Physical Science Properties and changes of properties in matter Substances, such as metals, are often placed in categories or groups if they react in similar ways. Motions and forces 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. If more than one force acts on an object, then the forces will reinforce or cancel one another. Transfer of energy Energy is a property of many substances and is associated with heat, light, electricity, and mechanical motion.
Energy is transferred in many ways.
Electrical circuits provide a means of transferring electrical energy when heat, light, sound, and chemical changes are produced. Life Science Regulation and behavior Behavior is one kind of response an organism can make to an internal or environmental stimulus. Behavioral response is a set of actions determined in part by heredity and in part from experience. Science and Technology Abilities of technological design Implement a proposed solution. Evaluate completed technological designs or products.
