Scientific Method Steps
This is the first step of the scientific method.
Ask a question
A hypothesis should always be written what format?
If…then…
True or False: A hypothesis must always be correct.
False
A measure of how hot or cold something is, often measured in Celsius (°C).
Temperature
Information gathered with your senses.
Observation
After forming a hypothesis, this step comes next.
conducting an experiment
The variable that the scientist changes on purpose in an experiment.
Independent Variable
What do scientists do to share their findings?
Communicate results
Energy that makes things warmer; it can move from one object to another.
Heat
You test which brand of paper towel absorbs the most water. What is the dependent variable?
Amount of water absorbed
This step involves organizing results into charts or graphs.
analyzing data
Does the number of study hours affect test scores?
What would be the controlled variable?
Same test, same class, same grading
How many trials experiment
Three
An educated guess or prediction you can test, often written as “If…then…”
Hypothesis
You notice your soda is flat. What step of the scientific method are you doing?
Making an observation
The final step of the scientific method where scientists summarize what they learned.
drawing a conclusion?
The variable kept the same to ensure a fair test
Controlled variable
Water freezes at?
0 degrees Celsius
A test or procedure to see if a hypothesis is correct.
Experiment
What happens when your hypothesis is incorrect?
Start over and create a new hypothesis
Name the scientific method steps in order.
Question, Hypothesis, Experiment, Results, Conclusion
Does the amount of sunlight affect how tall plants grow?
What is the independent variable?
The amount of sunlight each plant gets
Why is Repetition important?
because it helps confirm that your experiment truly tests your hypothesis and that the results are valid.
A careful way to ask questions, test ideas, and find answers about the natural world.
Scientific Investigation
Which step comes after collecting data?
Analyzing data
