Importance/Steps

The outline of an experiment
- Hypothesis
  - Prediction before the experiment
- Independent variable vs Dependent Variable
  - The independent variable is what the scientist changes (x-axis)
  - The dependent variable is what responds to the independent variable (y-axis)
- Control vs Experimental
  - Control group is the one that does not receive the treatment (used as a comparison)
  - Experimental group receives the treatment
How to improve experiments
- Increase sample size
- Strategy of measuring/keeping track
- Control and Experimental group present
- Peer review
- Repeat experiment
Basic Measurement
- Ruler measurement
