North Carolina Essential Standards
3.L.1 Understand the human body systems and how they are essential for life: protection, movement, and support.
3.L.1.1 Compare the different functions of the skeletal and muscular systems.
3.L.1.2 Explain why skin is necessary for protection and for the body to remain healthy.
3.P.1 Understand motion and factors that affect motion.
3.P.1.1 Infer changes in speed or direction resulting from forces acting on an object
3.P.1.2 Compare the relative speeds (faster or slower) of objects that travel the same distance in different amounts of time.
3.P.1.3 Explain the effects of earth's gravity on the motion of any object on or near the earth.
2.P.2 Understand properties of solids and liquids and the changes they undergo.
2.P.2.1 Give examples of matter that change from a solid to a liquid and from a liquid to a solid by heating and cooling.
2.P.2.2 Compare the amount (volume and weight) of water in a container before and after freezing.
2.P.2.3 Compare what happens to water left in an open container over time as to water left in a closed container.
3.P.2 Understand the structure and properties of matter before and after they undergo a change.
3.P.2.2 Compare solids, liquids, and gases based on their basic properties.
3.P.2.3 Summarize changes that occur to the observable properties of materials when different degrees of heat are applied to them, such as melting ice or ice cream, boiling water or an egg, or freezing water.
3.P.3 Recognize how energy can be transferred from one object to another.
3.P.3.1 Recognize that energy can be transferred from one object to another by rubbing them against each other.
3.P.3.2 Recognize that energy can be transferred from a warmer object to a cooler one by contact or at a distance and the cooler object gets.
3.L.2 Understand how plants survive in their environments.
3.L.2.1 Remember the function of the following plant structures as it relates to the survival of plants in their environment:
· Roots -absorb nutrients
· Stems -provide support
· Leaves - synthesize food
· Flowers - attract pollinators and produce seed for reproduction
3.L.2.2 Explain how environmental conditions determine how well plants survive and grow.
3.L.2.3 Summarize the distinct stages of the life cycle of seed plants.
3.L.2.4 Explain how the basic properties (texture and capacity to hold water) and components (sand, clay and humus) of soil determine the ability of soil to support growth and survival of many plants
4.L.1 Understand the effects of environmental changes, adaptations and behaviors that enable animals (including humans) to survive in changing habitats.
4.L.1.3 Explain how humans can adapt their behavior to live in changing habitats (e.g., recycling wastes, establishing rain gardens, planting trees and shrubs to prevent flooding and erosion).
Sun, Moon, Stars and Earth
3.E.1 Recognize the major components and patterns observed in the earth/moon/sun system.
3.E.1.1 Recognize that the earth is part of a system called the solar system that includes the sun (a star), planets, and many moons and the Earth is the third planet from the sun in our solar system.
3.E.1.2 Recognize the changes in the length or direction of an object's shadow indicate the apparent changing position of the sun during the day although the patterns of the stars in the sky, to include the sun, stay the same.
3.E.2 Compare the structures of the Earth's surface using models or three-dimensional diagrams.
3.E.2.1 Compare Earth's saltwater and freshwater features (including oceans, seas, rivers, lakes, ponds, streams, and glaciers).
3.E.2.2 Compare Earth's land features (including volcanoes, mountains, valleys, canyons, caverns, and islands) by using models, pictures, diagrams, and maps.
4.P.3 Recognize that energy takes various forms that may be grouped based on their interaction with matter.
4.P.3.2 Recognize that light travels in a straight line until it strikes an object or travels from one medium to another, and that light can be reflected, refracted, and absorbed.
