1. Scientific Method – Steps 1-2
A logical and organized method to solve a problem or answer a question
Problem - a question about the world
Why is the sky blue? Why do leaves change colors in autumn?
Background Information – conduct research from reliable sources

2. Scientific Method – Step 3
Hypothesis: testable statement
- Put hypothesis in the “If-Then” format.
- If _____ , then ______ will happen.
Example:
If the temperature of a cup of water is raised, then the amount of sugar that can be dissolved in it will be increased. 

3. Scientific Method – Step 4
4) Experiment: Test hypothesis and collect data
Independent variable – the one and only factor that is actually changed by the experimenter
Dependent variable(s) – factor(s) that change due to the effect of the independent variable (measured)
If the temperature of a cup of water is raised, then the amount of sugar that can be dissolved in it will be increased. 

4. Scientific Method – Step 4
Other parts of the Experiment:
Control –part experiment not exposed to the independent variable
Used to compare results to
Constants –factors that are kept the same for all parts of the experiment
Types of Constants: Temperatures, Light, Food type

5. Scientific Method – Steps 5 & 6
Analysis– Look at trends, patterns, differences, or similarities
Conclusion – Is hypothesis right or wrong?
- Use DATA as evidence
If hypothesis is wrong, what should you do?
….. proceed back to step 2 and try again
