1. Scientific Investigation
Lundquist

2. Science The study & explanation of a natural phenomena
The application of the scientific method
Starts with OBSERVING a phenomena
Lets observe a natural phenomena:
CLICK ME

3. Science Develop a hypothesis
A prediction based on previous observation
Can be a prediction on how something happens
DOES NOT have to be an if-then statement

4. Science Perform some sort of experiment Example: CLICK ME
A controlled situation in which you alter ONE thing
Example: CLICK ME

5. Variables Independent Variable Dependent Variable
The thing you have direct control over
What you change
The variable which is dependent on the IV
What you measure
Practice: What is the Hypothesis, IV, & DV,

6. Controls A test group that does not get the independent variable
Used as a comparison
How things behave normally?
Practice: What is the Hypothesis, IV, DV, Control?

7. Experimental design The more you test something the better
Minimum of 3 trails to make anything significant

8. Data The dependent variable values that you record Quantitative
Numerical values
Qualitative
How something feels, smells, tastes, behaves
also numbers

9. Representing data Pie graph – parts of a whole
Best done in:
Tables – rows of numbers, lists
Figures – graphs, drawings, pictures, etc.
Continuous – Previous point affects the next
Discontinuous – previous point does NOT affect the next

10. I don’t have to prove myself to you…
Conclusions
I don’t have to prove myself to you…
Attempts to explain WHY something happened
Either SUPPORTS or REJECTS the hypothesis
We don’t prove anything

11. Leads to: Theories Laws Attempts to explain WHY something happens
Theory of evolution
Observations that always happen
Law of gravity
