UT.7.I. Students will understand the structure of matter.


UT.7.II. Students will understand the relationship between properties of matter and Earth’s structure.

  • UT.7.II.1. Examine the effects of density and particle size on the behavior of materials in mixtures.


    • UT.7.II.1.a Compare the density of various objects to the density of known earth materials.

    • UT.7.II.1.b Calculate the density of earth materials (e.g., rocks, water, air).

    • UT.7.II.1.c Observe and describe the sorting of earth materials in a mixture based on density and particle size (e.g., sorting grains of sand of the same size with different densities, sort materials of different particle size with equal densities).

    • UT.7.II.1.d Relate the sorting of materials that can be observed in streambeds, road cuts, or beaches to the density and particle size of those materials.

    • UT.7.II.1.e Design and conduct an experiment that provides data on the natural sorting of various earth materials.

  • UT.7.II.2. Analyze how density affects Earth's structure.


    • UT.7.II.2.a Compare the densities of Earth's atmosphere, water, crust, and interior layers.

    • UT.7.II.2.b Relate density to the relative positioning of Earth’s atmosphere, water, crust, and interior.

    • UT.7.II.2.c Model the layering of Earth's atmosphere, water, crust, and interior due to density differences.

    • UT.7.II.2.d Distinguish between models of Earth with accurate and inaccurate attributes.

UT.7.III. Students will understand that the organs in an organism are made of cells that have structures and perform specific life functions.

  • UT.7.III.1. Observe and describe cellular structures and functions.


    • UT.7.III.1.a Use appropriate instruments to observe, describe, and compare various types of cells (e.g., onion, diatoms).

    • UT.7.III.1.b Observe and distinguish the cell wall, cell membrane, nucleus, chloroplast, and cytoplasm of cells.

    • UT.7.III.1.c Differentiate between plant and animal cells based on cell wall and cell membrane.
      Review Cells-1 practice
      Review Cells-2 practice

    • UT.7.III.1.d Model the cell processes of diffusion and osmosis and relate this motion to the motion of particles.

    • UT.7.III.1.e Gather information to report on how the basic functions of organisms are carried out within cells (e.g., extract energy from food, remove waste, produce their own food).

  • UT.7.III.2. Identify and describe the function and interdependence of various organs and tissues.


    • UT.7.III.2.a Order the levels of organization from simple to complex (e.g., cell, tissue, organ, system, organism).

    • UT.7.III.2.b Match a particular structure to the appropriate level (e.g., heart to organ, cactus to organism, muscle to tissue).

    • UT.7.III.2.c Relate the structure of an organ to its component parts and the larger system of which it is a part.

    • UT.7.III.2.d Describe how the needs of organisms at the cellular level for food, air, and waste removal are met by tissues and organs (e.g., lungs provide oxygen to cells, kidneys remove wastes from cells).

UT.7.IV. Students will understand that offspring inherit traits that make them more or less suitable to survive in the environment.

  • UT.7.IV.1. Compare how sexual and asexual reproduction passes genetic information from parent to offspring.


    • UT.7.IV.1.a Distinguish between inherited and acquired traits.

    • UT.7.IV.1.b Contrast the exchange of genetic information in sexual and asexual reproduction (e.g., number of parents, variation of genetic material).

    • UT.7.IV.1.c Cite examples of organisms that reproduce sexually (e.g., rats, mosquitoes, salmon, sunflowers) and those that reproduce asexually (e.g., hydra, planaria, bacteria, fungi, cuttings from house plants).

      Review Plants-4 practice

    • UT.7.IV.1.d Compare inherited structural traits of offspring and their parents.

  • UT.7.IV.2. Relate the adaptability of organisms in an environment to their inherited traits and structures.


UT.7.V. Students will understand that structure is used to develop classification systems.

  • UT.7.V.1. Classify based on observable properties.


    • UT.7.V.1.a Categorize nonliving objects based on external structures (e.g., hard, soft).

    • UT.7.V.1.b Compare living, once living, and nonliving things.

    • UT.7.V.1.c Defend the importance of observation in scientific classification.

    • UT.7.V.1.d Demonstrate that there are many ways to classify things.

  • UT.7.V.2. Use and develop a simple classification system.


    • UT.7.V.2.a Using a provided classification scheme, classify things (e.g., shells, leaves, rocks, bones, fossils, weather, clouds, stars, planets).

    • UT.7.V.2.b Develop a classification system based on observed structural characteristics.

    • UT.7.V.2.c Generalize rules for classification.
