Science.8.11.A

Previous Next
The student is expected to use scientific evidence to describe how natural events, including volcanic eruptions, meteor impacts, abrupt changes in ocean currents, and the release and absorption of greenhouse gases influence climate;

A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”

SCIENCE.8.11.A — 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.

S.4.10.C

differentiate between weather and climate.

S.8.10.A
describe how energy from the Sun, hydrosphere, and atmosphere interact and influence weather and climate;
S.8.11.A
use scientific evidence to describe how natural events, including volcanic eruptions, meteor impacts, abrupt changes in ocean currents, and the release and absorption of greenhouse gases influence climate;
S.8.11.B

use scientific evidence to describe how human activities, including the release of greenhouse gases, deforestation, and urbanization, can influence climate; and

IPC.8.D
construct and communicate an evidence-based explanation of the environmental impact of the end-products of chemical reactions such as those that may result in degradation of water, soil, air quality, and global climate change.
EARTH.11.A
analyze how energy transfer through Milankovitch cycles, albedo, and differences in atmospheric and surface absorption are mechanisms of climate;
EARTH.11.C
model how greenhouse gases trap thermal energy near Earth's surface;
ENVIR.9.D
describe how temperature inversions have short-term and long-term effects, including El Nio and La Nia oscillations, ice cap and glacial melting, and changes in ocean surface temperatures; and
ENVIR.9.E
analyze the impact of natural global climate change on ice caps, glaciers, ocean currents, and surface temperatures.
EARTH.11.G
describe how changing surface-ocean conditions, including El Nio-Southern Oscillation, affect global weather and climate patterns.
ENVIR.10.E
distinguish between the causes and effects of global warming and ozone depletion, including the causes, the chemicals involved, the atmospheric layer, the environmental effects, the human health effects, and the relevant wavelengths on the electromagnetic spectrum (IR and UV).

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.
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.

The particles released into the air by volcanic eruptions and meteor impacts (cause) can affect climate by blocking solar radiation (thermal and light energy) from reaching Earth's surface.

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.

Earth's climate system consists of the hydrosphere (water), the atmosphere (air), the geosphere (solid part of Earth), and the biosphere (the living components). Natural events like volcanic eruptions or abrupt changes in ocean currents may influence climate by impacting the interaction between the parts of the climate system.

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.
