General science

• Science: Body of knowledge, a study that is concerned with facts and principles
• Independent Variable: variable changed by the experimenter
• Dependent Variable: variable that responds to the variable that is changed in the experiment.
• Experimental group: groups that receive treatment.
• Control group: opposite of Experimental.
• Scientific law: a description of a natural occurrence that has been observed many times.
• Scientific theory: a reasonable explanation of a scientific law
• Model: helps visualize occurrences and objects that cannot be observed directly.
• Physics: the study of matter and energy and the interaction between them
• Chemistry: deals with the composition, properties, reaction and the structure of matter
• Astronomy: the study of the universe beyond the earth’s atmosphere
• Geology: the science of the origin, history and structure of the earth
• Oceanography: the exploration and study of the ocean
• Planetology: the forms of life that existed in prehistoric
• Meteorology: science that deals with the atmosphere, such as weather and climate
• Botany: the study of plants
• Zoology: the science that covers animals and animals life
• Genetics: the study of heredity
• Medicine: the science of diagnosing, treating, and preventing illness
• Fahrenheit: is a scale bases on 32 for the freezing and 212 for the boiling point
• Celsius: scale based on 0 for the freezing point and 100 for the boiling point
• Kelvin: scale is the base unit that thermodynamic temperature measurement in the international system
• Conduction: The molecules in a material are always moving.
• Convection: The movement of a gas or liquid brought about by temperature differences creates a convection current.
• Radiation: Heat transfer w/o the involvement of a physical substance in the transmission
• Volume: refers to the space that an object occupies
• Solid: is one having length, width, and thickness or height
• Liquid: measured in the cubic meter
• Density: is the mass of the object per unit volume
• Force: Anything that change the speed and direction of the moving objects
• Gravitational force: is a downward force that the watch exerts on objects
• Inertia: an object to remain at rest unless disturbed by a force
• Friction: the relative siding movement of two surfaces
• Centripetal: drive a thing inward toward a center or rotation
• Nuclear Force: the strongest known force which holds together the protons and neutrons in the nucleus of an atom.
• Electromagnetic Force: binds electrons to the atomic nucleus, atoms in the molecules, ions in solid matter, and molecules into liquids and solids.
• Matter: a general term applied to anything that has the property of occupying space and the attributes of gravity and inertia.
• Plasma is the collection of charged gaseous particles containing nearly equal numbers of negative and positive ions that are sometimes called the fourth state of matter.
• Solid is characterized by resistance to any change in shape, caused by a strong attraction between the molecules of which it is composed.
• Liquids have sufficient molecular attraction to resist forces tending to change their volume.
