Science.7.9.B

The student is expected to describe how gravity governs motion within Earth's solar system; 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.7.9.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.7.9.B
describe how gravity governs motion within Earth's solar system; and
IPC.5.E
construct and communicate an explanation based on evidence for how changes in mass, charge, and distance affect the strength of gravitational and electrical forces between two objects.
PHYS.5.H
describe and calculate, using scientific notation, how the magnitude of force between two objects depends on their masses and the distance between their centers, and predict the effects on objects in linear and orbiting systems using Newton's law of universal gravitation.
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;

SCIENCE.7.9.B — Breakout of skills

Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.

The student is expected to
describe how gravity governs motion within Earth's solar system

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 greater the mass (cause) of an object, the greater the gravitational pull (effect) it has on surrounding objects.

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.

There is a direct proportional relationship between the gravitational pull of celestial bodies and their mass.

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 Solar System's gravity controls the pattern of movements among the celestial bodies (parts).

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.
