2-PS1 Matter and Its Interactions


    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.

2-LS2 Ecosystems: Interactions, Energy, and Dynamics


    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 Biological Evolution: Unity and Diversity


    2-LS4-1:  
Make observations of plants and animals to compare the diversity of life in different habitats.

2-ESS1 Earth's Place in the Universe


    2-ESS1-1:  
Use information from several sources to provide evidence that Earth events can occur quickly or slowly.

2-ESS2 Earth's Systems


    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.

K-2-ETS1 Engineering Design


    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.
