The Scientific Method 1
Numerical information that can be measured or counted (Involves
numbers).
What is Quantitative Data
A controlled procedure (fair test) carried out to test a hypothesis.
What is an experiment.
Descriptive information that is not expressed in numbers, often based on
characteristics such as color, texture, or smell (Describes qualities).
What is Qualitative Data
The factors that are kept the same throughout an experiment.
What is a Controlled Variable (Constant)
A summary based on the results of an investigation, stating whether the
hypothesis was supported or not.
What is a Conclusion
Facts, figures, and other evidence gathered through observation or experimentation.
What is Data
What is the first Step in the Scientific Method?
What is Observe and Ask Questions
An educated guess that can be tested. Written as an if / then statement (If all
light is blocked from a plant for two weeks, then the plant will die.)
What is Hypothesis
How is a Hypothesis written?
What is an If/Then statement.
What is the fifth Step in the Scientific Method?
What is the Second Step in the Scientific Method?
What is a Hypothesis.
The factor being measured or tested in an experiment that changes
as a result of the manipulation of the independent variable.
What is the Dependent Variable
What is the Third Step in the Scientific Method?
What is an Experiment
Observation - Gathering information using the senses (what you see, feel, hear, taste, or
smell).
What is an observation
What is the Fourth Step in the Scientific Method?
What is to Analyze Data
A step-by-step process used for investigating the world around us, that
includes observation, forming a hypothesis, experimentation, collecting and analyzing data,
and conclusion.
What is the Scientific Method
A statement about what will happen in the future based on current evidence or
knowledge.
What is a Prediction
The factor that is purposely changed or manipulated by the
experimenter in an experiment to observe its effects.
What is the Independent Variable
A student wants to see if more sunlight will make her plants grow taller. What are the constants?
What is the pots, amount of water, plants, etc.
The process of examining data to understand and interpret the results of an
experiment.
What is an Analysis
A student wants to see if more sunlight will make her plants grow taller. What is the Dependent Variable?
What is the height of the plants.
What are the 5 steps in the Scientific Method
1. Observe and Ask Questions
2. Make a Hypothesis
3. Experiment
4. Analyze Data
5. Make a Conclusion
A student wants to see if more sunlight will make her plants grow taller. What is the Independent Variable?
What is he amount of Sunlight.
A useful tool for making approximate measurements and giving general
descriptions.
What is an Estimation
An explanation based on observations or background knowledge.
What is an Inference
