Steps of the Scientific Method
What is the first step of the scientific method
Ask a question (Problem Statement)
A hypothesis should always be written in this format
“If…then…
A measure of how hot or cold something is, often measured in Celsius (°C).
Temperature
How many trials do you conduct in a experiment?
Three
You want to know if different types of soil affect how fast plants grow. What step of the scientific method are you doing?
Asking a question
After forming a hypothesis, this step comes next.
Conducting an experiment
The variable that is measured or observed during an experiment.
Dependent variable
Energy that makes things warmer; it can move from one object to another.
Heat
Water freezes at what temperature in Celsius?
0 degrees Celsius
A student predicts, “If we use warmer water, then sugar will dissolve faster.” What step is this?
Making a hypothesis
This step involves organizing results into charts or graphs.
analyzing data
The variable that's kept the same
controlled variable
Using your senses to notice and describe something carefully.
Observation
Heat always moves from hot to cold
Is this true or false?
True
You test which brand of paper towel absorbs the most water. What is the dependent variable?
Amount of water absorbed
The final step of the scientific method where scientists summarize what they learned.
Conclusion
The amount of sunlight each plant gets.
What type of variable is this?
Independent variable
A careful way to ask questions, test ideas, and find answers about the natural world.
Scientific Investigation
The scientific method can be used in everyday life.
True or False?
True
A scientist tests if music affects how fast you read. What is the independent variable?
The type of music
Name the scientific method steps in order
Question, Hypothesis, Experiment, Data, Conclusion
What happens if your hypothesis is wrong
Start over and make a new one
A test or procedure to see if a hypothesis is correct.
Experiment
What do scientists do to share their findings
Communicate results
