermohaline circulation using data on energy flow, ocean basin structure, and changes in polar ice caps and glaciers; and

EARTH.10.C

analyze how global surface ocean circulation is the result of wind, tides, the Coriolis effect, water density differences, and the shape of the ocean basins.

ENVIR.10.A

identify sources of emissions in air, soil, and water, including point and nonpoint sources;

Recurring themes and concepts — Connections to the content

Recurring themes and concepts provide a connective structure for scientific ideas across disciplines. The connection(s) below show some ways that teachers can help students understand how the content they are learning fits into the broader understanding of science. These connections do not represent all possible connections that might be made but highlight some that are appropriate for this grade level.

Patterns

Patterns are regular sequences that can be found throughout nature.

Patterns can be seen in human trade routes, migration of oceanic organisms, and ocean currents.

Cause-and-effect relationships

Cause-and-effect relationships are relationships between two or more variables or phenomena whereby one variable or event leads to a predictable response. Events have causes—sometimes simple, sometimes multi-faceted.

When humans harvest too many organisms of the same species (cause), then the population of that species cannot recover to sustainable levels (effect). When fertilizer runoff from human agriculture enters the ocean (cause), it can cause algal blooms (effect), depleting the dissolved oxygen in the water and causing dead zones.

Model the interdependence and parts of a system

A system is a whole made of parts that work together. It has components and boundaries. It can interact with or be part of other systems.

The ocean system consists of the biotic and abiotic factors in the ocean and the currents that move them around. Human dependence on ocean systems for food, transportation, and energy production can impact parts of the system.

Stability and change

Stability describes a system that does not change at the observed scale. In a stable system, a small disturbance will die out and the system will return to a stable state. Change in the system can come from modifying a factor or condition.

Ocean systems have been stable for millennia; however, whaling in the 19th century (change) caused a decline in top predator populations, destabilizing oceanic food webs.

Cross-curricular Connections

The cross-curricular connections are designed to help educators make content connections between the science TEKS and math, English language arts and reading, social studies, and technology applications. The standards below illustrate alignment between grade level content areas which may help educators develop cross-curricular lessons. These connections do not represent all possible connections that might be made.
