2nd Grade
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.
