Scientific Method Study Guide

What step does every scientific experiment begin with?

• hypothesis
• question/problem
• procedures
• conclusion

What two things need to be identified in your question?

• controlled variables and constants
• constants and independent variable
• independent and dependent variables
• dependent and controlled variables

This part of the experiment serves as a basis of comparison; the independent variable being tested has not been given to them. 

• experimental group
• control group
• data
• variables

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 controlled variables?

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

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. What would be an appropriate question for this experiment?

• What is the effect of the type of liquid used on the plant on how tall it grows?
• How tall can the plant grow?
• What is the effect of the plant's height on the different liquids we use?
• What happens to the different liquids if we change the height of the plant?

The summary at the end of an experiment that explains the results. 

• conclusion
• procedures
• materials
• responding variable

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. What would be the control group?

• The plant that gets apple juice
• The plant that gets water
• The plant that gets milk
• There is no control group

Testing a hypothesis often involves a(n):

• answer
• experiment
• problem
• safety check
