Scientific Method

A possible explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

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

• dependent variable
• independent variable
• data
• control group

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

• conclusion
• procedures
• materials
• responding variable

A series of steps used by scientists to solve a problem or answer a question. 

• scientific method
• recipe
• data collection
• metric system

In a controlled experiment, how many independent variables can be worked with at a time? 

• one
• none
• two or more
• how ever many makes sense.

Mr. Appis sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp.  Identify the independent variable.

• distance traveled by the ball
• height of the ramp
• mass of the ball
• weight of the ball

Mr. Appis sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp.  Identify the dependent variable.

• height of the ramp
•  distance traveled by the ball
• mass of the ball
• weight of the ball

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 is the dependent variable?

• Type of plant
• Water, apple juice, milk
• Plant growth
• Color of the plant's leaves

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.

Which is NOT a step in the scientific method?

• Make observation
• Form a theory
• Collect data
• Form a hypothesis
