Scientific Method & Steps
The first step of the scientific method is this.
What is asking a question (or identifying a problem)?
The practice that means “making a guess based on observations.”
What is developing and using models?
The variable that you change on purpose in an experiment. (graphed on X-axis)
What is the independent variable?
The SI unit for length.
What is the meter?
Write the scientific notation of
3.5 x 106
3,500,000
This step involves making an educated guess that can be tested.
What is forming a hypothesis?
Designing and conducting experiments falls under this SEP.
What is planning and carrying out investigations?
The variable that you measure or observe as a result of the experiment. (It depends on the independent variable, and is graphed on the y-axis)
What is the dependent variable?
The SI unit for mass.
What is the kilogram?
What is the standard form of 6700?
6.7 x 103
After running an experiment, this step involves looking at graphs and tables to find patterns.
What is analyzing data?
When scientists read articles and compare their results, they are doing this SEP.
What is engaging in argument from evidence?
Factors that are kept the same so they don’t affect the results.
What are constants?
The SI unit for volume of a liquid.
What is the liter?
Why do we use scientific notation?
To make it easier to work with very large or very small numbers!
This step often leads to new questions and further experiments.
What is drawing a conclusion?
This SEP involves using math to show trends in data.
What is using mathematics and computational thinking?
The part of the experiment that is not changed and used for comparison.
What is the control group?
The SI unit for temperature.
What is the kelvin (or Celsius in most labs)?
Scientific notation of .0088?
8.8 x 103
This step involves sharing your experiment and results with the world, such as through reports or presentations.
What is communicating results?
This SEP means clearly describing your findings so others can understand and replicate them.
What is communicating information?
In an experiment testing plant growth with different amounts of sunlight, identify the independent and dependent variables.
What is independent = amount of sunlight; dependent = plant growth?
The SI unit for force, often measured with a spring scale.
What is the newton?
Standard form of 7.1 x 10-9
.0000000071
