100
A ____ _____ shows how each living thing gets its food. A ____ _____ always starts with plant life and ends with an animal.
Food Chain
100
Evidence of the existence of an organism from the past, such as the skeleton of a dinosaur, or the imprint of an extinct plant. _______ are remnants of an organism preserved in the Earth's crust.
Fossils
100
A form of energy that can produce light, heat, and magnetism.
Electricity
100
A piece of metal whose atoms are arranged so that they line up with two 'poles,' one positive (+) and one negative (-).
Magnet
100
In the water cycle, this is the fall of water, ice, or snow onto the surface of the Earth.
Precipitation
200
The whole group of interacting food chains in an ecological community.
Food Web
200
An indentation or mark from an object that has been pressed into a surface, or formed in sediments over time.
Imprint
200
Fill in the blanks. A _________ is a material that allows electricity or heat to travel through it easily. An _________ is a material that does not allow electrical charges to move or flow freely.
Conductor Insulator
200
An invisible force that can cause a magnet to be pulled toward a piece of iron, some other metals, and other magnets.
Magnetism
200
The process of changing a liquid to a gas below the liquid's boiling point. Also, the part of the water cycle in which water from rivers, lakes, and streams becomes water vapor in the atmosphere
Evaporation
300
A living thing that makes its own food.
Producer
300
What type of fossils include the remains of organisms that were once living.
Body Fossils
300
An unbroken path between a source of electricity (like a battery) conductive wires and a resistor (like a light bulb).
Circuit
300
To cause to move closer. Example: When the unlike poles of two magnets are brought together ("opposites _______"). The positive (+) pole of one magnet will "stick to" the negative (-) pole of another magnet.
Attract
300
The change of a substance from a gaseous state to a liquid state. For instance, water vapor in the air changes to droplets of water when the temperature of the vapor is lowered.
Condensation
400
An organism that gets its food by eating other organisms.
Consumer
400
These fossils are the signs that organisms were once present.
Trace Fossils
400
A circuit without interruption, making a continuous path so that electricity can flow.
Closed Circuit
400
To present an opposing force to; push back or away by a force. Example: When the like poles of two magnets are brought together. The like poles will be difficult to push together, and will spring apart if let go.
Repel, Repulsion, or Magnetic Repulsion
400
The part of the water cycle in which water soaks into the ground.
Percolation
500
Fill in all 3 blanks to get this question correct. A _________ eats only meat. An _________ eats only plants. An ________ eats both plants and animals.
Carnivore Herbivore Omnivore
500
Most Fossils are found in this type of rock.
Sedimentary
500
The flow of electricity through a conductor.
Current
500
A type of magnet in which the magnetic field is produced by the flow of electric current
Electromagnet
500
Condition or stage of the physical makeup of something. Examples: Solid, Liquid, and Gas
