Control Group

The group in the experiment that has the same conditions as the experimental groups except for the independent variable

Independent Variable

The variable that is changed in an experiment

Dependent Variable

The variable that is measured in an experiment

Scientific Method

Steps that scientists use to answer questions and solve problems

Error

A mistake that could have been made during an experiment

Conclusion

The end results of the experiment and how the results relate to the hypothesis

Data Table

A chart used for collecting and organizing observations and measurements

Procedure

Steps involved in performing an experiment. (directions)

Purpose

Materials

The items needed to conduct the experiment.

Experimental Group

In an experiment, the group that is exposed to the treatment or the independent variable

Safety

Being free of danger and injury

Experiment

X-Axis

Horizontal line of the graph

Y-Axis

Vertical line of the graph

Line Graph

A graph used to show how data changes over a period of time

Bar Graph

A type of graph used to compare data in categories or groups

Title

A detailed name for the graph

Labels

A name for the X and Y axis

Units

The value that something is measured in (Ex: grams, milliliters, centimeters) All numbers require this

Key

If a graph has two or more types of data, an illustration of what each line represents is needed. (different colors, shapes, or lines)

Graph

A visual display of information or data

Horizontal

Line at the bottom of the graph going left and right. This is the X-Axis

Vertical

Line on the side of the graph going up and down. This is the Y-Axis

Data Point

A point on a graph showing the location of a piece of data.
