Scientific Method
A series of steps designed to help you solve problems and answer questions
A) scientific method
B) experiment
C) hypothesis
D) observation
A) scientific method
When a scientist shares her findings with other scientists, she is
A) analyzing data
B) making a hypothesis
C) experimenting
D) communicating results
D) communicating results
What is the 1st step of the scientific method?
Ask a Question/Identify Problem
The information (evidence) gathered from observations and experimentation is
Data
Scientists are the only individuals who use the scientific method True or False
False - WE ALL USE IT
What is the last step of the scientific method?
Draw conclusions and communicate them
What is a Law?
broad concept or principle (HOW)

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.
D) If I freeze a tennis ball, then it will not bounce as high.
Numerical Data and Measurements is quantitative or qualitative?
Quantitative
Descriptive or Physical Data is Quantitative or Qualitative?
Qualitative
A Possible Explanation or answer to a scientific question that can be tested in an experiment
Hypothesis
What does theory mean?
An explanation of an observed phenomenon
Observation
We compare our experimental data by including a
A. Control Group
B. Uncontrolled Group
C. Experimental Group
D. Observation Group
A Control Group
Before you can form a hypothesis, you need to
a. state the problem or question
b. perform an experiment
c. state a conclusion
a. state the problem or question
What can a conclusion of an experiment do
Make an explicit statement about whether your hypothesis was supported or rejected by your experimental data
Data may support your prediction
Data may fail to support (reject) your prediction
NOTE: Data does NOT prove/disprove!!
Describe any real-world applications/uses for the information learned from the investigation
The foundation for any experimental process is
a. | read all the instructions very carefully. | c. | Labeling Materials. |
b. | Thorough Research w/ Reputable Sources. | d. | Creating Hypothesis. |
B - Thorough Research with Reputable Sources
The variable that is deliberately changed/manipulated
A. | Dependent |
B. | Independent |
C. | Control |
D. | Uncontrolled |
B- Independent
Difference preservatives were tried in foods to determine which best restricted the growth of molds. What is the dependent?
Growth of Mold
The rate of reaction was 20mL of oxygen per minute. What is this an example of?
Quantitative Data
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
A) the types of plants or B) the amount of salt in the water
the amount of salt in the water
What are the steps to the scientific method?
5: Ask Question, Form Hypothesis, Create Experiment, Analyze Data, Form Conclusion, Communcate Results
In an experiment, the factor that we measure is called the
dependent variable.
A hypothesis must be stated in a form that is
testable
A researcher conducted an experiment to see if temperature effected the blooms of a rose bush... What is the independent variable?
The temperature
