EALR 1: Systems.  Big Idea: Systems (SYS).  Core Content:  Part-Whole Relationships
 
   
  • In grades K-1, students gain fluency in using the concept of part-whole relationships. They agree on names for the parts that make up several types of whole objects, including plants and animals. They learn that objects can be easily taken apart and put back together again, while other objects cannot be taken apart and reassembled without damaging them. Removing one or more parts will usually change how the object functions. Fluency with the part-whole relationship is essential for all of the sciences and is an important building block for more sophisticated understanding of how systems operate in natural and designed environments.
 
 
EALR 2: Inquiry.  Big Idea: Inquiry (INQ).  Core Content:  Making Observations
 
   
  • Students learn that scientific investigations involve trying to answer questions by making observations or trying things out, rather than just asking an adult. Children are naturally curious about nearly everything—butterflies and clouds, and why the Moon seems to follow them at night. The essence of this standard is to channel students' natural curiosity about the world, so that they become better questioners, observers, and thinkers, laying the groundwork for increasing understanding and abilities in science inquiry in the years to come.
 
 
EALR 3: Application.  Big Idea: Application (APP).  Core Content:  Tools and Materials
 
   
  • Students learn to use simple tools (e.g., pencils, scissors) and materials (e.g., paper, tape, glue, and cardboard) to solve problems in creative ways. Though students have a natural inclination to use tools and materials to make things, guidance is required to channel these interests into solving a practical problem. Although students are not expected to make a distinction between science and technology at this age, they can and should develop the idea that tools and materials can be used to solve problems, and that many problems can have more than one solution.
 
 
EALR 4 PS1: Physical Science.  Big Idea: Force and Motion (PS1).  Core Content:  Push-Pull and Position
 
   
  • Students learn how to describe the position and motion of objects and the effects of forces on objects. Students start by describing the position of one object with respect to another object (e.g., in front, behind, above, and below) and then describe motion as a change in position. Forces are introduced as pushes and pulls that can change the motion of objects, and students learn through observation that various forces act through contact while others act from a distance (without touching the object). These basic concepts about forces and motion provide a foundation for learning to quantify motion in later years.
 
 
EALR 4 PS2: Physical Science.  Big Idea: Matter: Properties and Change (PS2).  Core Content:  Liquids and Solids
 
   
  • Students learn about the properties of liquids and solids. When a liquid is poured into a container, it takes the shape of the part of the container that it occupies. Cooling a liquid can turn the liquid into a solid (e.g., water to ice). When it becomes a solid it assumes the shape of the container and retains that shape, even when removed from the container. These observations about the properties of materials and how numerous materials can change from liquid to solid and back again begin to build an understanding of matter and its transformations that will be formalized as states of matter during the grade 2-3 band.
 
 
EALR 4 PS3: Physical Science.  Big Idea: Energy: Transfer; Transformation and Conservation (PS3).  Core Content:  None
 
   
  • No standards for K-1 Energy: Transfer; Transformation and Conservation because the content is not developmentally appropriate for students in this grade band.
 
 
EALR 4 ES1: Earth and Space Science.  Big Idea: Earth in Space (ES1).  Core Content:  Observing the Sun and Moon
 
   
  • Students learn that objects they see in the sky, such as clouds and birds, change from minute to minute, while other things, such as apparent movement of the Sun and Moon, follow patterns if observed carefully over time. The Moon can sometimes be seen during the day and sometimes at night, and its shape appears to change gradually during the month. The study of the sky can help young children realize that they can find patterns in the world through their own observations.
 
 
EALR 4 ES2: Earth and Space Science.  Big Idea: Earth Systems Structures and Processes (ES2).  Core Content:  Properties and Change
 
   
  • Students learn about Earth materials through their own observations. They learn to distinguish between natural materials and those that have been changed by people. They study natural substances such as rocks and soil, and find that these Earth materials are made up of smaller parts and different components. They learn to use common terms, such as hard, soft, dry, wet, heavy, and light, to describe what they see. These observations help students become familiar with the materials in the world around them in terms of properties and to think about how people use natural materials in various ways.
 
 
EALR 4 ES3: Earth and Space Science.  Big Idea: Earth History (ES3).  Core Content:  None
 
   
  • No standards for K-1 Earth History because the content is not developmentally appropriate for students in this grade band.
 
 
EALR 4 LS1: Life Science.  Big Idea: Structures and Functions of Living Organisms (LS1).  Core Content:  Plant and Animal Parts
 
   
  • Students learn that all living things have basic needs, and they meet those needs in various ways. Just as humans have external body parts that perform different functions to meet their needs, animals and plants also have body parts that perform different functions to meet their needs. A magnifier is a tool that reveals further details of plant and animal parts that are not easily seen with the unaided eye. Learning about the diverse needs of plants and animals and the various ways they meet their needs will help to prepare students to understand more detailed structures beginning at the 2-3 grade band.
 
 
EALR 4 LS2: Life Science.  Big Idea: Ecosystems (LS2).  Core Content:  Habitats
 
   
  • Students learn that all plants and animals live in and depend on habitats. Earth has many different habitats, and these different habitats support the life of many different plants and animals, including humans. People have the ability to make rapid changes in natural habitats and to keep a habitat healthy so that living conditions can be maintained.
 
 
EALR 4 LS3: Life Science.  Big Idea: Biological Evolution (LS3).  Core Content:  Classifying Plants and Animals
 
   
  • Students learn that some objects are alive and others are not, and that many living things are classified as either plants or animals based on observable features and behaviors. Plants and animals are further classified into smaller groups such as insects and trees. Even these groups can be further subdivided. Classification provides a way to organize and find patterns in the amazing diversity of plants, animals, and the nonliving environment.
