Science.7.9.A

Previous Next
The student is expected to describe the physical properties, locations, and movements of the Sun, planets, moons, meteors, asteroids, comets, Kuiper belt, and Oort cloud;

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.7.9.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.3.9.B

identify the order of the planets in Earth's solar system in relation to the Sun.

S.7.9.A
describe the physical properties, locations, and movements of the Sun, planets, moons, meteors, asteroids, comets, Kuiper belt, and Oort cloud;
ASTRO.6.B
observe the movement of planets throughout the year and measure how their positions change relative to the constellations;
ASTRO.7.A
demonstrate the use of units of measurement in astronomy, including astronomical units and light years, minutes, and seconds;
ASTRO.7.B
model the scale, size, and distances of the Sun, Earth, and Moon system and identify the limitations of physical models; and
ASTRO.7.C
model the scale, sizes, and distances of the Sun and the planets in our solar system and identify the limitations of physical models.
ASTRO.11.A
relate Newton's law of universal gravitation and Kepler's laws of planetary motion to the formation and motion of the planets and their satellites;
ASTRO.11.B
explore and communicate the origins and significance of planets, planetary rings, satellites, asteroids, comets, Oort cloud, and Kuiper belt objects;
ASTRO.11.C
compare the planets in terms of orbit, size, composition, rotation, atmosphere, natural satellites, magnetic fields, and geological activity; and
ASTRO.13.G
illustrate how astronomers use geometric parallax to determine stellar distances and intrinsic luminosities; and
ASTRO.13.H
describe how stellar distances are determined by comparing apparent brightness and intrinsic luminosity when using spectroscopic parallax and the Leavitt relation for variable stars.
ASTRO.15.B
evaluate the limits of observational astronomy methods used to formulate the distance ladder;
ASTRO.16.C
evaluate the evidence of the existence of habitable zones and potentially habitable planetary bodies in extrasolar planetary systems;

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.

 Celestial bodies have orbital patterns. Additionally, similarities in physical properties (patterns) allow planets to be classified as inner or outer planets.

Scale, proportion, and quantity in systems

 It is important to consider how changes in scale, proportion, or quantity affect a system’s structure or performance. Scale refers to the size of an object in relation to another object or its environment. Proportion is the ratio of one quantity to another. Quantity is a count of a set of objects or a measurement of a substance.

 Planets can be compared with each other and the Sun (scale) by size and distance (quantity).

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 movement of each celestial body (parts) within the Solar System is dependent upon its proximity to other celestial bodies. For example, each moon in the Solar System revolves around a specific planet.

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.
