Organism Needs
100
This is a material through which an electric charge moves freely.
What is a conductor?
100
These are things from the environment that people use to meet their needs.
What are natural resources?
100
These arew the natural features of the Earth's surface.
What is a landform?
100
This is the imaginary line that the Earth spins on.
What is an axis?
100
All organisms need food, water, air, and this to survive.
What is space or shelter?
200
This is a material through which an electric charge moves through with difficulty.
What is an insulator?
200
These are resources that can be replaced as quickly as people use them.
What are renewable resources?
200
This landform is steep on both sides and flat on the top.
What is a plateau?
200
This is the amount of the Earth that is lit by the sun at any one time.
What is one half?
200
This is the process that plants use to make their own food.
What is photosynthesis?
300
This is the type of circuit that allows energy to flow through it.
What is a closed circuit?
300
These are resources that cannot be replaced for an extremely long time.  Once you use them up, they are gone forever.
They are nonrenewable resources?
300
The carrying away of tiny bits of rock, soil, or other particles to a new location.  
What is erosion?
300
This is the amount of time it takes the Earth to rotate on its axis one time.
What is 24 hours?
300
Tiny openings in these let in carbon dioxide and let out oxygen on a plant.
What are leaves?
400
This type of circuit has two or more paths through which electricity flows.
What is a parallel Circuit?
400
What type of resource is coal?
What is a nonrenewable resource?
400
This is the laying down of particles carried away during erosion in a new location.
What is deposition?
400
This is the amount of time it takes the Earth to revolve around the sun one time.
What is 24 hours?
400
This is when animals travel great distances to find food during the winter.
What is migration?
500
This type of circuit allows electric current to flow in ONE circular path.
What is a series circuit?
500
These are the "3 Rs".
What are reduce, reuse, recycle?
500
This is the process of changing Earth's landforms caused by water (rain and waves), wind, or chemicals(such as acid).
What is weathering?
500
This is the time of day when your shadow is at its smallest. 
What is noon?
500
This is the gas found in the air that plants need to make the food they need.
What is carbon dioxide?
