Scientific investigations follow a standard process: 1) Ask a question and form a hypothesis to make a prediction about the outcome. 2) Design an experiment to test the hypothesis by manipulating variables and collecting data through observation and measurement. 3) Analyze the results to determine whether the data supports or refutes the original hypothesis.

1. THE SCIENTIFIC PROCESS

2. THE SCIENTIFIC PROCESS When doing an investigation, we need to follow a research method used by scientists.

3. PURPOSE: It is a question or statement about what you want to learn.

4. Hypothesis : My educated answer or prediction of the experiment outcome.

5. Plan how you will prove or disprove your hypothesis. (Your experiment) List all the materials you will need. Write down each step of everything you will do and number. (Other scientists should be able to repeat your experiment by reading your procedures. Why do you think this is important?) Experiment or Try your answer

6. Write down everything you observe with your 5 senses during the experiment. (These are the data.) Be honest. Report what you actually observe, not what you think should happen. Data Collection :

7. Analyze Results: Finding out what the experiment proves.

8. Study your data and think what it tell you about your hypothesis. Write a summary of what your experiment shows. Conclusion:

10. a variable is any measured characteristic or attribute that differs for different subjects . Variabl e:

11. : A variable that you believe might influence your outcome measure. This might be a variable that you control, like a treatment, or a variable not under your control, like an exposure. Independent variable :

12. Dependent variable In a research study, the variable that you believe might be influenced or modified by some treatment or exposure. It may also represent the variable you are trying to predict. In a research study, the variable that you believe might be influenced or modified by some treatment or exposure. It may also represent the variable you are trying to predict. Dependent variable

13. Controlled variable : A variable that does nor change or that we do not use to study the relationship between other variables without interference, or within subgroups of the control variable.
