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

Make observations of plants and animals to compare the diversity of life in different habitats.

2-ESS1 Earth's Place in the Universe

Use information from several sources to provide evidence that Earth events can occur quickly or slowly.

2-ESS2 Earth's Systems

Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.

Develop a model to represent the shapes and kinds of land and bodies of water in an area.

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.
