Using the 5 senses to notice or describe events or processes in an orderly, careful way

• Observation
• Hypothesis
• Draw conclusions
• Controlled experiment

This is the step where we analyze what our graphed data could mean, and see whether that data supports or refutes our hypothesis.

• Hypothesis
• Observation
