Babies.
Who are offsprings?
200
This stiff wall protects the cell and can only be found in plant cells.
What is a cell wall?
200
This is a structure built across a river to control its flow.
What is a dam?
200
Solid, liquid, and gas.
What are the states of matter?
200
Magnets will do this if two unlike poles come close to each other.
What is "attract"?
300
These animals are cold-blooded, live on land, covered with scales, and lay eggs.
What are reptiles?
300
This part of the cell contains its genes and controls the cell’s growth.
What is a nucleus?
300
This is a crack in the rock of Earth’s crust which can cause earthquakes.
What is a fault?
300
This is formed when two or more kinds of matter are mixed together.
What is a mixture?
300
This is a material through which electricity cannot easy flow. Examples include rubber, wood, plastic, and glass.
What are insulators?

What is an electromagnet?
500
These plants have tubes that carry water from roots to leaves to the rest of the plant.
What are vascular plants?
500
This thin layer can be found in both plant and animal cells; it allows water and nutrients to come into the cell and allows wastes to leave the cell.
What is a cell membrane?
500
This is a method created to prevent erosion, in which farmers plow across the sides of hills instead of down their slopes.
What is contour plowing?
500
Examples include rusting iron, burning paper, cooking eggs, and tarnishing silver.
What are chemical changes?
500
A closed path along which an electric charge can flow.
It must have an energy source (battery) and a material that electrons can flow through easily (copper wire).
