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.
What is the independent variable?
The SI unit for length.
What is the meter?
100 centimeters equals this many meters.
What is 1 meter?
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.
What is the dependent variable?
The SI unit for mass.
What is the kilogram?
1,000 milliliters equals this many liters.
What is 1 liter?
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?
Convert 2.5 kilograms to grams.
What is 2,500 grams?
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)?
Convert 0.45 meters to centimeters.
What is 45 centimeters?
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?
500: A runner completes a 5-kilometer race. How many meters did they run?
What is 5,000 meters?
