air pressure
the weight of the atmosphere pressing at a certain place
· Circulatory System
the body system that carries oxygen, food, and wastes throughout the body
balanced forces
when two equal forces are applied to an object in opposite directions (no
movement)
conductor
a material through which heat can move easily
condensation
the change from a gas to a liquid
atmosphere
the mixture of gases and dust that surround the Earth
Digestive System
the body system that breaks down food so it can be used by the body
friction
a force that acts between surfaces that touch each other
cooling
temperature drop caused by thermal energy moving from a warmer object to a cooler
object causing a drop-in temperature as the flow continues till the materials reach the same
temperature
evaporation
the change from a liquid to a gas
barometer
a tool used to measure air pressure
esophagus
the tube or pipe that connects the mouth to the stomach
gravity
a force that pulls objects toward each other
heating –

energy transfer
movement of energy from one source to another

muscles
organs composed of tissue, fibers or cells that contract (pull, shorten) to produce a
particular movement
weight
the measure of the of gravity on an object mass
conservation

insulator
a material through which heat does not move easily
Gulf Stream
a warm WATER current that flows from the south to the north along the east coast
of the United States and then farther out to the Atlantic Ocean. This flow of warm water along the
east coast makes the temperature milder by warming the land and air during cooler months
brain

nervous system
inertia
an objects resistance to a change in motion
