Structure and Properties of Matter

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.
- Compare properties of materials (2-A.3)
- Identify materials in objects (2-A.4)
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.
- Identify multiple materials in objects (2-A.5)
2-PS1-4 Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.

Interdependent Relationships in Ecosystems

2-LS2-1 Plan and conduct an investigation to determine if plants need sunlight and water to grow.
- Classify fruits and vegetables as plant parts (2-K.1)
- Identify plant parts and their functions (2-K.2)
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.

Earth's Systems: Processes that Shape the Earth

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.
- Changes to Earth's surface: erosion (2-P.5)
- Evaluate multiple design solutions to prevent flooding (3-V.2)
2-ESS2-2 Develop a model to represent the shapes and kinds of land and bodies of water in an area.
- Water on Earth (2-O.1)
- Identify Earth’s land features (2-O.3)
2-ESS2-3 Obtain information to identify where water is found on Earth and that it can be solid or liquid.
- Bodies of water (2-O.)
- Water on Earth (2-O.1)

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.
- Evaluate multiple design solutions to prevent flooding (3-V.2)
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.
- Identify the best design solution to prevent hurricane damage (3-V.3)
