Earth’s Systems: Processes that Shape the Earth

Performance Expectations:   

  • 2-ESS1-1 Use information from several sources to provide evidence that Earth events can occur quickly or slowly.
  • 2-ESS2-1  Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.
  • 2-ESS2-2  Develop a model to represent the shapes and kinds of land and bodies of water in an area. 
  • 2-ESS2-3  Obtain information to identify where water is found on Earth and that it can be solid or liquid.

Engineering Design (K-2)

Performance Expectations:   

  • K-2-ETS1-1 Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
  • K-2-ETS1-2 Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
  • K-2-ETS1-3 Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.

  • Engineering Design (K-2)

Interdependent Relationships in Ecosystems

Performance Expectations:  

  • 2-LS2-1 Plan and conduct an investigation to determine if plants need sunlight and water to grow.
  • 2-LS2-2 Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.
  • 2-LS4-1 Make observations of plants and animals to compare the diversity of life in different habitats.

  • Interdependent Relationships in Ecosystems

Structure and Properties of Matter

Performance Expectations: 

  • 2-PS1-1 Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
  • 2-PS1-2  Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.
  • 2-PS1-3  Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object. 
  • 2-PS1-4  Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
