3rd grade imageIn third grade, students are expected to demonstrate grade-appropriate proficiency in asking questions and defining problems; developing and using models, planning and carrying out investigations, analyzing and interpreting data, constructing explanations and designing solutions, engaging in argument from evidence, and obtaining, evaluating, and communicating information. Students are expected to use these practices to demonstrate understanding of the core ideas.


[PS2] Motion and Stability: Forces and Interactions

    • SCI-03.PS2.01  Plan and conduct an investigation to prove the effects of balanced and unbalanced forces on the motion of an object.
    • SCI-03.PS2.02  Make observations and metric measurements of an object's motion to prove that a pattern can be used to predict future motion
    • SCI-03.PS2.03  Ask questions to determine cause and effect relationships of static electricity or magnetic interactions between two objects not in contact with each other.
    • SCI-03.PS2.04  Define a simple design problem that can be solved by applying scientific ideas about magnets.



[LS1] From Molecules to Organisms: Structures and Processes

    • SCI-03.LS1.01  Develop models to describe that organisms have unique and diverse life cycles but all experience birth, growth, reproduction, and death.



[LS2] Ecosystems: Interactions, Energy, and Dynamics

    • SCI-03.LS2.01  Construct an argument that some animals form groups that help members survive.



[LS3] Heredity: Inheritance and Variation of Traits

    • SCI-03.LS3.01  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.
    • SCI-03.LS3.02  Use evidence to support the explanation that the expression of traits can be influenced by the environment.



[LS4] Biological Evolution: Unity and Diversity

    • SCI-03.LS4.01  Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.
    • SCI-03.LS4.02  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.
    • SCI-03.LS4.03  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.



[ESS2] Earth's Systems

    • SCI-03.ESS2.01  Represent data in tables and graphical displays to describe and predict typical weather conditions expected during a particular season.
    • SCI-03.ESS2.02  Obtain and combine information to describe climates in different regions of the world.



[ESS3] Earth and Human Activity

    • SCI-03.ESS3.01  Evaluate the feasibility of a design solution that reduces the impacts of a weather-related hazard.



[ETS1] Grade 3-5 Engineering Design

    • SCI-EL.ETS1.01 Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
    • SCI-EL.ETS1.02 Generate and compare multiple possible so lutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
    • SCI-EL.ETS1.03 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.
