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

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

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?)

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 :

Analyze Results: Finding out what the experiment proves.

Finding out what the experiment proves.

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

Study your data and think what it tell you about your hypothesis.

Write a summary of what your experiment shows.

 

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

:   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 :

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.
