Step 2 Life Science Notes: Hypotheses, Experiment Planning, and Graphs

Vocabulary flashcards covering the formulation of hypotheses, experimental aims, and time graph layouts based on Step 2 Life Science notes.

Hypothesis

A written statement of one sentence that includes independent and dependent variables, uses clear and concise language, and excludes explanations, reasons, or personal bias.

Aim

The purpose of an experiment that starts with "to determine," mentions the independent and dependent variables, uses specific language, and avoids predictions.

Horizontal axis

The x-axis of a graph which contains the independent variable.

Vertical axis

The y-axis of a graph which contains the dependent variable.

Graph Axis Labeling

The requirement that each axis must be labeled and include units in brackets, such as temperature ($c$).

Independent variable placement

In time graphs, this variable is located on the horizontal or x-axis.

Dependent variable placement

In time graphs, this variable is located on the vertical or y-axis.
