scientific method 1
What is the first step of the scientific method?
Formulate a hypothesis
Make observations
Draw conclusions
Analyze results
Make observations/ ask questions
A hypothesis should be:
Testable and measurable
Always correct
Only theoretical
A guess without basis
Testable and measurable
Predicting results before an experiment is part of:
Observation
Conclusion
Hypothesis
Measurement
