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.

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.

LS4: Biological Evolution: Unity and Diversity

2-LS4-1

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

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.

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.

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.
