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)
ESS2.A: Earth Materials and Systems Wind and water can change the shape of the land. (2-ESS2-1) ETS1.C: 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) Connections to Engineering, Technology, and Applications of Science Influence of Science, Engineering, and Technology on Society and the Natural World Developing and using technology has impacts on the natural world. (2-ESS2-1) Connections to Nature of Science Science Addresses Questions About the Natural and Material World Scientists study the natural and material world. (2-ESS2-1)
