3-PS2 Motion and Stability: Forces and Interactions


    3-PS2-1:  Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.

    3-PS2-2:  Make observations and/or measurements of an object’s motion to provide evidence that that a pattern can be used to predict future motion.

    3-PS2-3:  Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each    other.

    3-PS2-4:  Define a simple design problem that can be solved by applying scientific ideas about magnets.

3-LS1 From Molecules to Organisms: Structures and Processes


    3-LS1-1:  Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.

3-LS2 Ecosystems: Interactions, Energy, and Dynamics


    3-LS2-1:  Construct an argument that some animals form groups that help members survive.

3-LS3 Heredity: Inheritance and Variation of Traits


    3-LS3-1:  Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms. 

    3-LS3-2:  Use evidence to support the explanation that traits can be influenced by the environment.

3-LS4 Biological Evolution: Unity and Diversity


    3-LS4-1:  Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.

    3-LS4-2:  Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.

    3-LS4-3:  Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.

    3-LS4-4:  Make a claim about the merit of a solution to a problem caused when the environment changes and the types of plants and animals that live there may change. 

3-ESS2 Earth's Systems


    3-ESS2-1:  Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.

    3-ESS2-2:  Obtain and combine information to describe climates in different regions of the world.

3-ESS3 Earth and Human Activity


    3-ESS3-1:  Make a claim about the merit of a design solution that reduces the impacts of a weather-related hazard.

3-5-ETS1 Engineering Design


    3-5-ETS1-1:  Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

    3-5-ETS1-2:  Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

    3-5-ETS1-3:  Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
