L.5: Life Science
L.5.3: Ecology and Interdependence
1.1.1: All organisms need energy to live and grow. Energy is obtained from the sun. Cells transform the energy that organisms need to perform essential life functions through a complex sequence of reactions in which chemical energy is transferred from one system of interacting molecules to another.
1.1.2: A major role an organism serves in an ecosystem can be described by the way in which it obtains its energy. Energy is transferred within an ecosystem by producers, consumers, or decomposers. A healthy ecosystem is one in which diverse populations of life forms can meet their needs in a relatively stable web of life.
P.5: Physical Science
P.5.5: Organization of Matter and Chemical Interactions
13.1.1: Matter can be segregated into tiny particles that are too small to see but can be detected by other methods. These tiny particles are referred to as atoms, which can be combined to form molecules. Substances exhibit specific properties that can be observed and measured.
13.1.2: Substances of the same type can be classified by their similar observable properties. Substances can be combined in a variety of ways. A mixture is formed when two or more kinds of matter are physically combined. Solutions are a special type of mixture in which one substance is distributed evenly into another substance. When the physical properties of the components in a mixture are not changed, they can be separated in different physical ways.
13.1.3: Physical properties can be observed and measured without changing the composition of matter. A physical change occurs when the matter’s physical appearance is altered while leaving the composition of the matter unchanged. When two or more substances are mixed, a new substance with different properties can sometimes be formed, but the total amount (i.e., mass) of the substances is conserved (i.e., total mass stays the same). In a chemical change, the chemical composition of the original matter is altered to create a new substance. A different compound is present at the completion of the chemical change.
P.5.6: Motions, Forces, and Energy
13.2.1: Gravity is a force that draws objects to Earth. This force acting on an object near Earth's surface pulls that object toward the planet's center. The motion of an object can be described in terms of its position, direction, and speed. Multiple factors determine the rate and motion of an object. Other than Earth, any celestial object will exert varying gravitational pulls on other objects according to their mass and density.
E.5: Earth and Space Science
E.5.8: Earth and the Universe
42.1.1: Astronomy is the study of celestial objects in our solar system and beyond. A solar system includes one or more suns (stars) and all other objects orbiting in that system. Planets in our night sky change positions and are not always visible from Earth as they orbit our sun. Stars that can be seen in the night sky lie beyond our solar system and appear in patterns called constellations. Constellations can be used for navigation and appear to move together across the sky because of Earth’s rotation and revolution around the sun.
42.1.2: Earth orbits around the sun as the moon orbits around Earth. The revolution and rotation of Earth on a tilted axis provide evidence of patterns that can be observed, studied, and predicted.
E.5.10: Earth’s Resources
42.2.1: Human activities can impact natural processes and availability of resources. To reduce impacts on the environment (including humans), various best practices can be used. New and improved conservation practices are constantly being developed and tested.
