Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land. 2-ESS2-1
Clarification Statement: Examples of solutions 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.
Assessment Boundary: none
Constructing Explanations and Designing Solutions
Constructing explanations and designing solutions in K–2 builds on prior experiences and progresses to the use of evidence and ideas in constructing evidence-based accounts of natural phenomenon and designing solutions.
Compare multiple solutions to a problem. (2-ESS2-1)
Earth Materials and Systems
Wind and water can change the shape of the land. (2-ESS2-1)
Optimizing the Design Solution
Because there is always more than one possible solution to a problem, it is useful to compare and test designs. (secondary to 2-ESS2-1)
Stability and Change
Things may change slowly or rapidly. (2-ESS2-1)
