[2.ESS.2.1] - Investigate and compare the effectiveness of multiple solutions designed to slow or prevent wind or water from changing the shape of the land.* Clarification Statements: Solutions to be compared could include different designs of dikes and windbreaks to hold back wind and water, and different designs for using shrubs, grass, and trees to hold back the land; Solutions can be generated or provided.

Predecessor Standards:

  • K.MD.A.1
    Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
  • K.MD.A.2
    Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

Successor Standards:

  • 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.

Same Level Standards:

  • 2.MD.A.4
    Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
  • 2.ESS.2.2
    Map the shapes and types of landforms and bodies of water in an area. Clarification Statements: Examples of types of landforms can include hills, valleys, river banks, and dunes; Examples of water bodies can include streams, ponds, bays, and rivers; Quantitative scaling in models or contour mapping is not expected.
  • 2.ESS.2.4
    Observe how blowing wind and flowing water can move Earth materials from one place to another and change the shape of a landform. Clarification Statement: Examples of types of landforms can include hills, valleys, river banks, and dunes.
  • 2.ETS.1.3
    Analyze data from tests of two objects designed to solve the same design problem to compare the strengths and weaknesses of how each object performs.* Clarification Statements: Data can include observations and be either qualitative or quantitative; Examples can include how different objects insulate cold water or how different types of grocery bags perform.
