Science.2.9.B

Previous Next
The student is expected to

observe objects in the sky using tools such as a telescope and compare how objects in the sky are more visible and can appear different with a tool than with an unaided eye.

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.2.9.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.K.9.B

observe, describe, and illustrate the Sun, Moon, stars, and objects in the sky such as clouds.

S.2.9.B

observe objects in the sky using tools such as a telescope and compare how objects in the sky are more visible and can appear different with a tool than with an unaided eye.

ASTRO.5.A
evaluate and communicate how ancient civilizations developed models of the universe using astronomical structures, instruments, and tools such as the astrolabe, gnomons, and charts and how those models influenced society, time keeping, and navigation;
ASTRO.5.C
describe and explain the historical origins of the perceived patterns of constellations and the role of constellations in ancient and modern navigation.
ASTRO.6.C
identify constellations such as Ursa Major, Ursa Minor, Orion, Cassiopeia, and constellations along the ecliptic and describe their importance; and
ASTRO.10.B
calculate the relative light-gathering power of different-sized telescopes to compare telescopes for different applications;
ASTRO.10.C
analyze the importance and limitations of optical, infrared, and radio telescopes, gravitational wave detectors, and other ground-based technology; and
ASTRO.10.D
analyze the importance and limitations of space telescopes in the collection of astronomical data across the electromagnetic spectrum.

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.
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. It is important to note that in kindergarten – grade 2, students will only describe objects in terms of size (scale) and quantity. 

A telescope has a magnification (scale), for example, 10x or 40x, that makes objects appear bigger or closer to their actual size and distance.

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 parts of a telescope or other tool (system) work together to change how objects appear.

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.
