The baseline group in an experiment that does not receive the experimental treatment.
What is the control group?
100
The horizontal axis on a graph where the independent variable is plotted.
What is the X-axis?
100
Glass container specifically used to measure exact liquid volumes in milliliters (mL).
What is a graduated cylinder?
100
The factor that a scientist deliberately changes or manipulates in an experiment.
What is the independent variable?
200
Information gathered directly using the five senses prior to forming a hypothesis
What is an observation?
200
All factors in an experiment that are kept identical across all test groups.
What are constants (controlled variables)?
200
The graph type best suited for tracking continuous changes over time.
What is a line graph?
200
Scientific tool used to determine the mass of an object in grams.

200
The factor that is measured or observed as the result or outcome of an experiment.
What is the dependent variable?
300
Measurements, observations, and facts collected during an investigation.
What is data?
300
Repeating a procedure multiple times within an experiment to ensure reliable data.
What are trials?
300
The graph type best suited for comparing distinct categories or discrete groups.
What is a bar graph?
300
The bottom point of the curve formed by a liquid surface in a cylinder, read at eye level.

300
In an experiment testing how fertilizer affects plant growth, plant growth is this variable.
What is the dependent variable?
400
A logical interpretation or conclusion based on prior knowledge and observations.
What is an inference?
400
An experimental flaw caused by altering more than one independent variable at a time.
What is an uncontrolled variable (invalid test)?
400
Identify the independent and dependent variables
400
Instrument used to measure thermal energy or temperature in degrees Celsius.

400
In an experiment testing how study hours affect exam scores, study hours is this variable.
What is the independent variable?
500
A well-tested explanation for a wide range of observations supported by extensive evidence.
What is a scientific theory?
500
When an independent scientist repeats an entire experiment to check if findings hold true.
What is replication?
500
A
