SCIENCE.6.9.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.3.9.A

construct models and explain the orbits of the Sun, Earth, and Moon in relation to each other; and

S.4.9.B

collect and analyze data to identify sequences and predict patterns of change in the observable appearance of the Moon from Earth.

S.6.9.B

describe and predict how the positions of the Earth, Sun, and Moon cause daily, spring, and neap cycles of ocean tides due to gravitational forces.

S.7.9.C

analyze the characteristics of Earth that allow life to exist such as the proximity of the Sun, presence of water, and composition of the atmosphere.

ASTRO.8.A

model how the orbit and relative position of the Moon cause lunar phases and predict the timing of moonrise and moonset during each phase;

ASTRO.8.B

model how the orbit and relative position of the Moon cause lunar and solar eclipses; and

ASTRO.8.C

examine and investigate the dynamics of tides using the Sun, Earth, and Moon model.

ASTRO.9.C

investigate the relationship between a planet's axial tilt, angle of incidence of sunlight, and concentration of solar energy; and

ASTRO.11.D

compare the factors essential to life on Earth such as temperature, water, gases, and gravitational and magnetic fields to conditions on other planets and their satellites.

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.

Daily tides occur in a pattern—approximately twice per day. The Sun-Earth-Moon system has a repeating pattern of motion.

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 the Sun, Moon, and Earth form a line (cause), there will be a spring tide (effect). When the positions of the Sun, Moon, and Earth form a right angle (cause), there will be a neap tide (effect).

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 gravitational pull between the Sun, Earth, and Moon (parts) impact tides on Earth within the Sun-Earth-Moon system. The frequency, height and duration of tides are determined by the location of each part of the system in relation to the other parts.

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.

Tides are a product of the stable cycle of the Moon's orbit around Earth combined with the Sun's gravitational pull.

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.
