SCIENTIFIC METHODS

What are the constants in an experiment?

Back

Constants are the factors that remain unchanged throughout the experiment to ensure that the results are valid. Examples include pots, water, light, and type of plant.

What is the first step of the scientific method when you notice something interesting?

Back

Observe - This is when you notice something that sparks your curiosity and leads you to ask questions.

Front

What is the difference between Quantitative and Qualitative observations?

Back

Quantitative observations involve measurements and numbers (e.g., height in cm), while Qualitative observations involve descriptions and characteristics (e.g., color, texture).

Front

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment. It depends on the independent variable. For example, the height of plants when different amounts of fertilizer are applied.

Front

What does a hypothesis represent in the scientific method?

Back

A hypothesis is an educated guess or prediction about the outcome of an experiment based on prior knowledge or observations.

Front

What is the purpose of conducting an experiment?

Back

The purpose of conducting an experiment is to test a hypothesis and gather data to support or refute it.

Front

What is the role of a control group in an experiment?

Back

The control group is used as a standard for comparison. It does not receive the experimental treatment, allowing researchers to see the effect of the independent variable.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is the significance of data collection in scientific experiments?

Back

Data collection is crucial as it provides the evidence needed to support or reject a hypothesis and helps in drawing conclusions.

Front

What is a conclusion in the context of scientific methods?

Back

A conclusion is a summary of the results of an experiment, explaining whether the hypothesis was supported or not based on the data collected.
