Scientific Method Practice

What step does every scientific experiment begin with?

• hypothesis
• question/problem
• procedures
• conclusion

The factors in an experiment that can be changed. 

• variables
• quantitative data
• hypothesis
• steps

This part of the experiment serves as a basis of comparison; the one variable being tested has been omitted. 

• experimental group
• control group
• data
• variables

This variable in an experiment is the one being deliberately changed by the scientist. 

• dependent variable
• independent variable
• data
• control group

There are two types of data. Which type of data involves numbers that are obtained by counting or measuring?

• quantitative
• qualitative

What is a hypothesis?

• A hypothesis is the right answer to an experiment.
• A hypothesis is the wrong answer to an experiment.
• A hypothesis is an educated guess.
• I don't know.

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

• The type of plant
• The amount of sunlight
• The type of music
• The type of liquid

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what are the constant variables?

• Type of plant, amount of music, and sunlight
• Water, apple juice, milk
• Plant growth

A list of the steps anyone could follow to conduct an experiment. 

• obervations
• question/problem
• materials
• procedures

The factor that will happen because of the change. 

• dependent variable 
• independent variable
• controlled variabe
• not this one.
