Strand - Writing
Cluster - Text Types and Purposes
[W.3.2] - Write informative/explanatory texts to examine a topic and convey ideas and information clearly.
[W.3.4] -
Produce writing in which the development and organization are appropriate to task, purpose, and audience. (Grade-specific expectations for writing types are defined in standards 1-3 above.)
[3.ESS.3.1] -
Evaluate the merit of a design solution that reduces the damage caused by weather.* Clarification Statement: Examples of design solutions to reduce weather-related damage could include a barrier to prevent flooding, a wind-resistant roof, and a lightning rod.
[3.LS.4.2] -
Use evidence to construct an explanation for how the variations in characteristics among individuals within the same species may provide advantages to these individuals in their survival and reproduction.
Clarification Statements: Examples can include rose bushes of the same species, one with slightly longer thorns than the other which may prevent its predation by deer, and color variation within a species that may provide advantages so one organism may be more likely to survive and therefore more likely to produce offspring; Examples of evidence could include needs and characteristics of the organisms and habitats involved.
[3.PS.2.1] -
Provide evidence to explain the effect of multiple forces, including friction, on an object. Include balanced forces that do not change the motion of the object and unbalanced forces that do change the motion of the object. Clarification Statements: Descriptions of force magnitude should be qualitative and relative; Force due to gravity is appropriate but only as a force that pulls objects down; State Assessment Boundaries: Quantitative force magnitude is not expected in state assessment; State assessment will be limited to one variable at a time: number, size, or direction of forces.
[3.PS.2.3] -
Conduct an investigation to determine the nature of the forces between two magnets based on their orientations and distance relative to each other. Clarification Statement: Focus should be on forces produced by magnetic objects that are easily manipulated.
[3.PS.2.4] -
Define a simple design problem that can be solved by using interactions between magnets.*
Clarification Statement: Examples of problems could include constructing a latch to keep a door shut and creating a device to keep two moving objects from touching each other.
