The student is expected to

describe and record examples of interactions and dependence between living and nonliving components in terrariums or aquariums; and

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.1.12.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.

S.1.12.A

classify living and nonliving things based upon whether they have basic needs and produce young;

S.1.12.B

describe and record examples of interactions and dependence between living and nonliving components in terrariums or aquariums; and

S.2.12.A

describe how the physical characteristics of environments, including the amount of rainfall, support plants and animals within an ecosystem;

S.3.12.A

explain how temperature and precipitation affect animal growth and behavior through migration and hibernation and plant responses through dormancy;

S.5.12.A
observe and describe how a variety of organisms survive by interacting with biotic and abiotic factors in a healthy ecosystem;
S.6.12.A
investigate how organisms and populations in an ecosystem depend on and may compete for biotic factors such as food and abiotic factors such as availability of light and water, range of temperatures, or soil composition;
AQUA.9.C
explain how tidal cycles influence intertidal ecology.
ENVIR.5.C
evaluate the effects of fluctuations in abiotic factors on local ecosystems and local biomes;
ENVIR.5.D
measure the concentration of dissolved substances such as dissolved oxygen, chlorides, and nitrates and describe their impacts on an ecosystem;

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.
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.

This is an introduction to the interdependence between organisms and their environment. The ecosystem comprises plants, animals, and the abiotic (nonliving) factors they depend on to meet their basic needs.

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.

Stable systems within an aquarium or terrarium do not require external inputs such as food or water. Most aquariums and terrariums are unstable systems that require food and water for the organisms and the cleaning of waste products.

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.
