Scientific Method

​Scientific Method

​Ms. Davis

A series of steps and procedures used to solve a problem through testing and experimentation.

​SCIENTIFIC METHOD

• Identify the problem

​

​Ask A Question?

• An explanation on why you think the problem happened.

• Educated guess

​

​

Form a Hypothesis

​A hypothesis is an assumption made before any research has been done. It is formed so that it can be tested to see if it might be true.​

​​Hypothesis

​

A theory is a principle formed to explain the things already shown in data.

​Theory

• Test hypothesis validity

• ​In experiments, scientist study factors called independent and dependent variables.

• Data support or reject a hypothesis ​

  ​

  ​

​

Design Experiment

Independent vs. Dependent

Changes in dependent variables depend upon the manipulation of the independent variable.

• Are observed and measured during an experiment; they are the experimental data.

​Dependent Variable

• The independent in an experiment is a condition that is manipulated, or changed.

​Independent Variable

• Collect data: Quantitative or Quantitative

• ​Analyze data to draw conclusion

​Make Observations

• Evaluate the date and conclusions presented by other scientists.

• Determine the validity of hypothesis

• Explains results

Make Conclusion

• Document results

​Communicate

Multiple Choice

A hypothesis is simply a prediction that has not yet been _.

Multiple Choice

What is the difference between Hypothesis and theory?

• Theory is an educated guess, a hypothesis is true data.

• A Hypothesis is an assumption based on a thesis and proven data.

• A hypotheis is an assumption that can be tested. A theory is a principle formed used to explain data.
