Scientific Method
Series of organized steps used to solve a problem
Used by scientists and people around the world
6 main steps
Observation & Stating the Problem
Research
Hypothesis
Experiment
Analyze Data
Conclusion
LS.1 a-j The student will plan and conduct investigations

4. 1. Observation & Stating the Problem
All 5 senses (sight, smell, hearing, feeling, taste)
Gather information (just the facts)
Ex. The board is black
Stating the Problem
What could change or what causes what was observed?
Infer
Use observation & what you know to state what has happened
Ex. The board may be black b/c it doesn’t have chalk on it.

7. LS.1 a-j The student will plan and conduct investigations
3. Hypothesis
Educated guess
Based on research
If…. then statement
Shows how two variables are related
Variables
Things that can change in an experiment
3 types
Independent
Dependent
Controlled/Constants
LS.1 a-j The student will plan and conduct investigations

8. LS.1 a-j The student will plan and conduct investigations
Variables
Independent
You change on purpose
Manipulated variable IV
Control
Shows that its only the IV that causes the effect
Receives none of the IV (no change)
The standard used to compare with the outcome in an experiment
Dependent
Reacts/ responds to changing IV DV
What you measure in an experiment
Controlled Variable= constants
Things that can change, but you do not allow them to

12. Format for Writing a Hypothesis
If the __IV__ __(changes this way)__, then the __DV__ will ___(change this way)___.
Ex. Plants in the sun seem grow taller than plants in the shade.
IV = amount of sunlight
DV= height of plant
Hypothesis:
If the amount of sunlight increases then the plants height will increase.

Procedures used to test a hypothesis
at least 3 trials for each type of IV
Has Constants
Not allowed to change
Make more accurate
Gives data
Quantitative
Qualitative
