3.L.1- Understand 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 system. 

• 3.L.1.2- Explain why skin is necessary for protection and for the body to remain healthy.

3.L.2- Understand how plants survive in their environments.

• 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; Stems – provide support; Leaves – synthesize food; Flowers – attract pollinators and produce seeds 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 the growth and survival of many plants.

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 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.
