Lab/Science Practice Flashcard

Front

What is the purpose of a title in a graph?

Back

A title provides context and describes what the graph represents, allowing viewers to understand the data being presented.

Front

Is it safe to work alone in a science lab?

Back

No, it is not safe to work alone in a science lab due to potential hazards and the need for assistance in emergencies.

Why is it important to confine long hair and loose clothing in a lab?

Back

Confined hair and clothing prevent accidents, such as catching fire or getting caught in equipment.

Front

What is the independent variable in an experiment?

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is the significance of the x-axis in a graph?

Back

The x-axis typically represents the independent variable, allowing for the visualization of how it affects the dependent variable.

Front

What is the significance of the y-axis in a graph?

Back

The y-axis typically represents the dependent variable, showing the outcome of the experiment based on changes in the independent variable.

Front

What is a control variable?

Back

A control variable is a factor that is kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the independent variable.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
