IL Science Standards (Grade 2) | Free Standards Reference

📌 Biological Evolution: Unity and Diversity (2-LS4) 1 standard

2-LS4-1

Compare diversity of life across habitats

Make observations of plants and animals to compare the diversity of life in different habitats. [Clarification Statement: Emphasis is on the diversity of living things in each of a variety of different habitats.] [Assessment Boundary: Assessment does not include specific animal and plant names in specific habitats.]

📌 Earth's Place in the Universe (2-ESS1) 1 standard

2-ESS1-1

Show evidence Earth events occur quickly or slowly

Use information from several sources to provide evidence that Earth events can occur quickly or slowly. [Clarification Statement: Examples of events and timescales could include volcanic explosions and earthquakes, which happen quickly and erosion of rocks, which occurs slowly.] [Assessment Boundary: Assessment does not include quantitative measurements of timescales.]

📌 Earth's Systems (2-ESS2) 3 standards

2-ESS2-1

Compare solutions to slow land/water erosion

Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.* [Clarification Statement: Examples of solutions could include different designs of dikes and windbreaks to hold back wind and water, and different designs for using shrubs, grass, and trees to hold back the land.]

2-ESS2-2

Model shapes of land and bodies of water

Develop a model to represent the shapes and kinds of land and bodies of water in an area. [Assessment Boundary: Assessment does not include quantitative scaling in models.]

2-ESS2-3

Identify where water is found on Earth

Obtain information to identify where water is found on Earth and that it can be solid or liquid.

📌 Ecosystems: Interactions, Energy, and Dynamics (2-LS2) 2 standards

2-LS2-1

Investigate plants' need for sunlight and water

Plan and conduct an investigation to determine if plants need sunlight and water to grow. [Assessment Boundary: Assessment is limited to testing one variable at a time.]

2-LS2-2

Model how animals disperse seeds or pollinate

Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.*

📌 Engineering Design (K-2-ETS1) 3 standards

K-2-ETS1-1

Define a simple problem to be solved by design

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

Sketch or model a design solution

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

Compare test data from two competing designs

Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.

📌 Matter and its Interactions (2-PS1) 4 standards

2-PS1-1

Classify materials by observable properties

Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. [Clarification Statement: Observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.]

2-PS1-2

Analyze material properties suited to a purpose

Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.* [Clarification Statement: Examples of properties could include, strength, flexibility, hardness, texture, and absorbency.] [Assessment Boundary: Assessment of quantitative measurements is limited to length.]

2-PS1-3

Show how objects can be disassembled and rebuilt

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. [Clarification Statement: Examples of pieces could include blocks, building bricks, or other assorted small objects.]

2-PS1-4

Argue which heating/cooling changes are reversible

Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot. [Clarification Statement: Examples of reversible changes could include materials such as water and butter at different temperatures. Examples of irreversible changes could include cooking an egg, freezing a plant leaf, and heating paper.]
