Scientific Method Quiz

Front

Dependent variable in an experiment:

Back

The factor being measured.

Answer explanation

The dependent variable in an experiment is the factor being measured. It reflects the outcome of changes made to the independent variable, allowing researchers to assess the effects of their manipulations.

Front

Experimental group: Receives the independent variable.

Back

Not the dependent variable, control group, or excluded from the experiment.

Answer explanation

The experimental group is the one that receives the independent variable, which is the factor being tested. This distinguishes it from the control group, which does not receive the independent variable.

Front

Control group:

Back

The group that does not receive the independent variable.

Answer explanation

A control group is essential in experiments as it does not receive the independent variable, allowing researchers to compare results against the experimental group that does. This helps isolate the effect of the independent variable.

Front

Controlled variables in an experiment are constant for both experimental and control groups.

Back

They do not change during the experiment.

Answer explanation

Controlled variables are those that remain constant across both the experimental and control groups to ensure that any observed effects are due to the independent variable. This helps maintain the integrity of the experiment.

Front

Hypothesis:

Back

An informed prediction about the relationship between variables.

Answer explanation

A hypothesis is not just a random guess; it is an informed prediction that suggests a relationship between variables, making it a foundational element in scientific research.

Front

First step in the scientific method?

Back

Ask a question.

Answer explanation

The first step in the scientific method is to ask a question. This initiates the process of inquiry and sets the stage for further investigation, leading to research and hypothesis formulation.

Front

Step of the scientific method for data collection:

Back

Test with an experiment.

Answer explanation

The step 'Test with an experiment' involves collecting data through observations and measurements during the experiment, making it the correct choice for this question.

Front

Step: 'Test with an Experiment' involves:

Back

Lists of materials and procedures.

Answer explanation

The step 'Test with an Experiment' involves creating lists of materials and procedures necessary for conducting the experiment, which is essential for ensuring the experiment can be replicated and results can be validated.

Front

Purpose of data analysis and conclusions?

Back

Review results, identify errors, and learn.

Answer explanation

Analyzing data helps to review results and identify sources of error, ensuring the validity of conclusions drawn. This process is crucial for refining hypotheses and improving future research.

Front

What to include in a hypothesis?

Back

Both dependent and independent variables in 'if ... then ...' format.

Answer explanation

A hypothesis should include both the independent and dependent variables, as it predicts the relationship between them. This allows for a clear understanding of what is being tested and measured.
