Experimental Design & Scientific Method

What is the first step in the scientific method?

• Make an observation --> Question
• Design and conduct an experiment
• Make an hypothesis
• Share your results

The summary at the end of an experiment that explains the results is... 

• conclusion
• procedures
• materials
• responding variable

A testable prediction about a scientific investigation is a(n)

• Question
• Observation
• Hypothesis
• Experiment
