Clarification Statement - S.K.LS.1.1.CS:
Examples of patterns could include that animals need to take in food but plants do not; the different kinds of food needed by different types of animals; the requirement of plants to have light; and, that all living things need water.

Science and Engineering Practices - PK2.SEP4.2:
Use observations (firsthand or from media) to describe patterns in the natural world in order to answer scientific questions.

Disciplinary Core Ideas - S.K.LS.1.1.DCI:
LS1.C: Organization for Matter and Energy Flow in Organisms •(NYSED) All animals need food, air, and water in order to live, grow, and thrive. Animals obtain food from plants or from other animals. Plants need water, air, and light to live, grow, and thrive.

Crosscutting Concepts - CC1.1:
Patterns in the natural and human designed world can be observed and used as evidence.

Clarification Statement - S.K.ESS.2.2.CS:
Examples of plants and animals changing their environment could includema squirrel digs in the ground to hide its food and tree roots can break concrete.

Science and Engineering Practices - PK2.SEP7.1:
Construct an argument with evidence to support a claim.

Disciplinary Core Ideas - S.K.ESS.2.2.DCI:
ESS2.E: Biogeology •Plants and animals can change their environment. ESS3.C: Human Impacts on Earth Systems •Things that people do to live comfortably can affect the world around them. But they can make choices that reduce their impacts on the land, water, air, and other living things. (secondary to K-ESS2-2)

Crosscutting Concepts - CC3.1:
Systems in the natural and designed world have parts that work together.

Clarification Statement - S.K.ESS.3.1.CS:
Examples of relationships could include that deer eat buds and leaves, therefore, they usually live in forested areas, and grasses need sunlight so they often grow in meadows. Plants, animals, and their surroundings make up a system.

Science and Engineering Practices - PK2.SEP2.3:
Use a model to represent relationships in the natural world.

Disciplinary Core Ideas - S.K.ESS.3.1.DCI:
ESS3.A: Natural Resources •Living things need water, air, and resources from the land, and they live in places that have the things they need. Humans use natural resources for everything they do.

Crosscutting Concepts - CC3.1:
Systems in the natural and designed world have parts that work together.

Clarification Statement - S.K.ESS.3.3.CS:
Examples of human impact on the environment (land, water, air, plants, and animals) could include cutting trees to produce paper and using resources to produce bottles. Examples of solutions could include reusing paper and recycling cans and bottles.

Science and Engineering Practices - PK2.SEP8.1:
Communicate solutions with others in oral and/or written forms using models and/or drawings that provide detail about scientific ideas.

Disciplinary Core Ideas - S.K.ESS.3.3.DCI:
ESS3.C: Human Impacts on Earth Systems •Things that people do to live comfortably can affect the world around them. But they can make choices that reduce their impacts on the land, water, air, and other living things. ETS1.B: Developing Possible Solutions •Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem’s solutions to other people. (secondary to K-ESS3-3)

Crosscutting Concepts - CC2.2:
Events have causes that generate observable patterns.
