1. A method by which natural phenomena are explained
Scientific Method
A method by which natural phenomena are explained

2. How would you describe what is happening here?
What do you notice? How do you think it happened?
What may have caused this to occur?
How do we avoid these problems?

3. How did you figure it out?
You used the scientific method.
This is not a new process for you.

4. Scientific Method Rules of the Game
One assumption: the phenomena to be described are able to be described by natural phenomena.

5. Steps of the Scientific Method
1. Make observations on something interesting
2. Form a hypothesis, an educated guess
3. Perform experiments to disprove or prove the hypothesis
4. Gather and analyze the data.
5. Make conclusions. Reevaluate the hypothesis. This never stops. Scientists make mistakes and they must retest their thoughts.

6. What do these words mean to you?
Observation (1) The act of attentive watching, perceiving, or noticing
(2) The data measured, collected, perceived or noticed, especially during an experiment
Hypothesis
A supposition or tentative explanation for (a group of) phenomena, (a set of) facts, or a scientific inquiry that may be tested, verified or answered by further investigation or methodological experiment. Essentially an educated guess about a known problem or question.

7. Conducting an Experiment
Control
a group in an experimental study that receives no special treatment
Can be a group or variable
Experimental group
-a group receiving special treatment in an experimental study
-This is your independent and dependent variables

8. So what’s the difference between these two groups anyway?
Independent variable
a variable that is manipulated or modified in an experiment
CAUSE
Dependent variable
a variable in an experimental study that may change as a result of the manipulation of the independent variable
EFFECT

9. What does this word mean to you?
Constant -Experimental constants are values that do not change either during or between experiments.
-Many natural forces and properties, such as the speed of light and the atomic weight of gold, are experimental constants

10. Variables are often graphed..
Independent variable
x axis
Dependent variable
y axis Y X

11. Qualitative versus Quantitative

12. How would you describe this picture?

13. Possible ways to describe it:
Number of people
Number of capes
Amount of face paint
Appearance of people
Type of clothes they are wearing
Type of surroundings

14. What does this mean? Quantitative Data Qualitative Data
a physical description involving the numbers of a situation
Qualitative Data
a physical description involving the physical appearance of a situation

15. What do these words mean to you?
Data Scientific data is defined as information collected using specific methods for a specific purpose of studying or analyzing. Data collected in a lab experiment
Conclusion
A conclusion is the final process of the basic scientific method by which scientists reveal whether the hypothesis was proven correct, it is normally one statement backed up by evidence backed up by data analysis, that supports or refutes the hypothesis.
Conclusions may warrant further study by other scientists who recheck the original experiment.

16. Once the reevaluation is over . .
Scientists have to test and retest hundred of time only then can you reach...
Theory: a tested explanation of natural phenomena
Law: a concise statement or mathematical equation about a relationship, i.e. E=mc2
