MS-LS1 From Molecules to Organisms: Structures and Processes

    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. 

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

    MS-LS1-4:  Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

    MS-LS1-5:  Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms. 

    MS-LS1-6:  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.

    MS-LS1-7:  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. 

    MS-LS1-8:  Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.

MS-LS2 Ecosystems: Interactions, Energy, and Dynamics

    MS-LS2-4:  Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

    MS-LS2-5:  Evaluate competing design solutions for maintaining biodiversity and ecosystem services.

MS-LS3 Heredity: Inheritance and Variation of Traits

    MS-LS3-1:  Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

    MS-LS3-2:  Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.

MS-LS4 Biological Evolution: Unity and Diversity

    MS-LS4-3:  Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy. 

    MS-LS4-4:  Construct an explanation based on evidence that describes how genetic variations of traits in a population increasesome individuals’ probability of surviving and reproducing in a specific environment.

    MS-LS-4-5:  Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms. 

    MS-LS4-6:  Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.

MS-ESS2 Earth's Systems

    MS-ESS2-4:  Develop a model to describe the cycling of water through Earth's systems driven by energy from the sun and the force of gravity.

MS-ESS3 Earth and Human Activity

    MS-ESS3-3:  Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

    MS-ESS3-4:  Construct an argument supported by evidence for how increases in human population and per-capital consumption of natural resources impact Earth's systems.

MS-ETS1 Engineering Design

    MS-ETS1-1:  Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

    MS-ETS1-2:  Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

    MS-ETS1-3:  Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

    MS-ETS1-4:  Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
