Physical Science

Module Title	Content Correlations
Animal Habitats	Substances react chemically in characteristic ways with other substances to form new substances with different characteristic properties In most chemical reactions, energy is transferred into or out of a system The sun is major source of energy for changes on the earth's surface Predict when, how, why or if osmosis will occur in a given ecosystem under certain conditions
Human Settlements	Materials can exist in different states - solid, liquid, and gas, and can be changed from one state to another by heating or cooling (Standard Grades K-4) A substance has characteristic properties, all of which are independent of the amount of the sample Substances react chemically in characteristic ways with other substances to form new substances (compounds) with different characteristic properties Bonds formed between molecules can be cohesive or adhesive in nature The motion of an object can be described by its position, direction of motion, and speed Energy is a property of many substances and is transferred in many ways Energy can be considered to be kinetic energy, which is the energy of motion; or potential energy, which depends on relative position (Standard Grades 9-12) In most chemical reactions, energy is transferred into or out of a system
Systems	The motion of an object can be described by its position, direction of motion, and speed An object that is not being subjected to a force will continue to move at a constant speed and in a straight line If more than one force acts on an object along a straight line, then the forces will reinforce or cancel on another, depending on their direction and magnitude Gravitation is a universal force that each mass exerts on any other mass. (Standard Grades 9-12) Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection)
Communication Pathways	Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection) Electrical circuits provide a means of transferring electrical energy when heat, light, sound, and chemical changes are produced Electricity and magnetism are two aspects of a single electromagnetic force (Standard Grades 9-12) Sound and light waves have energy and can transfer energy when they interact with matter (Standard Grades 9-12) Explore the relationship between the speed of a wave and the medium through which it is traveling

 

Life Science

Module Title	Content Correlations
Animal Habitats	Living systems at all levels of organization demonstrate the complementary nature of structure and function All organisms have basic requirements that are necessary for sustaining life All organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment Behavior is one kind of response an organism can make to an internal or environmental stimulus An organism's behavior evolves through adaptation to its environment Populations of organisms can be categorized by the function they serve in an ecosystem Populations can increase at rapid rates For ecosystems, the major source of energy is sunlight The number of organisms an ecosystem can support depends on the resources available Extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient to allow its survival
Human Settlements	Not Applicable
Systems	Living systems at all levels of organization demonstrate the complementary nature of structure and function Organisms have systems for digestion, respiration, reproduction, circulation, excretion, movement, control, and coordination, and for protection from disease
Communication Pathways	Not Applicable

 

Earth and Space Science

Module Title	Content Correlations
Animal Habitats	Living organisms have played many roles in the earth system, including affecting the composition of the atmosphere
Human Settlements	Water circulates the earth through what is known as the "water cycle"
Systems	The solar system includes the sun, nine planets and their moons, and smaller objects, such as asteroids and comets Most objects in the solar system are in regular and predictable motion. Those motions explain such phenomena as the day, the year, phases of the moon, and eclipses Gravity is a force that keeps planets in orbit around the sun and governs the rest of the motion in the solar system Seasons result from variations in the amount of the sun's energy hitting the surface, due to the tilt of the earth's rotation on its axis and the length of the day
Communication Pathways	Not Applicable

 

Science and Technology

Module Title	Content Correlations
Animal Habitats	Design a solution or product and implement the proposed design Technology provides tools for investigations, inquiry, and analysis
Human Settlements	Use technological design to solve problems Science and technology are reciprocal
Systems	Design a solution or product and implement the proposed design Science and technology are reciprocal Technology provides instruments and techniques that enable observations of objects and phenomena, as well as tools for investigations, inquiry, and analysis
Communication Pathways	Technology provides tools for investigations, inquiry, and analysis Identify appropriate problems for technological design Design a solution or product Implement a proposed design Communicate the process of technological design

 

Science in Personal and Social Perspectives

Module Title	Content Correlations
Animal Habitats	Carrying capacity is the maximum number of individuals that can be supported in a given environment (Standard Grades 9-12) Many factors influence environmental quality (Standard Grades 9-12) Humans have the capability of controlling the natural environment both naturally and through the use of technology
Human Settlements	Technology influences society through its products and processes Social needs, attitudes, and values influence the direction of technological development Human populations use resources in the environment in order to maintain and improve their existence (Standard Grades 9-12) The earth does not have infinite resources; increasing human consumption places severe stress on the natural processes that renew some resources, and it depletes those resources that cannot be renewed (Standard Grades 9-12) Many factors influence environmental quality (Standard Grades 9-12)
Systems	Technology influences the quality of life and the ways people act and interact
Communication Pathways	Not Applicable
