Experimental Design

Front

What is Experimental Design?

Back

Experimental Design is a method used to plan and conduct experiments in a way that ensures valid and reliable results.

Front

Why should experiments be repeated?

Back

Experiments should be repeated to verify that the results are consistent and reliable.

Front

What is a dependent variable?

Back

A dependent variable is the factor that is measured in an experiment, which changes in response to the independent variable.

Front

What is an independent variable?

Back

An independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

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

Back

A control group is used as a standard for comparison, helping to isolate the effects of the independent variable.

Front

What are trials in an experiment?

Back

Trials refer to the number of times each level of the independent variable is tested.

Front

What is the importance of constants in an experiment?

Back

Constants are factors that are kept the same throughout the experiment to ensure that the results are due to the independent variable.

How does temperature affect the rate of dissolving?

Back

In experiments, varying the temperature can show how it influences the speed at which substances dissolve.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

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.
