NCES.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.
NCES.3.E.1 Recognize the major components and patterns observed in the earth/moon/sun system.
NCES.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.
NCES.3.E.1.2 Recognize that changes in the length and 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.
Earth Systems, Structures and Processes
NCES.3.E.2 Compare the structures of the Earth's surface using models or three-dimensional diagrams.
NCES.3.E.2.1 Compare Earth's saltwater and freshwater features (including oceans, seas, rivers, lakes, ponds, streams, and glaciers).
NCES.3.L.1.2 Explain why skin is necessary for protection and for the body to remain healthy.
NCES.3.L.2 Understand how plants survive in their environments.
NCES.3.L.2.1 Remember the function of the following structures as it relates to the survival of plants in their environments: roots – absorb nutrients; stem – provide support; leaves – synthesize food; and flowers – attract pollinators and produce seeds for reproduction.
NCES.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 the growth and survival of many plants.
