Matter and Energy
Forces and Motion
100
living things that make their own food
Producers
100
takes in oxygen from the air we breathe; involves the nose/mouth, the trachea, the lungs, and the diaphragm
Respiratory System
100
used to measure wind speed and direction
Wind Vane and Anemometer
100
liquid water is heated by the sun's energy and changes from a liquid to a gas
Evaporation
100
a change in an object's position
Motion
200
living things that get energy by eating
Consumers
200
breaks down food so it can be used by the body; involves the mouth, the esophagus, the stomach, the small intestine, and the large intestine
Digestive System
200
used to measure air pressure (the weight of the air)
Barometer
200
water vapor cools and turns into liquid water, forming a cloud
Condensation
200
a measure of how far an object moves in a certain amount of time
Speed
300
a living thing that gets energy by breaking down wasts and dead plants and animals
Decomposer
300
carries oxygen, food, and wastes throughout the body; involves the heart, blood vessels, and blood
Circulatory System
300
a large body of air with about the same temperature and humidity, or moisture, throughout
Air Mass
300
a feature of matter that can be observed or measured
Physical Property
300
a push or pull on an object
Force
400
several food chains that connect
Food Web
400
the basic framework of the body; made of bones
Skeletal System
400
cold air mass bumps against a warm air mass, bringing strong storms
Cold Front
400
a property of matter that cannot be observed without changing the matter into something else
Chemical Property
400
how much matter makes up an object
Mass
500
a model that shows how the amount of energy changes as energy moves through a food chain or food web
Energy Pyramid
500
made of the muscles attached to bones that create movement
Muscular System
500
two air masses meet and stop moving; brings clouds and precipitation that often lasts several days
Stationary Front
500
the transfer of heat through things that are touching
Conduction
500
a force that acts against motion; causes objects to move slower and eventually stop moving
Friction
