Scientific Method
A series of steps designed to help you solve problems and answer questions
What is the Scientific Method?
When a scientist shares her findings with other scientists, she is
What 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 is the Independent Variable?
"Scientists are the only individuals who use the Scientific Method"
What kind of statement is that?
What is false!
This is the first step of the Scientific Method
What is Ask a Question?
Observations in an experiment must all be this, which is, free of personal opinion
What is objective?
Only one of the hypothesis is written correctly
A) If a tennis ball is frozen, it won't bounce as high
B) If I heat up a tennis ball it will bounce high.
C) Frozen tennis balls will not bounce as high.
D) If I freeze a tennis ball, then it will not bounce as high.
What is answer choice D? If I freeze a tennis ball, then it will not bounce as high.
This is a type of observation that involves measurements like length or temperature
What is Quantitative
Observations like color, texture, size, or some other quality are known as
What is Qualitative?
This is an educated guess about the outcome of an experiment
What is a Hypothesis?
When you are making a judgement based on prior experience, you are making this
What is an inference?
Gathering information by using your senses
What is observation?
In order to be sure all experimental groups are treated fairly, scientists MUST include these
What are constants?
Before you can form a hypothesis, you need to do this
What is Research?
What is drawing a conclusion?
In an experiment, the example of what would happen if the Independent Variable were never tested is this
What is the control?
The variable that is changed or manipulated in an experiment.
What is the Independent Variable?
Different preservatives were tried in foods to determine which best stopped the growth of molds. What is the dependent variable?
What is the growth of Mold
If a scientists experiment is influenced by their opinions or if the groups are not treated fairly, they could be accused of having this
What is Bias?
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
What 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
What is the Dependent Variable?
If the results of your experiment do not make sense, the best thing to do is do these two things
What is revisit your hypothesis and modify your experiment?
A researcher conducted an experiment to see if temperature effected the blooms of a rose bush.
What is the independent variable?
What is the temperature?
