Past Due Assignments

  • Unit 1 - LS1: Molecules to Organisms: Structure and Processes

    Students who demonstrate understanding can:

    MS-LS1-1.       Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.

    • Further Explanation: Emphasis is on developing evidence that living things are made of cells, distinguishing between living and non-living cells, and understanding that living things may be made of one cell or many and varied cells.

    MS-LS1-2.       Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.

    • Further Explanation: Emphasis is on the cell functioning as a whole system and the primary role of identified parts of the cell, specifically the nucleus, chloroplasts, mitochondria, cell membrane, and cell wall. These are visible with a light microscope.
    • Content Limit: Assessment of organelle structure/function relationships is limited to the cell wall and cell membrane. Assessment of the function of the other organelles is limited to their relationship to the whole cell. Assessment does not include the biochemical function of cells or cell parts.

    MS-LS1-3.       Use argument supported by evidence for how a living organism is a system of interacting subsystems composed of groups of cells.

    • Further Explanation: Emphasis is on the conceptual understanding that cells form tissues and tissues form organs specialized for particular body functions. Examples could include the interaction of subsystems within a system and the normal functioning of those systems.
    • Content Limit: Assessment does not include the mechanism of one body system independent of others. Assessment is not focused on human body systems.

    MS-LS1-4.       Construct a scientific argument based on evidence to defend a claim of life for a specific object or organism.

    • Further Explanation: Examples should include both biotic and abiotic items, and should be defended using accepted characteristics of life.
    • Content Limit: Assessment does not include viruses, or other disputed examples.

    MS-LS1-5.       Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

    • Further Explanation: Emphasis is on tracing movement of matter and flow of energy.
    • Content Limit: Assessment does not include the biochemical mechanisms of photosynthesis.

    MS-LS1-6.       Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

    • Further Explanation: Emphasis is on describing that molecules are broken apart and put back together and that in this process, energy is released. Also understanding that the elements in the products are the same as the elements in the reactants .
    • Content Limit: Assessment does not include details of the chemical reactions for photosynthesis or respiration.
