6th Grade Cards: Science

the maximum displacement of a periodic wave; greatness of magnitude

the mass of air surrounding the Earth; a particular environment or surrounding influence; the weather or climate at some place

the smallest possible amount of matter which still retains its identity as a chemical element, now known to consist of a nucleus surrounded by electrons.

hold or carry in equilibrium

the regions of the surface and atmosphere of the Earth (or other planet) where living organisms exist

the minute elementary structures, of which the greater part of the various tissues and organs of animals and plants are composed

the relation between two different kinds of organisms when one receives benefits from the other without damaging it

the fundamental principle of physics that the total energy of an isolated system is constant despite internal changes

a variable in a logical or mathematical expression whose value depends on the independent variable

a flow of electricity through a conductor

energy made available by the flow of electric charge through a conductor

a temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet

the entire range of wavelengths of all known electromagnetic radiations extending from gamma rays through visible light, infrared, and radio waves, to X-rays

graphical representation used for showing the biomass or productivity at each tropical level in a given ecosystem

the process of changing one form of energy to another

a community of organisms where there are several interrelated food chains

in the context of physical sciences, identify energy as forms as Kinetic, Potential, and more.

the solid part of the earth consisting of the crust and outer mantle

watery layer of the earth's surface

a variable whose values are independent of changes in the values of other variables

the lines of force surrounding a permanent magnet or a moving charged particle

the relation between two different species of organisms that are interdependent; each gains benefits from the other

the relation between two different kinds of organisms in which one receives benefits from the other by causing damage to it (usually not fatal damage)

image of something as reflected by mirror; remark expressing careful consideration

turning or bending of any wave, such as light or sound wave, when it passes from one medium into another of different optical density

the age of a rock or formation given relative to other rocks or formation, usually defined as a zone fossil name

rock formed from consolidated clay sediments

application of science, especially to industrial or commercial objectives

tension is the pulling force exerted by a string, cable, chain, or similar solid object on another object

a movement up and down or back and forth; something that rises rapidly

the distance from a point or phase in a wave to the nearest point at which the same phase occurs
