5th Grade Science

Physical Science

• Matter exists as particles that are too small to be seen; measurements of a variety of observable properties can be used to identify particular materials.

• Chemical Reactions that occur when substances are mixed can be identified by the emergence of substances with different properties; the total mass remains the same.

• The gravitational force of Earth acting on an object near Earth’s surface pulls that object toward the planet’s center.

• The energy released from food was once energy from the sun.

Life Science

• Plants acquire their material from growth chiefly from air and water.

• Matter cycles between air and soil and among plants, animals and microbes as these organisms live and die.

Earth and Space

• Stars range greatly in size and distance from Earth, and this can explain their relative brightness.

• Earth’s orbit and rotation and the orbit of the moon around earth cause observable patterns.

• Earth’s major systems interact in multiple ways to affect Earth’s surface materials and processes.

• Most of Earth’s water is in the ocean and much of Earth’s freshwater in glaciers or underground.

• Societal activities have had major effects on land, ocean, atmosphere and even outer space.
