Scientific Method
A series of steps designed to help you solve problems and answer questions
the Scientific Method
When a scientist shares her/his findings with other scientists, she/he is
communicating results
What is the 1st step of the scientific method?
Ask a Question
The control of an experiment never gets this applied, what kind of variable is?
the Independent Variable
"Scientists are the only individuals who use the Scientific Method"
What kind of statement is that?
false!
This is the first step of the Scientific Method
Ask a Question
how many senses we use in the observation step?
all the senses
Only one of the hypothesis is written correctly

an Hypothesis
Gathering information by using your senses

Before you can form a hypothesis, you need to do this
Research
This step comes after you analyze your data
drawing a conclusion

control
The variable that is changed or manipulated in an experiment.
Independent Variable
what is an independent variable?
is one that you can change in an experiment
what is data?
information and observations gathered during your project. often organized into tables and graphs
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the plants that can live in the water. In this experiment the independent variable is
the amount of salt in the water
These are the 7 steps of the Scientific Method
Ask Question, Research, Form Hypothesis, Create Experiment, Analyze Data, Form Conclusion, Communicate Results
The variable that represents the outcome or effect in an experiment
Dependent Variable
If the results of your experiment do not make sense, the best thing to do is do these two things
revisit your hypothesis and modify your experiment
