EOC Review Physics Part1

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

• scientific method
• recipe
• data collection
• metric system

Testing a hypothesis often involves a(n):

• answer
• experiment
• problem
• safety check

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

• dependent variable
• independent variable
• data
• control group

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
