A visual representation of the degree of error or uncertainty associated with a measurement.

A proposed explanation for an observation or question that can be tested.

The variable that is measured in an experiment.

The variable that is intentionally changed or manipulated in an experiment.

Data that describes qualities or characteristics, often based on observations of senses.

Data that can be measured and expressed numerically.

A systematic approach used by scientists to investigate and answer questions.

Testing a hypothesis in a controlled setting or environment.

A factor that is kept constant throughout an experiment to ensure that the results are due to the independent variable only. It remains unchanged for all experimental subjects.

The scientific method is a systematic way of asking questions, testing hypotheses, and gathering evidence to understand the world around us. It helps us make logical conclusions about the world based on evidence.

In the plant experiment, the controlled variables include the type of plant, the size of the pots, and the duration of the experiment (2 months). These factors are kept the same for both plants to ensure a fair comparison.

The independent variable is the duration of sunlight exposure, with one plant getting 6 hours and the other 2 hours of sunlight per day. Scientists change this factor to study its impact on plant growth.

The dependent variable is the growth of the plant, measured in centimeters. This is what is being observed and measured as a result of the change in sunlight exposure.

Quantitative data is numerical data that can be measured and expressed as numbers, while qualitative data describes qualities or characteristics using words, observations, and descriptions.
