SCIENCE.2.12.C — 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.13.C

identify and record the changes from seed, seedling, plant, flower, and fruit in a simple plant life cycle; and

S.1.13.B

record observations of and describe basic life cycles of animals, including a bird, a mammal, and a fish; and

S.2.12.C

explain and demonstrate how some plants depend on other living things, wind, or water for pollination and to move their seeds around.

S.2.13.D

investigate and describe some of the unique life cycles of animals where young animals do not resemble their parents, including butterflies and frogs.

S.3.13.B

explore, illustrate, and compare life cycles in organisms such as beetles, crickets, radishes, or lima beans.

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.

Patterns occur in the structures of flowers and seeds based on the pollination method and method of seed dispersal.

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 structure of the seed or flower (cause) determines the way the seed is transported or flower is pollinated (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 system includes the flower, method of pollination, seed, and method of dispersal. Each part of the system interacts to allow plants to reproduce.

Relationship between structure and function

A structure is an organized arrangement of particles,
parts, or elements in a substance, body, or entity. A function is the purpose or reason for something to exist in a system. The function of a structure depends on the shapes of and relationships among its essential parts. It is important to note that in kindergarten – grade 2, students focus on structures as an organized arrangement of parts within an organism or object.

The structure of a seed or flower functions to allow the seed to be transported or the flower to be pollinated.

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.
