Scientific Method
A proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Hypothesis
The 4th planet from the sun
Mars
Rock that starts out molten and solidifies as it cools
Igneous Rock
Facts and statistics collected together for reference or analysis.
Data
an irregularly shaped rock that orbits the sun
Asteroid
Rock that has been changed by extreme heat and pressure
Metamorphic Rock
In scientific experimentation is the experimental element which is constant and unchanged throughout the course of the investigation.
Controlled Variable
A space object made of ice and dust that orbits a star and develops a long bright tail as it nears its star
Comet
Rock that is forms from depositions and solidification of sediment
Sedimentary Rock
A variable whose variation does not depend on that of another.
Independent Variable
A hole in the ground caused by the impact of an object from space
Crater
Gradual destruction by water, wind, or other natural agents
Erosion
Variable whose value does depend on that of another.
Dependent Variable
The force that pulls all objects towards each other
Gravity
