Science.K.9.A

Previous Next
The student is expected to

identify, describe, and predict the patterns of day and night and their observable characteristics; 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.K.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.K.9.A

identify, describe, and predict the patterns of day and night and their observable characteristics; and

S.5.9

demonstrate that Earth rotates on its axis once approximately every 24 hours and explain how that causes the day/night cycle and the appearance of the Sun moving across the sky, resulting in changes in shadow positions and shapes.

ASTRO.6.A
observe, record, and analyze the apparent movement of the Sun, Moon, and stars and predict sunrise and sunset;
ASTRO.9.B
predict how changing latitudinal position affects the length of day and night throughout a planet's orbital year;

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.
 

There are patterns in the movement of objects in the sky and in the behaviors of plants and animals during daytime and nighttime. For example, owls are usually alert at night while squirrels are usually alert during the day.
 

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. 
 

The moon appears larger than the stars at night (relative scale).
 

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.

English Language Arts and Reading

ELAR.K.1.C share information and ideas by speaking audibly and clearly using the conventions of language

ELAR.K.5.C make and confirm predictions using text features and structures with adult assistance

ELAR.K.12.C gather information from a variety of sources with adult assistance

ELAR.K.12.D demonstrate understanding of information gathered with adult assistance

ELAR.K.12.E use an appropriate mode of delivery, whether written, oral, or multimodal, to present results

Technology Applications

TA.K.1.B identify simple patterns and make predictions based on the patterns
