Variables
The definition of an independent variable
What is the variable you change?
Doing your experiment multiple times to make your results more reliable is called this.
What is repetition?
This explains why a natural phenomenon happens, based on lots of evidence.
What is a scientific theory?
The rigid outer layer of Earth that includes the crust and upper mantle.
What is the lithosphere?
The two processes that break down igneous rock into sediment.
What is weathering and erosion?
The variable that you measure
What is the dependent variable?
This improves the accuracy of your own experiment because it reduces error.
What is repetition?
This type of scientific knowledge can be changed or refined as new evidence is discovered.
What is a theory?
The layer of the Earth responsible for convection currents that move tectonic plates.
What is the mantle?
Sedimentary rock forms through these two main processes.
What are compaction and cementation?
The definition of a constant
What are the variables intentionally kept the same?
When different scientists perform your experiment to confirm the results, it is called this.
What is replication?
This describes what happens in nature, often with a mathematical formula.
What is a scientific law?
Name the two types of Earth’s core and describe their states of matter.
What is the outer core (liquid) and inner core (solid)?
This type of plate boundary causes earthquakes like the San Andreas Fault.
What is a transform boundary?
In an experiment to test how sunlight affects plant growth, this is the dependent variable.
What is plant growth?
This strengthens the validity of scientific findings because it shows results can be repeated by others.
What is replication?
This type of scientific knowledge summarizes observations that are consistently true in nature, but does not explain why.
What is a law?
The layer that generates Earth’s magnetic field due to the movement of liquid metal.
What is the outer core?
The type of plate boundary where crust is made.
What is a divergent boundary?
This group in an experiment does not receive the independent variable and is used for comparison.
What is the control group?
If you grow the same plant under the same light conditions 10 times, you are practicing this. If another lab does the same experiment and gets similar results, they are practicing this.
What are repetition and replication?
T/F: Theories can become laws with more research.
What is false?
The layer that makes up most of Earth’s volume and is responsible for transferring heat through convection currents.
What is the mantle?
An event that happens quickly due to plate movement.
What is an earthquake?
